Excision of large solid haemangioblastomas of the cerebellopontine angle by a skull base approach.
Solid haemangioblastomas can be difficult to treat surgically because of their hypervascularity and requirement for circumferential dissection. We report two cases of large solid cerebellopontine angle haemangioblastomas that were safely resected utilizing wide transtemporal posterolateral skull-base exposures. In both cases, good tumour exposure was achieved with trans-cochlear approaches and division of the sigmoid sinus. These were large tumours and we felt that the added complexity of the approach was justified by providing panoramic exposure to allow safe resection.
