胸髄腹側に限局した特発性脊髄硬膜外血腫の1治験例

Spontaneous Extradural Hematoma Localized in The Ventral Side of The Thoracic Spinal Cord:Case report

I．はじめに

　いわゆる特発性脊髄硬膜外血腫は救急治療の対象となる比較的稀な疾患で，これまでに100例をこえる報告がある^{2,9,17,20,24）}．本邦では1968年，鈴木ら^22）の報告を初めとして約20例を数える．血腫が脊髄背側に存在する例がほとんどで，脊髄腹側に限局している例は極めて少ない．

　最近われわれは胸髄腹側に発生した脊髄硬膜外血腫の1治験例を経験したので，文献的考察を加え報告する．

A case of spontaneous spinal extradural hematoma was reported. The patient, a 25-year-old housewife,was hospitalized with back pain, followed by paralysisof both legs and urinary disturbance during next2 hours. A myelogram demonstrated that contrastmedium was incompletely blocked at the level fromthe 3rd to the 4th thoracic spine by extradural mass.Unfortunately X-ray CT scan was not examined,however, a NMR-CT scan excluded disc protrusionand dissecting aneurysm of the aorta.
