AbstractBackground: Isolated pancreatic tuberculosis is very rare and closely mimics pancreatic cancer. Extra pancreatic involvement is very rare and has been rarely reported. Aim: Study the involvement of mediastinal/intra-abdominal lymph nodes, spleen, liver, and left adrenal in patients of isolated pancreatic tuberculosis using endoscopic ultrasound (EUS). Patients and Methods: Retrospective analysis of the records of 16 patients (12 males; mean age 37.8 ± 9.3 years) with pancreatic tuberculosis seen over last 4 years was done. Results: All 16 patients had a well-defined predominantly hypoechoic mass lesion in the pancreatic head and 7/16 (43%) patient had isolated pancreatic tuberculosis with no lymphadenopathy or extrapancreatic involvement. Nine (57%) patients had involvement of the peripancreatic lymph nodes and 6 (38%), 3 (19%), and 2 (13%) patients had celiac, periportal, and mediastinal nodes involvement, respectively. The diameter of the lymph nodes ranged from 1.2 cm to 2.6 cm with celiac lymph nodes being the largest. The left adrenal had normal morphology on EUS in all patients. The spleen and left lobe of the liver were also normal on EUS. Conclusions: Extra pancreatic involvement is seen in up to one-third of patients with presumed isolated pancreatic tuberculosis with involvement of peri-pancreatic and celiac lymph nodes being the commonest.
