Delayed hemorrhage after microvascular decompression in a hemifacial spasm patient associated with neurosyphilis

ABSTRACT

Microvascular decompression is an effective treatment for hemifacial spasm. Hemorrhage is oneof the complications of microvascular decompression. However, delayed hemorrhage is very rare.Here, we report a case of ipsilateral cerebellar hemorrhage at day seven following microvasculardecompression. A 45-year-old woman presented with left HFS for the previous two years. Diagnostictesting demonstrated the presence of neurosyphilis. Brain magnetic resonance image was unremarkableon presentation. She received microvascular decompression and her hemifacial spasm completelyresolved after surgery. At day seven post-operatively, the patient presented with a sudden onsetheadache. Emergency computed tomography scan showed a cerebellar hemorrhage. A suboccipitalcraniotomy was performed and a cerebellar hematoma was evacuated. The delayed hemorrhage wasattributed to possible microaneurysm from syphilis.
