Abstract:
A ring-enhancing lesion is an uncommon cause of a dorsal midbrain syndrome. Here, we describe the case of a 60-year-old man with eye movement and pupillary findings consistent with dorsal midbrain syndrome, and in whom neuroimaging showed a single ring-enhancing lesion in the right midbrain and thalamus. Further investigation revealed a longstanding right groin mass which proved to be a malignant melanoma. His intracranial lesion was presumed to be a metastatic lesion, and treated with stereotactic radiosurgery. We report the patient's clinical course, and discuss the diagnosis and management of the solitary midbrain lesion.
