Ependymomas accounts for about 2%–6% of CNS and 60%–70% of spinal cord tumors. Several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. In spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. This report presents a case of giant cell ependymoma...

137 The paraganglion system, a component of the neuroendocrine system, comprises the adrenal medullae and the extra-adrenal paraganglion system. Tissues of the extra-adrenal system have been classified into 4 groups: branchiomeric (associated with arterial vessels and cranial nerves derived from the branchial arches); intravagal; aorticosympathetic; and visceral-autonomic (including cardiac atr...

Lumbosacral lipoma is reported to occur in 4-8 of 100,000 patients. Sixty-six percent of lipomyelomeningocele in young patients have accompanied by hypertrophic filum terminale. It is rare to find two isolated spinal lipomas simultaneously. Embryological origin of dorsal and filar lipomas is different from each other and hence rarer to find them together. Radical resection is now being preferre...

RATIONALE Chiari type I malformation (CM1) and occult tethered cord syndrome (OTCS) are considered to be malformations associated with subtle structural abnormalities of the terminal filum. Few studies have reported patients with CM1 and OTCS. Treatment strategy for patients of CM1 associated with OTCS is controversial. PATIENT CONCERNS A 14-year-old child was admitted with intermittent pain ...
