Pseudotumor cerebri associated with neuroborreliosis and intracranial sinus hypoplasia

Neuroborreliosis, an inflammation of the central nervous system caused by Borrelia burgdorferi sensu lato, is a relatively uncommon presentation of Lyme disease, occurring in approximately 3% of infected patients. Pseudotumor cerebri, defined as increased intracranial pressure without an intracranial mass or obstruction of cerebrospinal fluid (CSF) flow, is a rare symptom of neuroborreliosis. Increased intracranial pressure is occasionally associated with aplasia or hypoplasia of central venous collectors in otherwise healthy individuals. We present a 9- year-old female patient with pseudotumor cerebri secondary to acute neuroborreliosis with a concomitant unilateral hypoplasia of sigmoid and transverse sinuses. She presented with acute onset of headache, intermittent diplopia with right abducent nerve palsy and erythema migrans on left forearm and right popliteal fossa. Clinical presentation and laboratory tests showed papilledema, diffuse slow activity on EEG, increased CSF pressure (opening pressure 600 mmH2O, stabilized at 400 mmH2O), CSF pleocytosis (18/3 lymphocytes) and positive serum and CSF anti-Borrelia burgdorferi antibodies. She was started on ceftriaxone (2 g/day) for a total of 30 days. Diplopia receded after the lumbar puncture, headache and erythema migrans receded on antibiotic therapy. Infection of the central nervous system with Borrelia burgdorferi might be a trigger for development of pseudotumor cerebri in patients with intracranial sinus hypoplasia, leading to a rare manifestation of neuroborreliosis.
