A case of cerebral vasculitis due to neurobartonellosis

We report a case of a 60-year-old right-handed woman with hypertension, hyperlipidemia, and hypothyroidism who presented with a three-week history of recurrent thunderclap headaches accompanied by photophobia, phonophobia, nausea, and vomiting. She reported one brief episode of slurred speech, expressive aphasia, right facial droop, and right hemiparesis suggestive of a TIA. Family history was remarkable for primary angiitis of the CNS (PACNS) in the mother. Neurologic examination was unremarkable. CT of the head was negative; CT angiography (CTA) of the head and neck suggested fibromuscular dysplasia in bilateral cervical internal carotid arteries and distal right vertebral artery. MRI of the brain showed no correlating abnormalities. A digital subtraction angiography (DSA) revealed multivessel intracranial medium and large vessel narrowing and fusiform dilatations, suggestive of reversible cerebral vasoconstriction syndrome (RCVS) vs vasculitis. Subsequent MR intracranial vessel wall imaging (IVWI) showed multifocal concentric vessel wall thickening and enhancement consistent with vasculitis (figure). Transcranial Doppler showed no evidence of elevated intracranial velocities. CSF studies were unremarkable with an opening pressure of 10 cm H2O, 2 white blood cells (normal 0–5/mm3), 2 red blood cells (normal 0–1/mm3), 58 mg/dL glucose (normal 40–70, serum glucose 87), 41 mg/dL protein (normal 15–45), normal Q-albumin ratio, normal IgG synthetic rate, ...
