Delayed Traumatic Intracranial Lesion

A retrospective analysis of 33 cases with operated delayed intracranial lesion who were admitted to EU1 Ji General Hospital from January 1990 to December 1992 was made according to their age and sex, etiology, lesion site, time interval to finding delayed intracrainal lesion, brain CT findings, relationship of GCS in initial and delayed lesion, associated injuries, treatment and prognosis(GOS). The results were follows : 1) The young males on first to second decade were most frequently affected. 2) The most common caused was pedestrian accident by motor vehicle, followed by fall down. 3) The most common associated injury was skull fracture, followed by skeletal injury of extremity. 4) The most common delayed intracranial lesion was delayed epidural hematoma on youth. 5) The most frequent time interval when the delayed intracranial lesion may be occurred was from 12 hr to 24 hr after admission. 6) The most possible intial lesion which the delayed epidural hematoma may be occurred was scanty hematoma with pnumocephalus or CSF leakage. 7) The GOS(Glasgow Outcome Scale) of analysed 33cases were good in 60% and poor in 40%, i.e good recovery(42%), moderate disability(18%), severe disability(15 %), vegetative state(12%), death(12%).

Peripheral Neuroepithelioma Arising from the Cauda Equina: Case Report

An unusual case of intraspinal peripheral neuroepithelioma arising from the cauda equina is reported. The patient, a 21-year old female, suffered from low back pain with radiation to the posterior aspect of both legs. Myelographic, computed tomographic scan and magnetic resonance imaging studies of lumbosacral spine showed the intradural extramedullary mass lesion on the L3-S1 level which was excised surgically, but recurred rapidly. It could be diagnosed by the histopathologic findings. The postoperative radiotherapy and chemotherapy were administered. We report this rare case with review of the literatures.
