Dorsolateral prefrontal cortex and hippocampus sustain impulsivity and aggressiveness in borderline personality disorder.

BACKGROUND: Borderline Personality Disorder (BPD) patients are characterized by increased levels of aggressivity and reduction of impulse control, which are behavioural dimensions mainly sustained by hippocampus and dorsolateral prefrontal cortex (DLPFC). In this study we aimed at investigating whether hippocampus and DLPFC anatomy may sustain impulsive and aggressive behaviours in BPD. METHODS: Fifteen DSM-IV BPD patients (11 females, 4 males) and fifteen 1:1 matched healthy controls (11 females, 4 males) were studied with a 1.5T magnetic resonance imaging (MRI) and underwent a psychopathological assessment in order to measure the severity of aggressive and impulsive traits. RESULTS: Right hippocampal volumes were significantly reduced in BPD patients compared to healthy subjects (p=0.027), particularly in those with a history of childhood abuse (p=0.01). Moreover, in patients but not in controls, right hippocampal volumes significantly inversely correlated with aggressiveness and DLPFC grey matter volumes significantly inversely associated with impulsiveness (p<0.05). CONCLUSIONS: Our results provide evidence that hippocampus and DLPFC play a separate and unique role in sustaining the control of impulse and aggressive behaviours in BPD patients.

OEM-TACE: a new therapeutic approach in unresectable intrahepatic cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (ICC) is a rare life-threatening disease, whose only treatment with potential for cure is surgical resection. However, only 27% of patients at most are suitable for surgery when first diagnosed. For patients with unresectable disease, therapeutic options are chemotherapy or chemoradiation. We evaluated the feasibility and safety of oxaliplatin-eluting microspheres transarterial chemoembolization (OEM-TACE) associated with chemotherapy (ChT) in patients affected by unresectable ICC. Between December 2005 and May 2008 we treated nine patients (six female and three male) with unresectable ICC. All patients had undergone OEM-TACE associated with chemotherapy with oxaliplatin and gemcitabine. A retrospective comparison was carried out with a historical group of 11 patients treated with ChT only, estimating the prevalence of adverse effects and the median survival of the two groups. A total of 30 TACEs were performed during the observational time (ranging from one to seven procedures per patient). OEM-TACEs were followed by few adverse effects (AEs), without G4 AEs, according to CTACAE 3.0. According to RECIST criteria, 44% (4/9) of patients achieved partial responses and 56% (5/9) stabilization of disease. Overall survival analysis in the two groups showed a significantly increased survival in patients treated with ChT and OEM-TACE, with respect to those treated with ChT (30 vs. 12.7 months; p=0.004). In conclusion, in our experience OEM-TACE associated with ChT in the treatment of advanced unresectable ICC is a safe and feasible treatment causing no major adverse events. Although RECIST criteria can underestimate the rate of responses in patients treated with locoregional therapies, we achieved very encouraging results. A randomized multicentric trial is warranted to assess the actual superiority of OEM-TACE associated with ChT compared to conventional chemotherapy.

Osteoid osteoma of the cervical spine: surgical treatment or percutaneous radiofrequency coagulation?

Osteoid osteoma (OO) of the cervical spine is frequently located close to the vertebral artery, spinal cord, or nerve roots and complete surgical excision is sometimes difficult by a limited approach and more extended surgery can require spinal fusion. Percutaneous radiofrequency coagulation (PRC) has demonstrated efficacy in the treatment of OO of the pelvis and limbs however, its role in the cervical spine is still nuclear. The Authors present a series of nine cases of OO of the cervical spine, six treated with surgical excision and three with PRC. No neurological or vascular complications occurred in both series. One case of the surgical series had only partial relief of persistent pain for 1 year due to incomplete excision, but is doing well 4 years after surgery. All the other surgical cases had complete relief of symptoms immediately after surgery and are symptom-free 3-10 years later. Two cases of PRC had complete relief of symptoms 24-48 h after surgery and are symptom-free 2 and 3 years later. One case of recurrent OO after surgery and treated with PRC with a reduced dose improved only, and still requires anti-inflammatory drugs 2 years after the procedure. Our still limited experience suggests that PRC can be safely performed in local anaesthesia with the patient awake, enabling to check for signs and symptoms of possible neurological injury. PRC can substitute extensive posterior approaches and reconstructions for OO of the posterior arch and joint pillar.

A randomized phase III study: comparison between intravenous and intraarterial ACNU administration in newly diagnosed primary glioblastomas.

BACKGROUND: In this randomized phase III study, the effectiveness as well as the side-effects of intraarterial [i.a.] (17 patients) versus intravenous [i.v.] (16 patients) ACNU [Nimustine] administration in newly diagnosed glioblastoma, were compared. PATIENTS AND METHODS: All patients undenwent extensive surgical resection, and both groups were homogeneous for the other known risk factors. Thirty-three patients with glioblastoma were treated with ACNU at the dose of 80-100 mg/m2. Treatment was repeated every 5-8 weeks for a minimum of 2 and maximum of 14 cycles. Total survival time (TST) and to time to progression were chosen as outcome variables. RESULTS AND CONCLUSION: No significant differences in systemic and hematological toxicity between the i.a. and iv. ACNU administration routes were detected. In both groups, tolerance of the procedure was excellent. Analysis of the main outcome measured showed no significant differences between i.a. and i.v. ACNU administration: time to progression was 6 months for i.a. ACNU and 4 months for i.v. ACNU and total survival time was 17 months for i.a. ACNU and 20 months for i.v. ACNU. In spite of ACNU dose incrementation, obtained through i.a. route administration, and subsequent higher concentration in the tumor bed, no improvement could be achieved in effectiveness.

Disseminated intravascular coagulation during total hip replacement.

Disseminated intravascular coagulation (DIC) is an extremely serious hemorrhagic disorder and one that is potentially lethal. DIC is more frequently observed as a complication of obstetric pathologies, diffused neoplasms, bacterial sepsis, blood transfusions, traumas and adipose embolias. The literature reports very few cases occurring after total hip replacement, two of which the cause of death. In all of the cases described one or boh prosthetic components are cemented. The authors report a case observed after total hip replacement in a patient submitted one year previously to contralateral hip replacement. Severe hypotension, bradychardia and profuse bleeding of the wound and from the drainages one hour after suturing constituted the initial symptom. Recognition of the clinical findings, after exclusion of a iatrogenic lesion, and subsequent treatment in intensive therapy allowed us to save the patient. The syndrome must be suspected and immediately diagnosed when profuse bleeding that cannot be related to vascular lesion is observed immediately postsurgery after cemented or hybrid hip replacement. Confirmation through hematological tests and timely treatment in a specialized center are indispensable requirements to save the life of the patient.

The effects on auditory neurocognitive evoked responses and contingent negative variation activity of frontal cortex lesions or ablations in man: three new case studies.

Our previous research in patients with extensive surgical ablations of the prefrontal cortex contradict the hypothesis of some authors that the generators of several auditory event-related potentials (ERPs) (N100; P200; N200; P300; SW), recordable in humans with depth/scalp electrodes and MEG over the prefrontal dorsolateral cortical areas, are essentially located in medial prefrontal and anterior cingulate-limbic cortices. Using a standard CNV paradigm, 21 EEG electrodes and topographic mapping analysis, the post-warning (S1) auditory N100a b c, P200, P300 (binaural clicks) and CNV activity were recorded in three additional patients after extensive dorsolateral and/or medial prefrontal cortex ablations, verified through CT/MRI examinations. No true post-S1/CNV components were recordable over the ablated frontal areas, only sporadic volume-conducted ERPs probably generated in the temporo-parietal lobes or posterior cingulate gyrus. For one of these patients, after excision of a vast right frontal epileptogenic cortical region (including extensive dorsolateral areas, but sparing the fronto-medial cortex and anterior/middle cingulate gyrus), no post-S1/CNV components were recordable over the ablated regions. These latest observations again indicate that independent neuronal generators of several post-S1 auditory and CNV components are located in the dorsolateral supramodal premotor/prefrontal cortical areas which are directly, ipsilaterally connected to the uni/multimodal temporo-parieto-occipital sensory and associative regions through the long, two-way, fairly superficial, superior arcuate-longitudinal and deeper superior and inferior occipito-frontal bundles. Clear and almost constant differences in the latency of some post-S1 N100 subcomponents (especially the time-lapses between onset and the highest amplitude of the N100 a and c) over various posterior, central and anterior cortical areas sequentially involved, roughly measured in 10 normal subjects along the scalp and with MRI cerebral imaging, may probably be accounted for by the transcortical homohemispheric conduction time, which varies in our scalp recordings from 1 cm/0.74-1.28 ms, mean approximately 1 cm/1.02 ms ( approximately 9.8 ms).

Induction chemotherapy by superselective intra-arterial high-dose carboplatin infusion for head and neck cancer.

To evaluate the feasibility, maximum dose of drug tolerated, technical problems, systemic and local toxicity, response rate, overall and disease-free survival, we studied superselective intra-arterial infusion of high-dose carboplatin as part of a multimodality treatment for head and neck cancer. Forty patients with untreated stage II-IV head and neck squamous cell carcinomas received induction chemotherapy with high-dose carboplatin (three cycles at 2-week intervals using 300-350 mg/m2 per cycle), delivered via superselective transfemoral angiography followed by radiotherapy or surgery plus radiotherapy. No technical complications occurred during or after the infusion. Systemic toxicity was minimal, and local toxicity was moderate. At the end of chemotherapy the overall complete and partial response rate was 90% (36/40) at the primary site and 64% (16/25) at the neck nodes. The median follow-up was 24.4 months (range 3-52). To date 21 patients are alive without disease, 2 are alive with disease, 13 have died of disease, and 4 have developed a metachronous lung tumor. There was a good correlation between the response to chemotherapy and disease-free survival. No statistically significant benefit in survival was observed with respect to other series of head and neck tumors treated with different protocols. However, discriminating between responding and nonresponding patients, this procedure can have a prognostic significance in planning integrated treatments for these types of tumors.

Vasomotor response to CO2 and L-Arginine in patients with severe internal carotid artery stenosis; pre- and post-surgical evaluation with transcranial Doppler.

BACKGROUND AND AIM: Carotid artery disease may cause both thromboembolism and cerebral blood flow disturbances, particularly in subjects with impaired hemodynamic compensatory mechanisms. The aim of this study was to evaluate by transcranial Doppler (TCD) the hemodynamic changes induced by CO2 and L-Arginine stimulation in a selected population with severe unilateral carotid stenosis (70-80%), before and after carotid endarterectomy, in order to determine the effect of surgery in the vascular hemodynamics of these patients. METHODS: We studied 20 subjects (mean age 66.4 years) consecutively admitted to our institute with ischemia and unilateral severe internal carotid artery stenosis (70-80%) detected by Color Doppler. All patients underwent arterial digital subtraction angiography to confirm the ultrasonographic evaluation. TCD was performed bilaterally; blood flow velocity was monitored during CO2 and L-Arginine stimulation both in basal conditions and three months after surgery. RESULTS: After endarterectomy, mean velocity increased in response to both stimuli with a trend toward statistical significance. A significantly lower reactivity to L-Arginine on the stenotic side was found in the pre-operative phase: this asymmetrical reactivity was no longer observable after carotid endarterectomy. CONCLUSIONS: We found a statistically significant difference in L-Arginine reactivity in the stenotic side of patients with severe unilateral internal carotid stenosis. This is probably related to an alteration of the endothelium function due to the carotid pathology, since the abnormalities disappeared three months after endarterectomy.

Intralesional surgery of primary tumors of the anterior cervical column.

The study involves a series of 10 primary neoplasms of the anterior cervical column (body and transverse processes) surgically treated by intralesional excision and followed-up after 2-10 years. The series included 6 benign and 4 malignant neoplasms. Among the benign tumors 4 cases were classified Enneking stage II (2 osteoid osteomas, 1 fibrous dysplasia, 1 osteoma): after simple excision none of the cases revealed symptoms or signs of recurrence at long-term follow-up. The other 2 benign forms were stage III (giant cell tumor and aneurysmal cyst): both of the cases were treated by extracapsular intralesional excision after selective arterial embolization and reconstruction with anterior fusion; the giant cell tumor was irradiated after surgery: at long-term follow-up the patients were asymptomatic and there were no signs of recurrence. The 4 malignant neoplasms (stage IIB) were 1 osteosarcoma and 3 solitary plasmacytomas with spinal cord compression. The osteosarcoma was treated by intralesional excision in 3 stages and radiation therapy, and there were no signs of disease 6 years after diagnosis. The cases of plasmocytoma were treated by intralesional excision and spinal cord decompression, anterior fusion with iliac graft and plate, radiation therapy, and chemotherapy, and they died after 2, 3 and 4 years with findings of multiple myeloma with no signs of disease at the level of the cervical vertebra treated.

Anterior surgery in trauma of the cervical spine.

The study reports a series of 37 traumatic lesions of the cervical spine treated surgically by anterior approach. The series includes two IInd type fractures of the odontoid, treated by direct screwing, 32 recent fractures or fracture-dislocations of the lower cervical spine treated by decompression and anterior arthrodesis with a plate, 3 inveterate dislocations treated by anterior-posterior osteotomy in 2 cases, and decompression-arthrodesis in the third. One amyelic fracture of the odontoid healed in 4 months, the other patient, with Frankel C spinal cord lesion improved to D, but died 4 months later as a result of bronchial pneumonia ab ingestis. In all of the recent lower cervical lesions fusion was obtained in 3-12 months (mean 4.5 months). Eight incomplete spinal cord lesions improved by 2 Frankel classes in 3 cases and by 1 in 5. Six nerve root lesions healed with complete recovery. Three cases with no neurologic deficit remained unchanged as did 15 complete spinal cord lesions. In the 3 inveterate cases we obtained healing of a slow-developing myelopathy (Frankel D) after osteotomy, no improvement after osteotomy in the second case (Frankel B). In the case submitted to decompression and anterior fusion we obtained recovery from Frankel B to E in three months, but the patient then died as a result of pulmonary complications. Direct screwing of the odontoid allows us to obtain healing of the type II fractures without blocking C1-C2 movement with a posterior fusion. Anterior surgery in traumas of the lower cervical spine allows for anatomical decompression of the spinal cord and bone reconstruction with good results, avoiding the risk of neurologic progression caused by dragging of the disc material in the spinal canal, that may take place at the time of non-surgical reduction or by posterior approach of the dislocations. In our series complications included 2 infections, 1 that healed without sequelae and the other with kyphosis, and a fistula of the hypopharynx caused by fibrobronchoscopy 1 year after osteosynthesis, that healed after primary repair. For this latter complication anterior surgery can, at most, be considered a contributing cause, because of the deep scar.

Transsynaptic degeneration of lateral geniculate bodies in blind children: in vivo MR demonstration.

PURPOSE: To investigate signal alterations in the thalamic lateral geniculate bodies of blind patients compatible with transsynaptic degeneration of these nuclei caused by pregeniculate or postgeniculate interruption of the visual pathway. METHODS: Six patients were selected from a group of blind children in our care. Four had cerebral palsy caused by periventricular leukomalacia, one had infantile neuroaxonal dystrophy, and one had Chiari I malformation and hydrocephalus, which was worsened by bilateral ischemic lesions of the occipital lobes. MR examinations (obtained at 0.5 T) were reviewed retrospectively by two neuroradiologists, with particular attention to the visual pathway. RESULTS: Symmetric, focal areas of T2 prolongation were found at the precise site of the lateral geniculate bodies. CONCLUSION: Anterograde (pregeniculate) and retrograde (postgeniculate) transsynaptic degeneration of the second neurons of the visual pathway produce alterations in MR signal.

MRI and brainstem auditory evoked potential evidence of eighth cranial nerve involvement in multiple sclerosis.

An MS patient experienced sudden hearing loss. Brainstem auditory evoked potentials, previously normal, showed substantial abnormalities that suggested the impairment of the distal part of the acoustic nerve. MRI detected a small hyperintense lesion along the acoustic nerve; the lesion decreased in size and then disappeared after steroid treatment. This demonstrates that a demyelinating lesion in the distal tract of the eighth cranial nerve may cause an acute hearing loss in MS.

Review of the Literature. Super-selective Chemotherapy with High Dose Carboplatin for Advanced Cervicofacial Tumours. Treatment Validation and Preliminary Findings in 22 Patients.

SUMMARY: Traditional treatment based on surgery combined with radiotherapy for stage III and IV cervicofacial squamous cell carcinomas has shown disappointing results to date. In the past, systemic chemotherapy was only used as a palliative treatment. Intra-arterial chemotherapy offers theoretical advantages mainly linked to increased drug tolerability. This new technique seems particularly suited to the management of squamous cell carcinomas in view of the local and regional spread of these tumours and the improved access by means of angiographic adminstration through the branches of the external carotid artery. We describe our experience of intra-arterial chemotherapy in 22 patients with biopsy-proven squamous cell carcinoma at the onset of disease. High dose Carboplatin (300-350 mg/m(2)) was super- selectively injected by rapid infusion repeated in three sittings at two week intervals. The optimum point of drug infusion was determined in each patient on the basis of angiographic information obtained in the diagnostic work-up. The dual objective was to get as near as possible to the primary tumour and to infuse the drug into any satellite lymph node metastases. The narrow calibre and tortuous course of the branches of the external carotid artery increase the likelihood of vasospasm: 5F hydrophilic catheters proved very useful to minimize technical complications in all angiographic procedures performed (64). Treatment was always well tolerated with mild local toxicity (grade 1-3, WHO), mainly involving the mucosae (stomatitis) and skin (dermatitis and alopecia) and minimum myelosuppression (grade 1-2, WHO). A positive response (complete or partial tumour remission) was observed in 94% of patients with primary tumours and in 50% of cases with cervical lymph node metastases. The reduction in tumour size often precluded the need for surgery and the cycles of chemotherapy were followed only by target radiotherapy for the tumour residue.

Hydroxyapatite as metallic prosthesis coating: preliminary clinical experience.

The authors report the radiographic results of 65 An. C.A. prosthetic stems coated with hydroxyapatite and followed-up at least 24 months after implantation. A comparison with a homogeneous group of aluminum-coated An.C.A. stems showed that hydroxyapatite-coated stems are characterized by better osteointegration, with a clearly inferior incidence of radiolucent lines at the bone/prosthesis interface. Macroscopic observation and histologic examination carried out on two stems removed because of persistent pain to the thigh revealed partial resorption and fragmentation of the coating. The authors believe that this phenomenon, the object of other observations reported in the literature, may indicate the reduced stability of the coating in the long run, and as such further in-depth study is required.

Anterior extraoral surgery to the upper cervical spine.

STUDY DESIGN: A series of 10 patients surgically treated with prevascular or retrovascular extraoral retropharyngeal approach to the upper cervical spine is examined. OBJECTIVES: In orthopedic surgery, retropharyngeal approach may replace the transoral surgery, obviating the risks of infection and the uncomfortable postoperative course of cases in which median labiomandibular glossotomy was used to accomplish complex bone reconstruction. SUMMARY OF THE BACKGROUND DATA: The transoral approach is reported in literature as the classical anterior access to the upper cervical spine that provides direct exposure for anterior decompression of the spinal cord. The risks, the surgical limits, and the postoperative difficulties of transmucosal access suggest the use of an anterior extraoral retropharyngeal approach in orthopedic surgery. METHODS: The series includes four neoplastic lesions (osteoma, aneurismal bone cyst, giant cell tumor, solitary metastasis), three retropharyngeal ossifications resulting from diffuse idiopathic skeletal hyperostosis, and a single case of os odontoideum, craniocervical malformation, and postlaminectomy kyphosis. RESULTS: At follow-up evaluation, all patients achieved a satisfactory outcome, with good clinical and radiographic results; nasotracheal intubation obviated the need for tracheostomy. The wide surgical exposure allowed reconstruction with iliac strut bone grafts and internal fixation in six patients, avoiding the need of a halo device. The only complications were four instances of transient palsies of the marginal mandibular branch of the facial nerve. CONCLUSIONS: In the anterior surgery of the upper cervical spine, the prevascular approach allows a wide surgical exposure, with visualization similar to that obtained with median labiomandibular glossotomy. The retrovascular approach is indicated in selected cases, such as tumor adjacent to the vertebral artery and C1-C2 arthrodesis with bilateral transarticular screws according to Barbour.

[Dynamic study of the distal radioulnar joint with computerized tomography]. / Studio dinamico dell'articolazione radio-ulnare distale con Tomografia Computerizzata.

The authors describe a CT technique which allows the dynamic study of the inferior radioulnar joint. The examination consists of 4 CT slices, three of them acquired at the same level-i.e., the radioulnar joint- in the prone, intermediate and supine positions, respectively. The last slice is acquired, with the patient in the prone position, at the base of the styloid process where the triangular fibrocartilage is demonstrated. The distal radioulnar ligaments are not directly visible. Nineteen patients complaining of painfully impaired pronation and supination because of previous trauma (11 Colles fractures, 7 distortions and 1 Galeazzi lesion) were examined with this technique. In all patients, both wrists were studied to obtain normal parameters. The radioulnar joint was evaluated superimposing a draft on the dynamic images, which demonstrated that, in healthy limbs, during movement the ulnar epiphysis is always contained between two parallel lines drawn on the volar and dorsal surfaces of the radial epiphysis, respectively. It was also confirmed that supination is possible up to 110-135 degrees from the support plane. CT demonstrated different causes of impaired movements in the affected joints: in 12 cases some fibrous density tissue was seen at the ulnar epiphysis on the volar aspect and considered to be the evolution of a traumatic hematoma; 6 patients presented dorsal subluxation of the ulna during movement; finally, volar subluxation was detected only in one case. In 6 patients the triangular fibrocartilage was detached; in 1 patient an intraarticular fluid collection was demonstrated. In 3 patients CT detected no abnormalities. The fibrous tissue is responsible for impaired movements and causes the detached triangular fibrocartilage to shrink. The authors believe that this simple CT technique can yield useful pieces of information for accurate surgical planning.

Cerebral visual impairment in periventricular leukomalacia: MR correlation.

PURPOSE: To evaluate the involvement of central visual pathways in cases of periventricular leukomalacia, and to correlate the neuroradiologic findings with the degree of visual acuity. METHODS: The MR brain examinations of 27 preterm children affected by cerebral palsy resulting from periventricular leukomalacia and without significant ophthalmologic lesions were reviewed retrospectively to search for possible involvement of the optic radiations and/or of the calcarine cortex. The data were compared with the degree of visual acuity estimated by means of the Teller Acuity Cards test. RESULTS: Seventeen (63%) of the 27 patients had cerebral visual impairment, which correlated strongly with MR lesions. Quantitative reduction and signal hyperintensity of the peritrigonal white matter and atrophy of the calcarine cortex were present in the more severe cases. In two blind patients, an altered MR signal was detected in the lateral geniculate bodies. CONCLUSION: This study clearly establishes a relationship between specific MR findings and visual impairment in children with periventricular leukomalacia. The finding of hyperintensity in the lateral geniculate bodies was interpreted as an axonal reaction. MR imaging is useful for detecting potential visual impairment and for improving clinical diagnosis.

[High-dose carboplatin superselective intraarterial chemotherapy in advanced head and neck cancer]. / La chemioterapia intraarteriosa neo-adiuvante superselettiva con carboplatino ad alte dosi nei tumori avanzati cervico-facciali.

Advances in vascular radiology techniques for superselective transfemoral arterial infusion prompted us to evaluate the effects of high-dose rapid regional carboplatin infusion for patients with advanced head and neck squamous cell carcinomas. Twenty untreated patients received three infusions of carboplatin (300-350 mg/m2) every 2 weeks with this method. All the infusions were performed without any complication. Treatment was well tolerated, with moderate (Grade 1-3 WHO) local toxicity (stomatitis, dermatitis and alopecia) and minimal (Grade 1-2 WHO) myelosuppression. The total response index (complete response plus partial response) was 94% for primary tumors and 50% for neck metastases. Neoadjuvant chemotherapy employing superselective rapid infusion of high-dose carboplatin is a feasible, relatively nontoxic, effective technique and may have important applications in multimodality therapy of untreated patients with advanced head and neck cancer.

Fracture of the ceramic epiphysis in hip arthroplasty.

Between November 1985 and October 1993, a total of 694 ceramic-ceramic hip arthroplasties were implanted; up until 1987 the alumina used in the first 82 cases was Ostalox, produced by IMEC of Caravaggio, characterized by poor control of the size of the crystals; after 1987 Biolox alumina of the Feldmhule company was used in 612 cases. Fracture of the ceramic head occurred in 2 cases; in both patients ceramic was of the Ostalox type, meaning a 2.4% incidence of fracture; up until the present none of the 612 Biolox heads has presented this complication.

Internal carotid occlusion associated with migraine syndrome: a case study of a 22-year-old female.

Migraine and migraine-like headaches are sometimes associated with acquired types of carotid artery disease. We examined a 22-year-old female suffering from periodic migraine, sometimes with "atypical" features. Color Flow Duplex Sonography revealed an occlusion of the right internal carotid artery (ICA) and a possible severe stenosis of the cervical segment of the left ICA. Digital Subtraction Angiography combined with Angio-Magnetic Resonance Imaging and Echographic Imaging suggested the possibility of a fibromuscular dysplasia involving both ICAs. It is suggested that some atypical features of headache could represent symptoms of a carotid pathology.
