Medullary Hemorrhage that Preceded the Onset of Multiple Cavernous Angiomas

Abstract

Medullary hemorrhage is rare, and the causative role of hypertension still remains controversial. Cavernous angioma and other vascular malformations have been reported to cause medullary hemorrhage. A 53-year-old man was admitted to our hospital for vertigo. Medullary hemorrhage and multiple small hypointense lesions were detected on T2-star weighted magnetic resonance imaging (T2*W MRI). One and four months later, the appearance of new lesions confirmed the diagnosis of cerebral cavernous angioma. Cavernous angioma is often characterized by de novo appearance/progression on MRI. A follow-up MRI is required to diagnose cavernous angioma in patients with medullary hemorrhage.
