RESUMO
@#Toxoplasmosis is a worldwide zoonosis caused by an intracellular protozoan parasite, Toxoplasma gondii. We report here a diabetic patient who was diagnosed as toxoplasmosis with multiple cranial nerve palsies and cavernous sinusitis. A 37-year-old male presented with an 11-day history of gingival pain, one day history of ptosis and diplopia. He has been having diabetes mellitus for 6 years, and has a history of contact with cats. After admission, his symptoms worsened with right 3rd to 7th cranial nerve palsies. The brain magnetic resonance imaging (MRI) showed cavernous sinusitis in the right sellar region. Serology for toxoplasma was positive for IgM and negative IgG. The patient was treated with oral clindamycin (900 mg/day) and dexamethasone (15 mg/day). The right visual acuity and lid-conjunctival swelling improved after 3 days. At follow-up after a month, the movement of the right eye significantly improved. This case demonstrate the rare occurrence of multiple cranial nerve (3rd to 7th) palsies from toxoplasmosis cavernous sinusitis, which is a potentially treatable condition.
