A rare cause of lower abdominal and pelvic mass, primary tuberculous psoas abscess: a case report.
BACKGROUND
Tuberculous psoas abscess was usually associated to complicate Pott's disease, but it can also be secondary to direct extension from other adjacent structures or haematogenous spread from an occult source. However, the occurrence of this entity as the presenting manifestation of tuberculosis, without evidence of active infection elsewhere, has been seldom reported.


METHODS
We report a clinical case of a 64-year-old immunocompetent female that presented with left lower abdominal pain and a soft tissue mass over the left iliac fossa and inguinal regions due to a primary tuberculous psoas abscess. Early diagnosis and prompt treatment with percutaneous drainage guided by ultrasound along with antituberculous drugs, lead to a satisfactory outcome.


CONCLUSIONS
The purpose of this case report is to point out attention to the diagnostic challenge of tuberculous psoas abscess in the absence of tuberculosis in other organs or a predisposing condition. A brief review of the literature about its epidemiology, etiology, clinical features and management is discussed over the text.
