RESUMEN

Peripancreatic tuberculous lymphadenopathy can mimic pancreatic cancer on imaging. There have only a few reports on varices from portal vein obstruction due to abdominal tuberculous lymphadenopathy. Iatrogenic disseminated tuberculosis is also rare. Herein, we present a rare case of peripancreatic tuberculous lymphadenopathy with ruptured duodenal varices due to portal vein obstruction. The patient presented to our hospital with hematemesis. Computed tomography revealed a peripancreatic mass. Duodenal varices rupture from portal vein obstruction due to pancreatic cancer were initially suspected. The patient underwent portal vein stenting for portal vein obstruction and endoscopic ultrasound-guided fine-needle aspiration for diagnosis, which revealed granulomas indicative of tuberculosis. The patient was discharged once because fine-needle aspiration did not lead to a definitive diagnosis of tuberculosis. Subsequently, he developed disseminated tuberculosis. Peripancreatic tuberculous lymphadenopathy can cause ectopic varices with portal vein obstruction. Tuberculosis should also be included in the differential diagnosis in the case of portal vein obstruction, to facilitate early treatment and avoid unnecessary surgery. Furthermore, fine-needle aspiration or portal vein stenting for tuberculous lesions can cause disseminated tuberculosis. Since a diagnosis might not be made until after several fine-needle aspirations have been conducted, careful follow-up is necessary after the procedure for such lesions.

RESUMEN

COVID-19 vaccines are the most critical measure for controlling the COVID-19 pandemic; however, we have little information on their complications. We experienced a case of a patient who developed hyperthyroidism complicated with atrial fibrillation and heart failure on the sixth day after the first dose of COVID-19 vaccination. This case report shows the importance of considering hyperthyroidism as a possible complication after COVID-19 vaccination.
