Literature review highlights biopsy in neurosarcoidosis diagnosis and medical management implications.
Isolated TNS poses a diagnostic dilemma. Radiologically, it can closely mimic benign nerve sheath tumors, making frozen biopsy crucial in guiding intraoperative decision-making. When neurosarcoidosis is suspected, surgery should be limited to biopsy or partial resection to establish diagnosis and minimize morbidity, with subsequent medical management forming the mainstay of treatment.
