The occurrence of a fatal tuberculous pancreatic abscess simulating a pancreatic tumor in an immunocompromised patient.

Introduction: Tuberculosis is currently undergoing a worrying recovery in Morocco. It is becoming a tropical disease again and can take deceptive clinical forms and involve unusual localizations. We report a rare case of pancreatic abscess due to in an immunocompromised patient.

Case Report: The patient was 48 years old and was diagnosed with HIV infection 16 months previously during a systematic check-up. He had no notable pathological history, no notion of tuberculosis contagion and no signs of tuberculosis impregnation, and was admitted for the management of epigastric pain associated with an altered general condition. Abdominal CT scan showed a bulbar perforation and multiple deep necrotic adenopathies of infectious or tumoral origin. Direct examination of the pus with Ziehl Neelsen stain was positive (1-10 BAAR/field). Molecular study using the GeneXpert MTB/RIF technique revealed complex without rifampicin resistance. The patient was put on antibacillary treatment based on isoniazid, rifampicin, ethambutol and pyrazinamide. The patient died of septic shock with multiple organ failure.

Conclusions: The diagnosis of a tuberculous pancreatic abscess may be overlooked because of its rarity and its clinical state simulating a pancreatic tumor, so it should be considered especially in endemic countries like ours.
