ABSTRACT
We present a case admitted for evaluation of suspected idiopathic intracranial hypertension (IIH) with an unusual but important departure from the expected algorithm. A 31-year-old lady came with a two-week duration of a mild headache and one-week duration of double vision with no previously documented fever or any comorbidities. Clinically, she had papilledema and bilateral abducens palsy with no signs of meningeal irritation. MRI brain radiology was consistent with IIH. Her CSF study showed pleocytosis with elevated protein levels and normal glucose. Serology was positive for Brucella melitensis at low titers but CSF culture grew Brucella melitensis, confirming the diagnosis of neurobrucellosis. Her headache and abducens palsy improved over the first two weeks, and the papilledema resolved over two months with antibiotics. This clinical mimic is important for physicians (including neurophysicians) and Infectious Disease specialists. The radiological mimic comes from chinked (small) ventricles, unlike most meningeal diseases which can present with papilledema and abducens palsy including tuberculosis, cryptococcosis, and leptomeningeal carcinomatosis. A CSF study is mandatory in the workup of IIH despite massive improvements in imaging.
