Ileocecal, colonic, and peritoneal tuberculosis: role of imaging in diagnosis. A case report and literature review.

Abstract

Tuberculosis is a widespread infectious disease that still remains a deadly global health problem and a condition that is life-threatening if misdiagnosed. Extrapulmonary manifestations are prevalent in the endemic areas but limited to the immunocompromised and immigrants in economically developed areas. False diagnostic situations rely on non-specific investigatory findings, the wide spectrum of clinical manifestations, and problems in discriminating between inflammation and neoplasms of the bowel. For an early diagnosis, a high index of suspicion and correlation of clinical and imaging aspects, as well as findings from colonoscopy, tissue biopsy, and microbiologic assessments, are necessary. We present a case of a patient with non-specific abdominal symptoms, mimicking a clinical syndrome of neoplastic impregnation, finally diagnosed as ileal tuberculosis with peritoneal involvement. We stress the importance of ultrasonography as a primary method of investigation, having an important role in raising the suspicion of an infectious bowel disease, as well as the role of contrast-enhanced ultrasound examination.
