Temporal Lobe Cystic Collection and Associated Oedema: A Rare Complication of Translabyrinthine Resection of Vestibular Schwannoma

Vestibular schwannomas (VS) are benign tumours arising from the vestibulocochlear nerve. Among the management options available, surgical resection is often considered, especially if lesions are enlarging or symptomatic. Translabyrinthine (TL) resection of a vestibular schwannoma is one of three basic approaches available to the surgeon. Complications generally associated with this approach can include cerebrospinal fluid (CSF) leak, hearing and balance issues, infection, and facial nerve palsies. We present the case of a patient with a previously unreported type of complication: that of cystic CSF collection within the temporal lobe and associated oedema.
