Idiopathic Spontaneous Spinal Subdural Hematoma Causing Transient Paraparesis: Case Report With a Review of the Literature

Abstract

Spontaneous spinal subdural hematoma (SSDH) is even rarer, and it may occur in patients with coagulation abnormalities whose underlying diseases include neoplasm or arteriovenous malformation. Moreover, there are extremely rare cases of spontaneous SSDH without detectable structural lesion or coagulopathy. We experienced a rare case of a 27-year-old man with spontaneous acute SSDH without coagulopathy who presented with transient paraparesis. The patient received a conservative treatment and then achieved a complete recovery of the neurologic symptoms. To discuss the possible mechanism of spontaneous resolution in patients with SSDH, we report our case with a review of the literature.
