Fluorescence 5-ALA guidance (FG) has been widely used since the last decades of 20th century. The current work describes case series with the successful FG implementation in patients harboring posterior fossa meningiomas. In some cases, FG allowed to identify fluorescent remnants of the tumor, which were hardly seen in xenon light, and thus provided an extended tumor resection. Authors also present cases where FG revealed intimate adhesions of the tumor remnant and the arachnoid to neurovascular structures and justified the subtotal resection due to the high risk of possible morbidity and neurologic deficit.
Key words: posterior cranial fossa meningiomas, fluorescence guidance, meningiomas of the skull base, petroclival meningiomas
