We report a case of a left fronto-temporo-parietal subdural haematoma that emerged as a complication of an endonasal endoscopic resection of a sinonasal adenocarcinoma of the left ethmoidal region.

Abstract

We report a case of a left fronto-temporo-parietal subdural haematoma that emerged as a complication of an endonasal endoscopic resection of a sinonasal adenocarcinoma of the left ethmoidal region. During the first surgical intervention, following oncological principles, the dura mater above the ethmoidal plate was removed and a skull base plasty was performed. In the post-operative phase a massive cerebrospinal fluid leak was observed and a revision duraplasty was performed the following day. Subsequently the patient was discharged on day 8 with no signs of CSF leakage. At the three month follow-up MR examination a subdural haematoma was observed and then treated by the neurosurgeon in a standard fashion. The collection was quite asymptomatic and discovered accidentally. We strongly advise the role of early post-op neuroimaging in every patient undergoing skull base procedures. We maintain that a massive CSF leak, that causes a significant reduction of intracranial pressure, should be managed as a surgical emergency, in order to reduce the risk of subdural haematoma.
