RESUMO
Struthers' ligament syndrome is a rare cause of median nerve entrapment. Bilateral compression of the median nerve is even more rare. It presents with pain, sensory disturbance, and/or motor function loss at the median nerve's dermatomal area. The authors present the case of a 21-year-old woman with bilateral median nerve compression caused by Struthers' ligament. She underwent surgical decompression of the nerve on both sides. To the authors' knowledge, this case is the first reported bilateral compression of the median nerve caused by Struthers' ligament. The presentation and symptomatology of Struthers' ligament syndrome must be differentiated from median nerve compression arising from other causes.

OBJECTIVE: A case of postoperative tension pneumocephalus after low basilar trunk aneurysm clipping is presented. To our knowledge, this is the first case of isolated prepontine tension pneumocephalus. BACKGROUND: A 63-year-old woman was admitted for repair of a basilar aneurysm that had caused a subarachnoid hemorrhage. She was cooperative and partially oriented. According to Hunt & Hess classification, she was considered Grade III. METHOD: The aneurysm was clipped, using a right lateral suboccipital craniectomy with the patient in the sitting position. In the early postoperative period, she had no new neurological deficit. However, 2 hours later the patient became lethargic and unresponsive to verbal commands. Emergency CT scan revealed an isolated prepontine tension pneumocephalus with prominent posterior displacement of the pons. She was immediately taken back to surgery. Upon incision of the dura mater, air could be heard escaping under pressure from the posterior fossa cavity. The clip was in its proper position and all arteries were patent. Spontaneous respiration and pupil reflexes returned soon after surgery, but she remained unconscious and died 3 days later. CONCLUSION: We believe that this death was directly attributable to the tension pneumocephalus and the distortion of the pons. Postoperative prepontine tension pneumocephalus, although this is an extremely rare condition, should be considered if a patient deteriorates after basilar aneurysm surgery in the sitting position.

We report two cases of acute cervical angina and ECG changes induced by anteflexion of the head. Cervical angina is defined as chest pain that resembles true cardiac angina but originates from cervical discopathy with nerve root compression. In these patients, Prinzmetal's angina, valvular heart disease, congenital heart disease, left ventricular aneurysm, and cardiomyopathy were excluded. After all, the patient's chest pain was reproduced by anteflexion of head, at this time, their ECGs showed nonspecific ST-T changes in the inferior and anterior leads different from the basal ECG. ECG changes returned to normal when the patient's neck moved to the neutral position. To our knowledge, these are the first cases of cervical angina associated with acute ECG changes by neck motion.

BACKGROUND: Solitary brain stem abscess is a rare condition with high mortality and morbidity. These lesions were considered to be invariably fatal before 1974 when advanced diagnostic tools were not available. Recently, the diagnosis and prognosis of brain stem abscesses have been modified by the introduction of modern radiological tools, and several patients with a favorable outcome have been reported since then. Because the pons is the most common site of the abscesses, involvement of the sixth and seventh nerves is frequent. The midbrain is the second most likely location, and medullary abscesses are distinctly rare. Treatment of a brain stem abscess includes medical therapy alone, open microsurgical intervention, or stereotactic aspiration. CASE REPORT: We report a case of a 7-year-old girl with a solitary brain stem abscess. Her neurological examination revealed involvement of the cranial nerves and pyramidal tracts. Microsurgical exposure and aspiration of the abscess resulted in rapid improvement in her neurological condition and radiological resolution of the lesion. We discuss this uncommon case to draw attention to the importance of early diagnosis and adequate treatment, and we review the relevant literature.

Trauma to the brain or calvaria may cause some cranial nerve damage. This may be transitory or permanent. Occipital condyle fracture (OCF) is a rarely encountered pathology not easily diagnosed by routine clinical and radiological evaluation and one of the causes of lower cranial nerve disability. Frequently, the hypoglossal nerve is involved. Here we present two cases of OCF caused by motor vehicle accidents. Both of the patients complained of dysphagia and voice disturbance. After detailed neurologic and radiologic evaluation, they were diagnosed with OCF. They were both treated conservatively. OCF as a cause of lower cranial nerve damage is rarely reported. Since it is hard to diagnose OCF by routine cranial and cervical evaluation, detailed radiological study in suspected cases is a must. Since one of our patients was admitted 6 years after the trauma, this article is also noteworthy as a report on radiological changes of the OCF.

Pyknodysostosis is a rarely encountered disease. It is characterized by abnormal facial development, fragility of the bones with relatively mild trauma, cranial abnormalities including widely opened sutures and fontanels frontal bossing, wrinkled skin, finger and nail abnormalities. In the literature, pyknodysostosis was reported only as case reports. Here, we describe a pyknodysostotic child with a bilateral parietal epidural hematoma, caused by a relatively mild head trauma. He was operated on, and the hematoma was evacuated through two different parietal craniotomies. We reported this case, since pyknodysostosis is a rare disease, and our case is the first one who had a surgical intervention as well as being the first with an epidural hematoma in pyknodysostosis.

Cushing's disease (CD) in adolescence and childhood is a rare pathology and has some different clinical and therapeutic characteristics than in adults. We report 3 cases treated surgically, with the diagnosis of CD. Their common complaints were short stature and obesity. Endocrinological investigations and radiological evaluation pointed out the diagnosis of CD for all children. They were operated on by the transsphenoidal route, and adenoma resection was performed. Histopathologic and immunohistochemical examination of the tissue specimens confirmed the diagnosis of CD. Long-term follow-up demonstrated weight loss and increase in height.

AIM: The aim of this study is to retrospectively assess the complications and result of cases that underwent open surgery or endoscopic releasing for carpel tunnel syndrome. METHOD: A total of 50 cases of carpel tunnel syndrome, 30 of whom underwent endoscopic release using the biportal extrabursal technique described by Chow, and the other 20 that underwent open surgery were included in the study. Average age of the cases was 41 (24 - 62), 44 of them were females and 6 males. RESULTS: Follow-up examinations of the patients at the first and third month after operation revealed no limitation of activity in 40 (80 %) cases, minimal limitation in 4 (8 %), moderate limitation in 5 (10 %) and significant limitation in 1 (2 %). Among the group that underwent endoscopic release, as a major complication, the median nerve was almost totally cut in a patient undergoing endoscopic release. During the same operation setting perifascicular neurorrhaphy was done. Fourth and fifth digital nerve lesions occurred in three cases. Among the group that underwent open surgery fourth and fifth digital nerve injury occurred in one case, and in another case severe inflammation requiring reoperation occurred. CONCLUSION: Before intervention, cases of carpal tunnel syndrome should be examined well as regards which technique to use. Experience of the surgeon with the technique to be used should also be taken into consideration. Endoscopic carpal tunnel releasing, though a relatively easier procedure, leads to neurovascular injuries more frequently than open surgery; thus open surgery appears to be safer.

21 patients with gunshot wounds were retrospectively evaluated. They were 19 male and 2 female, age range was 9-24. All of the patients underwent a plain x-ray and computed tomography evaluation. 9 patients had intracerebral hematoma, 4 had subdural hematoma, 1 had epidural hematoma and 1 had intraventricular hematoma. 9 patients were observed to have bullet in the cranium. All the patients with glasgow coma scale 3-5 at the admittance died. 15 patients underwent surgical treatment. 3 patients had cerebrospinal fluid fistula postoperatively and underwent reoperation. Extensivity of the lacerated brain, localization of the lesion and the glasgow coma scale at the admittance affect the outcome in gunshot wounds.

A 6-year-old girl presented with visual deterioration that had progressively worsened over 2 months. MR imaging revealed a sellar, para- and suprasellar lesion. Subtotal tumor resection was performed. Histopathological diagnosis was glioblastoma of the optic chiasma. Chiasmatic glioblastoma is rare in adults and extremely uncommon in children. Surgical resection implies a risk of severe endocrinologic and ophthalmologic complications.

This study was designed to analyze the effect of early indomethacin on the lipid peroxidation after spinal cord injury in rats. The use of anti-inflammatory drugs to affect delayed and secondary injury after trauma to the spinal cord has now become a matter of standard clinical practice. However, spinal cord injury remains an enormous clinical problem and research that may lead to improved treatment is to be encouraged and commended. Three experimental groups consisting of 40 rats each were formed. Using microsurgical technique, total laminectomy between T5 and T10 was performed. Spinal cord injury was achieved with an epidural aneurysm clip, and pharmacological treatment immediate after the injury was performed by injecting indomethacin intraperitoneally (i.p.) at a dose of 3 mg/kg to indomethacin-treated group. The three main groups were divided into subgroups of 8 rats each. It was planned to stop the biochemical reactions at a different time in each of these subgroups, by the application of liquid nitrogen to the spinal cord and paravertebral structures at the end of the 1st, 15th, 30th, 60th, and 90th minutes. All the spinal cords were removed and protected from further reactions by immersing in the liquid nitrogen tank. The lipid peroxidation levels were assessed by determining thiobarbituric acid reactive substances formation. The results of the study showed that the administration of 3 mg/kg indomethacin immediately after spinal cord injury induces lipid peroxidation to a significant degree (p<0.05 one-way ANOVA and Tukey HSD tests) when compared to the saline-treated group. This result suggests that early posttraumatic indomethacin treatment may be harmful in spinal cord injury.

Intradiploic meningioma, which may be classified as a subgroup of intraosseous meningioma, is a rarely encountered disorder. To date, less than 10 cases have been reported. Here, we report a case of fronto-orbitonasal intradiploic meningioma. A 12-year-old female with exophthalmos and diplopia was operated on for a cranial intradiploic mass lesion. Histopathological evaluation of the specimen confirmed the diagnosis of intradiploic psammomatous meningioma. Her exophthalmos did not change, but the diplopia disappeared. This case is unique in that it is an extensive case of intradiploic meningioma of the orbital roof and frontal base in a child. Intradiploic meningiomas generally are of psammomatous type. Especially tumors adjacent to the orbita cause exophthalmos; cases located on the other side of the calvarium may not cause any symptom or sign other than headache or sometimes a mass on the scalp. Treatment, as with meningiomas located in the intracranial cavity, is total resection of the lesion.

The aim of this study was to describe a possible variant of encephalo-craniocutaneous lipomatosis syndrome. Three cases of congenital infiltrating lipomatosis of the face, associated with cutaneous, subcutaneous, and cerebral abnormalities, are presented. This neurocutaneous syndrome appears very similar to encephalo-craniocutaneous lipomatosis syndrome but lacks the typical eye lesions.

In order to investigate the pathophysiology of the tethered cord syndrome, a few experimental models have been developed and used previously. In this study, the authors present a new experimental model to investigate the biochemical, electrophysiological, and histopathological changes in the tethered spinal cord syndrome. A model was produced in guinea pigs using an application of cyanoacrylate to fixate the filum terminale and the surrounding tissue to the dorsal aspect of the sacrum following 5-gram stretching of the spinal cord. The experiments were performed on 40 animals divided into two groups. The responses to tethering were evaluated with hypoxanthine and lipid peroxidation, somatosensory and motor evoked potentials, and transmission electron microscope examination. The hypoxanthine and lipid peroxidation levels significantly increased, indicating an ischemic injury (p < 0.01). The average hypoxanthine level in the control group was 478.8 +/- 68.8 nmol/g wet tissue, while it was 651.2 +/- 71.5 nmol/g in the tethered cord group. The lipid peroxidation level in group I was 64.0 +/- 5.7 nmol/g wet tissue, whereas it was 84.0 +/- 4.7 nmol/g in group II. In the tethered cord group, the latencies of the somatosensory and motor evoked potentials significantly increased, and the amplitudes decreased. These changes indicated a defective conduction in the motor and sensorial nerve fibers. In the transmission electron microscopic examinations, besides the reversible changes like edema and destruction in the gray-white matter junction, irreversible changes like scarcity of neurofilaments and destruction in axons and damage in myelin sheaths were observed. We consider that this work can be used as an experimental model for tethered cord syndrome.
