[Diagnosis of spinal diseases by MRI]. / Irm et rachis.

For a long time the imaging diagnosis of spine disease was based on conventional radiology (plain radiography, myelography and arteriography). The recent employment of MRI had changed the study of spine disease thanks to an excellent contrast and a multiplanar approache. In fact, nowadays MRI is the most sensible technic for a combined study of spine container and contents and medullar tissue.

[Primitive pleural hydatid cyst: case report]. / Kyste hydatique pleural primitif: a propos d'une observation.

Even in endemic countries, the primitive pleural hydatid cyst is exceptionnal and it's very difficult to distinguish from other pleural and parietal cystic masses all the more the immunologic tests are negative. We report the case of a primitive pleural hydatid cyst diagnosed in 43 years old man. Throug this case, imaging features are emphasized.

Determination of serum adenosine deaminase and xanthine oxidase activity in Kangal dogs with maternal cannibalism.

AIM: Kangal dogs, known as guard dogs in many countries of the world, have been found to eat their own puppies during their first 24 h following birth, which is called as maternal cannibalism. Adenosine deaminase (ADA) and xanthine oxidase (XO) are important enzymes for purine metabolism. In this study, the aim is to evaluate ADA and XO activities in Kangal dogs with maternal cannibalism. MATERIALS AND METHODS: The material of the study consists of the blood sera of Kangal dog breed with and without maternal cannibalism in the breeders around Sivas city and its districts. ADA and XO activities in blood serum of these animals were investigated by spectrophotometric method. RESULTS: ADA activities in Kangal dogs with maternal cannibalism were increased to the control group without maternal cannibalism (p<0.01). CONCLUSION: Postnatal measurement of ADA activity in dogs may be useful in assessing maternal cannibalism.

[Adrenal gland hemangioma: a case report]. / Hémangiome surrénalien: à propos d'un cas.

Hemangioma is a benign vascular tumor composed of angioblastic cells. The adrenal gland localization is very rare, with only fifty cases reported in literature. We report a case of adrenal gland hemangioma diagnosed in a 55-year-old woman who presented a cervical neoplasm. The non-specific imaging features, the tumor size and the clinical context led to mandatory surgical resection. The pathological examination established the diagnosis of adrenal gland hemangioma.

[MRI and pituitary adenoma]. / IRM et adénomes hypophysaires.

Pituitary is the most important gland of the organism which can be affected by many diseases, especially by adenomatous processes. Classically macroadenoma, microadenoma and picoadenoma are described, according to the size of the pituitary adenoma. The diagnosis of microadenoma was long considered a highly difficult task and that of picoadenoma was impossible by computed tomography. Recently, the high resolution of multiplanar MRI has enabled the diagnosis of microadenomas measuring less than 3 mm (picoadenoma). For macroadenoma, MRI not only contributes to diagnosis but is particularly important to assess the extension and to detect possible complications. The aim of our study is to illustrate MRI features in pituitary adenoma.

[Cavernous hemangioma of the breast: a case report]. / Hémangiome caverneux du sein: à propos d'un cas.

Cavernous hemangiomas of the breast are uncommon. Clinical diagnosis is rather difficult. Generally there are coincidental microscopic findings. We present a case of a 67-year-old woman which commenced as a 6 cm palpable mass of the right breast. The use of mammography, ultrasound and MRI facilitate diagnosis. Large surgical excision of the lesion was performed and histology allowed to find a cavernous hemangioma without cellular atypia.

[Hemoperitoneum secondary to the rupture of superficial veins of a uterine leiomyoma]. / Hémopéritoine secondaire à la rupture des veines superficielles d'un léiomyome utérin.

The most frequent cause of gynaecological hemoperitoneum is ruptured ectopic pregnancy. An uncommon cause of hemoperitoneum is rupture of uterine leiomyoma. We report one case of massive intraperitoneal hemorrhage and hypovolemic shock due to ruptured uterine leiomyoma vessels. The patient was treated with myomectomy and the postoperative course was uneventful. These case suggest that massive intra peritoneal hemorrhage associated with uterine leiomyoma should be considered in women with hypovolemic shock and pelvic mass.

[Bone anomalies in von Recklinghausen disease]. / Anomalies osseuses dans la maladie de Von Recklinghausen.

28 cases of neurofibromatosis are reported. Principals bone anomalies are reviewed. The skeletal manifestations are numerous and varied. These anomalies interest specially cranial vault, spheno-orbital area and vertebral spine. It is imperative to keep in mind skeletal manifestations because neurologic and cutaneous signs can be absent.

[Subcapsular hematoma complicating acute pyelonephritis]. / Hématome sous-capsulaire compliquant une pyélonéphrite aiguë.

Spontaneous subcapsular renal hematoma is rare and essentially associated with malignant, or benign tumor vascular diseases, inflammatory processes. In few cases, no cause was detected. We observed one additional case in a diabetic women. She presented fever, and bilateral flank pain. Ultrasonography showed bilateral subcapsular hematoma. Computed tomography confirmed these findings and demonstrated multiple area of acute focal pyelonephritis.

[Pyogenic abscess of the psoas]. / Les abcès à pyogènes du psoas.

11 cases (7 primary and 4 secondary) of pyogenic psoas abscesses are reported. In all cases Staphylococcus aureus was isolated on blood culture or pus drained under ultra-sonographic control. US is very useful for diagnosis and the follow up of psoas pyogenic abscesses. Percutaneous aspiration and drainage of psoas abscesses under ultrasonographic control combined to antibiotherapy is an effective therapeutic procedure. Our experience suggests that antibiotherapy alone is an effective therapy of presuppurative pyogenic psoas abscesses and even in collected and non complicated primary psoas abscesses.

[Abdominal actinomycosis. Report of 4 clinical cases studied with radiography]. / Actinomycose abdominale. A propos de 4 observations radiocliniques.

We report 4 cases of pathologically proven abdominal actinomycosis. US and CT demonstrated an infiltrative abdominal mass with ill-defined margins and heterogeneous enhancement after IV contrast. The ileo-cecal region was involved in one case; the mass appeared following cholecystectomy and recurred 3 years after surgical resection in one case; and no predisposing factor was identified in the 2 other cases. In one of these, recurrence was observed 12 years after the first episode. Actinomycosis must be included in the differential diagnosis of invasive abdominal lesions with "malignant" appearance.

[Ultrasonographic aspects of kidney pelvis tumors associated with infectious hydronephrosis of lithiasic origin]. / Aspects échographiques des tumeurs pyéliques sur hydronéphrose infectée d'origine lithiasique.

The ultrasonographic findings of 4 patients with surgically confirmed urothelial tumors associated with calculic pyonephrosis are presented. All the involved were markedly enlarged and hydronephrotic with obstructive calculi, stigmata of pyonephrosis and, an echoic pelvic mass, extending in calyceas in 2 cases. The sonographic appearance correlated well with the gross pathological findings. The histological types were 2 squamous cell carcinomas, 1 adeno-squamous cell carcinoma and 1 transitional carcinoma. The chronic calculic irritation was proved to induce squamous and glandular metaplasia. The subsequent squamous carcinoma and adenocarcinoma were documented in the literature. The preoperative diagnosis of the associated tumor was rarely done. The sonographic features reported are highly suggestive of urothelial tumor and may lead to an accurate preoperative diagnosis.

[Adrenal tumors in Beckwith-Wiedemann syndrome. Apropos of a case]. / Tumeurs surrénaliennes dans le syndrome de Beckwith-Wiedemann. A propos d'un cas.

A case of a neonate with Beckwith-Wiedemann syndrome is presented. Antenatal sonography detected a right adrenal cystic mass confirmed in post-natal which resolved spontaneously within 1 month. The child developed an adrenal adenoma detected by abdominal sonography at six months of surveillance. The authors review the different adrenal lesions possibly associated with Beckwith-Wiedemann syndrome and specially the pseudo-tumorous lesions. The value of abdominal sonography in the neonatal periods and in the surveillance of children with Beckwith-Wiedemann syndrome is emphasized.

[Radioclinical profile of cardiopericardial hydatid: report of 17 cases]. / Profil radioclinique du kyste hydatique cardiopéricardique: à propos de 17 cas.

Hydatid cysts concerning the heart are rare, accounting for 0.5 to 2% of all hydatic sites. The risk of serious complications in this location makes rapid diagnosis and surgical treatment essential. The aim of our study is to clarify the role of imaging in the diagnosis of the disease and to propose an adequate strategy. We report on 17 patients who underwent surgery for cardiopericardial hydatid cyst in the cardiovascular and thoracic unit of Sahloul hospital in Sousse from January 1988 to December 1998. Clinical investigation included in all cases chest X ray, ECG and ultrasonography (US). A computed tomography (CT) scan was performed in 14 cases, magnetic resonance imaging in three cases, transesophageal US in five cases, and coronary angiography in fsix cases. Examination for other hydatic sites was realized in all cases, and brain CT was performed in four cases. The hydatid cyst was variably localized in the left ventricle wall (five cases), the right ventricle (five cases), the pericardium (five cases), the interventricular septum (four cases), the right auricle (one case) and the left auricle (one case). The existence of other cardiac hydatid sites was found in 12 cases. All patients underwent surgery. Outcome was favorable in 14 cases, with a mean of 3 years and 5 months survey. Three patients died. The combination US-CT scan allowed a precise topographical inventory, reducing the need for MRI to the complicated cases and to the rare cases of inconclusive results by US-CT scan.

[Right tracheal bronchus associated with tuberculosis pneumonia. A case report]. / Bronche trachéale droite associée à une lobite segmentaire tuberculeuse. A propos d'un cas.

Right tracheal bronchus is a rare almost always asymptotic congenital malformation. We report a case of right tracheal bronchus associated with pneumonia tuberculosis of the apical segment of the upper right lobe. We describe the characteristic of this malformation and stress the role of computed tomography scan to detect these anomalies.

[Neurosarcoidosis as the first manifestation of sarcoidosis: diagnosis difficulty. A case report]. / Problème diagnostique d'une neurosarcoïdose révélatrice. A propos d'un cas.

Clinically apparent involvement of the nervous system occurs in a relatively small number of patients with sarcoidosis. The diagnosis of neurosarcoidosis is often difficult and particularly in patients who lack either pulmonary or systemic manifestations of sarcoidosis. Furthermore clinical and imaging features of neurosarcoidosis are extremely variable. We report a case of neurosarcoidosis which had been considered and treated at first as tuberculosis. Only the occurrence, two years later, of pulmonary manifestations of sarcoidosis enabled the diagnosis.

Vertebral metastases from intracranial meningioma.

Meningioma rarely gives rise to metastases outside the brain and meninges. We report here a case of a patient who was treated for anaplastic brain meningioma with surgery and fractionated radiation therapy without any recurrence until 5 years after the operation, when she developed vertebral metastases.

The importance of myeloperoxidase enzyme activity in the pathogenesis of Crimean-Congo haemorrhagic fever.

Crimean-Congo haemorrhagic fever (CCHF) is a disease with a severe course including acute viral haemorrhagic fever, ecchymosis, thrombocytopenia, hepatic function disorder and high mortality. Myeloperoxidase (MPO) is an enzyme located in neutrophil granulocytes and plays an important role in the destruction of phagocytosed micro-organisms. The aim of this study was to analyse MPO enzyme activity in CCHF cases compared with a control group. A total of 47 randomly selected CCHF patients admitted to the Department of Infectious Diseases of Cumhuriyet University Hospital in Sivas, Turkey, were studied, and as a control group, 41 age- and sex-matched individuals without any systemic disease were included in this study. MPO enzyme activity was measured in plasma and leukocytes for both groups by the ELISA method. MPO plasma and MPO leukocyte values were calculated as 57.62 ± 8.85 and 44.84 ± 9.71 in CCHF patients, and 0.79 ± 0.29 and 0.49 ± 0.11 in the controls, respectively. MPO enzyme activity was statistically significantly higher in patients with CCHF when compared to the control group. In conclusion, MPO enzyme activity is directly related to the activation of phagocytic leukocytes, and increases in both the plasma and leukocytes in CCHF patients. The increase of the MPO enzyme activity in leukocytes due to viral load leads to the destruction of the leukocyte. It is thought that MPO enzyme activity in plasma was higher in CCHF patients due to the destruction of leukocytes. MPO enzyme activity may be important in terms of the prognosis in patients with CCHF; however, more extensive studies are required on this subject.
