Zusammenfassung:Loosening is a well-known complication of total hip arthroplasty. The accumulation of detritus resulting from mechanical wear forms inflammatory cells that have the function of phagocytizing this debris. Over the long term, these cells may give rise to a local granulomatous reaction. Here, we present a report on a case of pelvic pseudotumor subsequent to total hip arthroplasty, which is considered rare in the literature. The patient was a 48-year-old black man who started to be followed up medically eight months earlier because of uncharacteristic abdominal pains, dysuria and pollakiuria. He had undergone left total hip arthroplasty 17 years previously. Through clinical investigation and complementary examinations, an extra-articular granulomatous mass was diagnosed, constituting a pelvic pseudotumor. A soltura é uma complicação bem conhecida nas artroplastias totais do quadril. O acúmulo de detritos resultante do desgaste mecânico forma células inflamatórias que têm a função de fagocitar esses detritos e podem, em longo prazo, gerar uma reação granulomatosa local. A seguir, apresentamos um relato de caso de pseudotumor de pélvis pós-artroplastia total do quadril, considerado raro na literatura consultada. Trata-se de paciente de 48 anos, masculino, negro, que iniciou seguimento médico por dores abdominais incaracterísticas, disúria e polaciúria havia oito meses. Apresentava artroplastia total do quadril esquerdo havia 17 anos. Após investigação clínica e por meio de exames complementares, diagnosticou-se uma massa granulomatosa extra-articular, pseudotumor de pélvis.
