A 23-year-old female with no significant medical history developed a headache. On the evening of the following day, the headache was accompanied by nausea and vomiting. Her mother discovered her having a seizure the following morning and brought her immediately to the ED. She had another seizure and vomited upon arrival to the ED, and shortly thereafter, she was sent for a noncontrast head CT. An MRI was acquired 2 days later. Several days after these imaging studies, the patient underwent surgery.

A 27-year-old female with a past medical history of acute lymphoblastic leukemia presented with headache. She had previously received chemotherapy.

A 20-year-old female presented with left-sided headache and progressive sensorineural hearing loss. There was also a history of chronic left-sided visual impairment. Findings on the initial head CT prompted dedicated temporal bone CT and MR imaging, and then preoperative catheter angiography. Shortly afterward, the patient underwent surgical resection of a left temporal bone tumor.

The patient is a 57-year-old, right-handed, retired postal worker. He presented with a chief complaint of left-sided facial tingling. The episodes of paresthesia last only a few seconds, but have persisted for 7 years.
