Forty-Year-Old Man With Abdominal Pain 4 Years Post-Renal Transplant: A Case Report.

Tuberculosis (TB) is an opportunistic infection 20 to 74 times more frequent in immunocompromised patients compared to the general population. The prevalence with renal transplant had a 0.5% to 15% incidence. The infection could be pulmonary or extrapulmonary (EPTB). The EPTB accounts for almost 20% of TB cases in immunocompetent people and 50% in positive human immunodeficiency virus cases. In this case report, we present a patient who attended the emergency room because of chronic diarrhea, abdominal pain, loss of weight, nocturne diaphoresis, and intermittent fever. A computed tomography scan showed retroperitoneal ganglionic conglomeration. He got into an exploratory laparotomy for histopathology specimens and paraganglionic fluid culture to a Gene Xpert MTB-RIF Assay G4, positive for rifampicin resistance tuberculosis. After an individualized treatment, trying to protect the graft's remaining function, the patient returned with acute abdominal pain and pancreatic enzymes elevation; the antibiotic management had to be suspended until the return of renal function.
