A cluster of atypical brucellosis in the same family

Abstract

Brucellosis is a systemic and chronic zoonotic disease passed by Brucella bacteria, which is endemic in our country. Patients presenting with different clinical manifestations are often accompanied by nonspecific symptoms like fever, night sweats, loss of appetite, weight loss and polyarthralgia. Although Brucellosis can affect all systems. Examples of musculoskeletal and hematological involvement will be discussed in the following two cases. Peripheral arthritis, sacroiliitis, spondylitis, tenosynovitis and osteomyelitis are seen in musculoskeletal involvement, while leukopenia, anemia, and rarely pancytopenia are seen in hematological involvement. Psoas abscess is a rare infection that is difficult and late to diagnose and categorized as primary and secondary. The most common cause of primary psoas abscess is Staphylococcus aureus and it usually occurs by hematogenous spread from a focus of infection in another part of the body. We aimed to present two cases from the same family, one of whom had primary psoas abscess and spondylodiscitis secondary to brucellosis; the other of whom had pancytopenia due to brucellosis.
