Cerebellar hematoma following transsphenoidal surgery

Area of Science:

• Neurosurgery
• Neurology
• Cerebrovascular Surgery

Background:

• Cerebellar hemorrhage is an infrequent complication following supratentorial neurosurgery.
• Existing literature primarily associates this complication with surgeries for aneurysms, brain tumors, or extracerebral collections.
• The precise mechanisms leading to cerebellar hematoma formation post-neurosurgery remain incompletely understood.

Observation:

• This report details a case of cerebellar hemorrhage occurring after a transsphenoidal resection of a pituitary adenoma.
• The patient underwent a transsphenoidal surgical approach, typically associated with anterior or middle cranial fossa access.
• The hemorrhage manifested in the posterior fossa, a location not commonly implicated in this surgical approach.

Findings:

• This represents the first documented case of cerebellar hemorrhage following a transsphenoidal surgical approach.
• The occurrence suggests that the transsphenoidal route, despite its trajectory, can potentially lead to posterior fossa complications.
• The underlying pathophysiology linking transsphenoidal surgery to cerebellar bleeding warrants further investigation.

Implications:

• This case expands the spectrum of potential complications associated with transsphenoidal pituitary adenoma surgery.
• It underscores the importance of considering posterior fossa complications even with anteriorly directed surgical routes.
• Further research is needed to elucidate the mechanisms and potentially develop preventative strategies for this rare complication.
