Mastoiditis causing Sinus Thrombosis and Posterior Fossa Epidural Haematoma: Case report

Spontaneously occurring epidural haematomas are an uncommon entity. a spontaneous post fossa epidural haematoma due to sigmoid sinus thrombosis secondary to mastoiditis has not been reported in english medical literature. we report a 40 year-old man who presented to us with headache and incoordination. a magnetic resonance imaging (mri) confirmed epidural sub-acute bleeding in the right side of posterior fossa with mastoiditis and right sigmoid sinus thrombosis. a right suboccipital craniotomy and evacuation of the haematoma was done and the patient was relieved of his complains.
