Abstract
Charis Malformation type 1 (CM1) is a common incidental radiological finding, most often asymptomatic. Congenital CM1 is often due to a small fossa posterior, while acquired CM1 may be due to a change in pressure gradient over the foramen magnum. We present a case of a previously healthy patient with a several yearlong story of occipital headache, dizziness and nausea. MRI of cerebrum showed CM1, and repeated CT-myelography showed a CSF leak in relation to the right TH7 nerve root. The leak was operatively closed. After two months, the patient had no symptoms of CM1 or intracranial hypotension.
