Tuberculosis of the pancreas: report of two cases and review of the literature

Tuberculose pancréatique : une cause rare d’ictère pseudo-néoplasique par compression de la voie biliaire principale

Isolated pancreatic tuberculosis is rare, and can mimic pancreatic carcinoma. We report a case of pseudoneoplastic pancreatic tuberculosis revealed by an obstructive jaundice in a 35-Year-old man. Surgical pancreatic histopathology showed a caseating granulomatous inflammation and diagnosis was confirmed by detection of Mycobacterium tuberculosis DNA using specific polymerase chain reaction-based assay (PCR). The patient was successfully treated with quadruple antituberculous therapy. In the context of the diagnostic work-up of a hypodense pancreatic mass, the diagnosis of tuberculosis relies on the presence of pancreatic caseating granulomas, that can be obtained by endosonography-guided biopsy, thus avoiding laparotomy.

Tuberculosis of pancreas and peripancreatic lymph nodes in immunocompetent patients: experience from China

AIM: To determine the clinical, radiographic and laboratory characteristics, diagnostic methods, and therapeutic variables in immunocompetent patients with tuberculosis (TB) of the pancreas and peripancreatic lymph nodes.

METHODS: The records of 16 patients (6 male, 10 female; mean age 37 years, range 18-56years) with tuberculosis of the pancreas and peripancreatic lymph nodes from 1983 to 2001 in the Southwest Hospital were analyzed retrospectively. In addition, 58 similar cases published in Chinese literature were reviewed and summarized. We reviewed the clinical, radiographic and laboratory findings, diagnostic methods, therapeutic approaches, and outcome in the patients. Criteria for the diagnosis of pancreatic tuberculosis were the presence of granuloma in histological sections or the presence of Mycobacterium tuberculosis DNA by polymerase chain reaction (PCR).

RESULTS: Predominant symptoms consisted of abdominal nodule and pain (75%), anorexia/weight loss (69%), malaise/weakness (64%), fever and night sweats (50%), back pain (38%) and jaundice (31%). Swelling of the head of the pancreas with heterogeneous attenuation echo was detected with ultrasound in 75% (12/16). CT scan showed pancreatic mass with heterogeneous hypodensity focus in all patients, with calcification in 56% (9/16) patients, and peripancreatic nodules in 38% (6/16) patients. Anemia and lymphocytopenia were seen in 50% (8/16) patients, and pancytopenia occurred in 13% (2/16) patients. Hypertransaminasemia, elevated alkaline phosphatase (AP) and GGT were seen in 56% (9/16) patients. The erythrocyte sedimentation rate (ESR) was elevated in 69% (11/16) cases. Granulomas were found in 75% (12/16) cases, and in 38% (6/16) cases caseous necrosis tissue was found. Laparotomy was performed in 75% (12/16) cases, and ultrasound-guided fine needle aspiration (FNA) was done in 63% (10 of 16). The most commonly used combinations of medications were isoniazid/rifampin/streptomycin (63%, n = 10) and isoniazid/rifampin pyrazinamide/streptomycin or ethambutol (38%, n = 6). The duration of treatment lasted for half or one year and treatment was successful in all cases. The characteristics of 58 cases from Chinese literature were also summarized.

CONCLUSION: Tuberculosis of the pancreas and peripancreatic lymph nodes should be considered as a diagnostic possibility in patients presenting with a pancreatic mass, and diagnosis without laparotomy is possible if only doctors are aware of its clinical features and investigate it with appropriate modalities. Pancreatic tuberculosis can be effectively cured by antituberculous drugs.

Abdominal tuberculosis with pancreatic involvement: a case report

A case of abdominal tuberculosis with pancreatic involvement is described. A 27-year-old Italian male, with no known cause of immunodeficiency and with no evidence of pulmonary tuberculosis, was admitted to our division because of acute pancreatitis. Abdominal imaging revealed a large 'tumour-like' mass in the pancreas head compressing the distal choledochous, and multiple adenopathy. Histological examination of multiple specimens removed during explorative laparotomy revealed granulomas with giant cells, caseous necrosis, and positive Ziehl-Neelsen staining. Tissue culture was positive for Mycobacterium tuberculosis. Once specific medical treatment was started, the pancreatic damage completely resolved.
