Nonspecific Headache Diagnosed as a Brain Colloid Cyst with Hydrocephalus.

A 29-year-old male presented to our emergency department with complaints of a left frontal headache, similar to his prior headaches. He also reported about 30 minutes of facial and tongue numbness, left arm weakness, slurred speech and changes in hearing that had resolved prior to his arrival. Despite the short duration of the other neurologic symptoms, he also endorsed persistent "dizziness." Despite his history of recurrent headaches, he had never had any neuroimaging. This, as well as his reports of new neurological symptoms, prompted his care team to obtain a non-contrast brain computed tomography. The findings were consistent with a mass with mild hydrocephalus. Patient underwent neurosurgical resection of the mass at a tertiary center. He did well after surgery and was discharged on postop day 6 with a diagnosis of colloid cyst.
