title: Pathological contrast enhancement of the oculomotor and trigeminal nerves caused by intracranial hypotension syndrome.
abstract: The typical symptom of intracranial hypotension syndrome is orthostatic headache. The headache may also be accompanied by neck pain and stiffness, low backache, radicular symptoms, quadriplegia, interscapular pain, nausea/vomiting, and cranial nerve involvement symptoms (hearing and visual problems, face pain and numbness, hypogeusia). Radiologically, on cranial magnetic resonance imaging, intracranial hypotension syndrome is characterized by dural thickening and contrast enhancement, subdural effusion, engorgement of the venous structures, sagging or downward displacement of the brain, and pituitary hyperemia. Although clinical findings related to cranial nerves 3 and 5 have been described in intracranial hypotension, pathological contrast enhancement of these nerves has not. We present a 32-year-old patient whose cranial magnetic resonance imaging shows bilateral pathological contrast enhancement of cranial nerves 3 and 5 and describe a new imaging finding in intracranial hypotension syndrome.
