Introduction
Brucellosis is a zoonotic infectious disease with various manifestations. This infection is endemic in the Middle East, especially Iran. Brucellosis can be treated readily. However, relapses and chronicity are prevalent (1). Neurobrucellosis is a focal form of brucellosis that may be life-threatening if not timely diagnosed and treated. This complication of brucellosis can present with various symptoms such as headache, meningismus, nausea and vomiting, diplopia, lethargy, and even coma. Meningoencephalitis is the most prevalent feature of neurobrucellosis. Nonetheless, cranial nerve palsies, brain abscess, cerebral venous thrombosis, subdural hemorrhage, Guillain-Barre syndrome, diabetes insipidus, myelitis, radiculoneuritis, and peripheral neuropathy are some other uncommon syndromes (2-5). Pseudotumor cerebri (PTC) has rarely been reported as the sole manifestation of brucellosis (6). Here, we have reported a case of brucellosis with severe headaches, progressive visual impairment, and fundoscopic finding of papilledema, later diagnosed as brucellosis-induced PTC.
