paracoccidioidomycosis (PCM) is a polymorphic systemic granulomatous inflammatory disease determined by Paracoccidioides brasiliensis, one of the 10 leading causes of morbidity and mortality among the parasitic diseases endemic in Brazil. Objective: To identify the following aspects of PCM by ultrasound (US) and computed tomography (CT): abdominal changes, intensity and characteristics of the observed images, frequency of changes depending on clinical presentation, differences from other nosological entities. Patients and methods: This was a retrospective, observational, cross-sectional study carried out with 35 patients with PCM treated at the Hospital das Clinicas (HC) at the Universidade Federal de Minas Gerais (UFMG). Patients with tuberculosis, bronchial asthma, generalized chronic obstructive pulmonary disease, or in contact with silica or mines, as well as those with granulomatous diseases at any point in their current or past clinical history and detected through serology, anatomopathology or microbiological exams were excluded. Collected data were transcribed into SPSS for Windows® for statistical analysis. The studywas approved by the UFMG Ethics Committee (082/00). Results and conclusion: CT and U.S. showed involvement of abdominal organs in all forms of PCM, including lymphadenopathy (40%), hepatomegaly (37%), splenomegaly (37%) and adrenal involvement (17%). Gallbladder and retroperitoneal musculature involvement were also observed, along with ascites and pleural effusion. Lymph node calcification, adrenal involvement and ascites constituted evidence of high probability of PCM even though these findings are not enough to differentiate PCM from tuberculosis. Chronic and sequelae forms, abdominal involvement is more frequent than indicated by the clinical manifestations.
