Trigeminal Nerve Choristoma- A Rare Case Report

Choristomas are normal tissue in an abnormal location and are classified based on their predominant epithelial lining. They may contain fibrous tissue, skeletal muscle fibres, and nerve fibres. Neuromuscular choristoma (benign triton tumour) is a rare tumour that involves a large nerve trunk. Involvement of the cranial nerves by this lesion is exceptional; trigeminal nerve involvement is even rarer. This is a very rare case of intracranial trigeminal nerve neuromuscular choristoma which had an associated fatty component that also got ruptured, in a 30-year-old female who presented with a headache. The clinical presentation, radiological findings, pathological diagnosis for this case are discussed along with a review of the associated literature.
