Beyond the ordinary headache: MRI insights into a case of Cystic trigeminal Schwannoma

Abstract

Trigeminal schwannomas are rare, benign and sluggishly growing tumours originating from the Schwann cells of trigeminal nerve. They are the second most common ⁽⁶⁾ intracranial schwannoma yet attributing to less than 0.5% of all intracranial tumours⁽⁷⁾. Often posing diagnostic challenges due to their atypical presentation. This case report underscores the crucial role of MRI in identifying these rare lesions, offering essential diagnostic clues that distinguish schwannomas from other intracranial cystic tumours. The advanced imaging capabilities of MRI are instrumental in confirming the diagnosis, supporting treatment planning, and optimizing surgical outcomes. ^(1,2)
