Intestinal tuberculosis in immunocompetent/HIV negative patients: case report of two patients

In the past, extrapulmonary tuberculosis affected approximately 70% of patients with advanced pulmonary tuberculosis. However, with the advent of highly effective therapy, intestinal tuberculosis has become rare - even more unusual in patients without immunodeficiency, HIV and pulmonary disease. The purpose of this study was to report the case of two patients diagnosed with intestinal tuberculosis and no immunodeficiency, HIV or lung disease. The first patient was diagnosed by colonoscopy performed in a mass located in the ileocecal region. After the tuberculosis treatment, the patient presented improvement regarding the mass and symptoms. The diagnosis of the second patient was achieved only with surgical resection of the lesion in proximal transverse colon. It is important for health professionals to know that intestinal tuberculosis should be considered as differential diagnosis of intestinal diseases, also for immunocompetent patients, even regarded as a rare disease.

No passado, a tuberculose extrapulmonar acometia cerca de 70% dos pacientes com tuberculose pulmonar avançada. Porém, com o surgimento da terapia de alta eficácia, a tuberculose intestinal tornou-se de ocorrência mais rara - sendo ainda mais incomum de ocorrer em pacientes sem imunodeficiência, HIV e doença pulmonar. O objetivo deste estudo foi apresentar o caso de dois pacientes diagnosticados com tuberculose intestinal, sem sinais de imunodeficiência, HIV ou doença pulmonar. A primeira paciente foi diagnosticada por meio de biópsias realizadas por colonoscopia em uma massa localizada em região ileocecal; após o tratamento da tuberculose a paciente apresentou melhora da lesão e dos sintomas. O diagnóstico do segundo paciente só foi obtido com a ressecção cirúrgica da lesão em cólon transverso proximal. É importante que os profissionais da saúde saibam que a tuberculose intestinal deve ser considerada como diagnóstico diferencial de patologias intestinais, até mesmo em pacientes imunocompetentes, mesmo sendo rara.

Pre-operative diagnosis of Meckel's diverticulum: report of a case and review of literature.

Meckel's diverticulum represents a patent omphalomesenteric duct at its junction with the ileum. Although it is a common anomaly, it is often a surgical surprise as the preoperative diagnosis is seldom established. We present an unusual case where the constellation of imaging findings was so typical that we could suggest this diagnosis prospectively and it was subsequently confirmed surgically.
