Abstract

A solitary pontine lesion (SPL) is a single brainstem lesion on the trigeminal nerve pathway without any other central nervous system lesion. This research aimed to investigate the demographic and clinical features of nonpainful TNO patients with SPL and identify the most frequently affected anatomical areas using lesion mapping techniques. Demographic and clinical features were retrospectively reviewed from the patients’ charts. Brain lesions were mapped using MRIcroGL software. The study included 6 patients (three females and three males) with an SPL. The median age of the patients was 57 (range: 46–68) years. Cranial MRI displayed lesions in the dorsolateral pons and the cerebellar peduncle. The lesion mapping revealed that the lesions were on the trigeminal nerve pathway. SPL is an uncommon cause of TNO. Nonpainful SPL patients have demographic, clinical, and radiological features similar to those of painful SPL patients. The lesion mapping showed that the same brainstem areas are affected in painful and nonpainful SPL patients.
