RESUMO
Brachial plexus neuropathy is a rare, but underdiagnosed condition, characterized by intense analgesic-resistant shoulder pain, followed by brachial plexus paresis and sensory symptoms. We present a case of brachial plexus neuropathy, induced by Toxoplasma gondii (T. gondii) 17 days after allogeneic hematopoietic stem cell transplantation (alloHSCT) in a patient with acute myeloid leukemia. The diagnosis was made based on the clinical presentation, magnetic resonance imaging (MRI) of the brachial plexus, and positive T. gondii polymerase chain reaction (PCR) in cerebrospinal fluid. The patient was treated with pyrimethamine, sulfadiazine, and levofolinic acid during 6 weeks, with a positive outcome.

Laminosioptes cysticola, the fowl cyst mite, was found in peripheral nerves and thoracic and abdominal viscera of an emaciated eastern wild turkey (Meleagris gallopavo) exhibiting severe torticollis, circling, loss of balance, and wing droop. Mites, sometimes accompanied by granulomatous inflammation, were abundant in brachial plexus and sciatic nerves. Mild lymphoplasmacytic perivascular cuffing was present in the cerebellum, but no direct evidence of mites or other infectious agents was found in the central nervous system. This is the first report of L. cysticola infestation in a wild turkey and of the invasion of nervous tissue by this mite.
