Review Case Reports
[Intracranial meningioma of an infant: a case report].
An 11-month-old male infant with intracranial meningioma is presented. Intracranial meningiomas in infancy under the age of 1 year are extremely rare, and only 22 cases have been reported previously. The authors reviewed the clinical and pathological findings of these meningiomas including our case. ⋯ Histological diagnosis was of fibroblastic meningioma. He was discharged two weeks after the operation without any neurological deficits. Several characteristic features of meningiomas in infant under 1 year old were drawn from the review of literature in comparison with those of meningiomas in adult. 1) Predominant sex was male (16/23). 2) All meningiomas developed in the supra-tentorium. 3) Eight of 18 tumors being described did not have the dural attachment. 4) Nine of 16 tumors showed cyst formation. 5) The most cases were histologically diagnosed benign (17 of 22), and 15 cases was fibroblastic meningioma.

Liver abscess is a rare complication following the ventriculoperitoneal (V-P) shunt operation. There has been only one case reported in the literature. We present a case of liver abscess developed about 3 months after V-P shunt operation. ⋯ It is considered that the formation of the liver abscess seems to be caused by the focal injury to the liver surface by the insidiously infected peritoneal tube with St. epidermidis, and by the decrease in systemic resistance to infection. Percutaneous aspiration and drainage under the guidance of abdominal computed tomography or ultrasonography are very useful and efficient for the diagnosis and the treatment of liver abscess. When patients show signs of infection to the V-P shunt, we should remove the shunting system and place a new external ventricular drainage, and institute a V-A shunt after confirming negative cultures of the CSF.

We report a rare case of traumatic spinal subarachnoid hematoma with Brown-Séquard syndrome following hyperextension injury. A 43-year-old man was admitted to our hospital four days after hyperextension cervical injury complaining of nuchal pain, left hemiparesis and dysesthesia of the left arm. On the third hospital day, neurological examination revealed left C2,3 level Brown-Séquard syndrome. ⋯ Brown-Séquard syndrome caused by spinal subarachnoid hematoma was not found on the literature either. So we believe that this is the first report of case of such lesion. The mechanism of subarachnoid clot formation on hyperextension injury may be due to transient dislocation of the spine with tearing of the anterior longitudinal ligament or to crushing of the cord between the ligamentum flavum, which bulged forward on hyperextension, and the posterior aspect of the vertebral body.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of non-neoplastic pineal cyst with Parinaud's syndrome is presented. A 54-year-old woman was admitted to the department of neurosurgery. Fukui Medical School on October, 1985, complaining of the paralysis of upward gaze. ⋯ On December 27, the patient was discharged in excellent condition. Non-neoplastic small cysts which do not cause an enlargement of the pineal body are common incidental findings at autopsy, whereas large cysts which cause symptoms due to compression of the corpora quadrigemina and the production of internal hydrocephalus are rare. In this paper, non-neoplastic pineal cyst is discussed.

A rare case of idiopathic brain stone with psychomotor epilepsy is reported. On December 9, 1982, a 29-year-old man with 18 years' history of psychomotor epilepsy was admitted to our neurosurgical service. He had no history of neonatal asphyxia, trauma or other neurological diseases. ⋯ Histopathological examination demonstrated thick collagen fibers and gliosis around the stone, and diagnosis of idiopathic brain stone was made. We reviewed five previously reported cases. We also emphasized an epileptogenicity of idiopathic brain stone and indication of surgical excision which may result in an excellent control of epilepsy.
