Ossified thoracic spinal meningioma in childhood: a case report and review of the literature.

Spinal ossified meningiomas are extremely rare. This is a report of a study on a 15-year-old boy with thoracic spinal ossified meningioma. The meningioma was resected totally. Histopathological examination revealed a transitional meningioma (psammomatous+meningothelial). Immunohistochemically, Ki 67 antibody was applied but no positive staining was present. The surgical and pathological aspects of spinal ossified meningiomas were reviewed.

Posttraumatic isolated infarction in the territory of Heubner's and lenticulostriate arteries: case report.

A 12 year old male had a secondarily generalized epileptic seizure and a subsequent right hemiparesis with fasciobrachial predominance after a closed head injury. His seizures responded to antiepileptic drug therapy immediately. Computerized tomographic scanning and magnetic resonance imaging showed an acute infarct of the head of the left caudate nucleus, indicating the isolated occlusion of the left recurrent artery of Heubner and lateral lenticulostriate arteries. Pathologies leading to vasculitis and embolism were also looked for, but no finding of associated systemic disease could be disclosed. We present this case since posttraumatic infarction in the territory of the deep perforators such as recurrent artery of Heubner and lateral lenticulostriate arteries are exceptionally rare conditions especially in this age group.

Giant thrombosed aneurysm of the vertebral artery in childhood: an extremely rare case.

In childhood, a significant proportion of giant aneurysms usually occur at the vertebrobasilary system. Nonetheless, giant totally thrombosed aneurysm which only involves the vertebral portion of the vertebrobasilary system is very rare. Up to this time, in childhood, a few giant aneurysm originating from vertebral artery have been reported, and to our knowledge only one case was reported to be totally thrombosed. The enlargement tendency of totally thrombosed aneurysms and management of these cases are still controversial. Thus, diagnosis and follow-up of cases where a radical approach could not be performed require a multi-modality radiologic approach. In this study, we reported a case of angiographically occult giant thrombosed vertebral artery aneurysm, which is extremely rare, and discussed the importance of CT and MRI in evaluation of these patients before surgical treatment.

Delayed traumatic intracerebral hematoma.

Although delayed traumatic intracerebral hematomas (DTICHs) have been frequently reported since 1970, the time interval from trauma to hemorrhage and diagnosis has not been well defined. Eight patients with DITCH were found among 1,320 head-injured patients admitted to the neurosurgical service through the emergency department from March 1989 to March 1990. The mean time interval between initial and follow-up CT scan was 22 h. The mean time interval between initial trauma and diagnosis of DITCH was 24 h. One patient was diagnosed incidentally by magnetic resonance imaging. Three patients underwent operation and five patients were managed conservatively. Three patients died, resulting in a case mortality rate of 37.5%. The time interval for DTICHs' development and pitfalls in its diagnosis were discussed.

Endobronchial tuberculosis simulating foreign body aspiration.

A case of sudden onset of severe respiratory distress is reported. Appropriate clinical and roentgenologic findings suggested foreign body aspiration. The foreign body was removed by fiberoptic rigid bronchoscope. Bronchoscopic, histopathologic, and microbiologic findings revealed that the foreign body was a granulomatous mass originating from endobronchial tuberculosis.

Monitoring cerebral blood flow during intracranial operations: an intravenous injection method.

A method of measuring cerebral blood flow during neurosurgery is described. It is an adaptation of the standard 133Xe intravenous injection method, with computation restricted to data collected over the first 3 min. In addition to a theoretical presentation of the method and an analysis of the effect of residual 133Xe activity when sequential runs are performed in close approximation, the technique is validated experimentally by comparison with intracarotid 133Xe injection in baboons.

Diluted yogurt (ayran) versus water in dissolving oral rehydration salts.

Seventy-six children with gastroenteritis were treated with oral rehydration salts dissolved in ayran (diluted yogurt), and eighty patients were treated with oral rehydration salts dissolved in water. The patients whose ages ranged between three and twelve months accepted both solutions equally. However, the acceptance of the ayran-based solution was significantly greater than WHO's salt solution in the patients whose ages ranged between one and four years. It is proposed that ayran be used to dissolve oral rehydration salts in the treatment of diarrhea since it is more palatable and easily acceptable by children.
