Visceral larval migrans (Human toxocariasis) cause of hypereosinophilia and visceral granulomas in adults]

A 24-year-old woman 2-3 months after a normal parturation presented geophagy. Due to hypermenorrhea she consulted a gynecologist and in a hemogram a 57% (6,893 x mm3) hypereosinophilia was detected. A chest TAC showed bilateral pulmonary nodules. The following tests resulted positive: ELISA IgG for toxocariasis 1:1000, isohemagglutinins anti A 1:2048 and anti B 1:512. The patient was treated with albendazole and prednisone during 10 days. One month after treatment eosinophilia decreased to 2.590 x mm3 and ELISA IgG for toxocariasis descended to 1:128. Different aspects of human toxocariasis are commented. When hypereosinophia is observed in adult patients, toxocariasis must be checked.
