A 72-year-old woman who presented with a unilateral oculomotor nerve palsy was shown to have a very rare condition: multiple dural arteriovenous fistulae (DAVF) involving the cavernous and sphenoparietal sinuses. The sphenoparietal DAVF was cured completely by transarterial embolisation. Symptomatic relief was accomplished by this procedure. The cavernous sinus DAVF progressed to acquire cortical venous drainage, and was obliterated completely by transvenous embolisation.
Spontaneous extradural hematomas are rare and may be caused by pericranial infections, bleeding tendencies, or vascular abnormalities of the dura mater. The authors describe a case of spontaneous bilateral extradural hematomas assumed to be caused by a bleeding tendency with hypofibrinogenemia. A brief review of the literature is reported.
A 72-year-old female with intradiploic haemangioma associated with epidural haematoma is reported. MRI finding of the lesion is described. The cause of the epidural haematoma is speculated due to fragile vessels attached directly to dura mater through the pores of the inner table of the diploë.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
