Aneurysms arising from the posterior inferior cerebellar artery (PICA) are
uncommon, accounting for 0.5e3% of all intracranial aneurysms. Symptoms and signs usually
include subarachnoid hemorrhage, neck pain, dizziness, and coma. We describe a patient
who presented with cervical myeloradiculopathy (manifested by neck, shoulder, and arm pain)
and an unsteady gait whose symptoms persisted after surgery on the cervical spine. A PICA
aneurysm was diagnosed incidentally when we performed computed tomography (CT) of the
brain and angiography after he fell into a coma. The patient was successfully treated with endovascular
therapy. We emphasize that the symptoms of a PICA aneurysm may clinically mimic
cervical myeloradiculopathy, and that PICA aneurysms may thus be overlooked. |
