Background:Tubercular lymphadenitis is the commonest extra pulmonary manifestation in cervical and mediastinal locations. Normal characteristics of lymph nodes (LN) have been described on ultrasonography as well as by Endoscopic Ultrasound. Many ultrasonic features have been described for evaluation of mediastinal lymph nodes. The inter and intraobserver agreement of the endosonographic features have not been uniformly established.Methods and Results:A total of 266 patients underwent endoscopic ultrasound guided fine needle aspiration and 134 cases were diagnosed as mediastinal tuberculosis. The endoscopic ultrasound location and features of these lymph nodes are described.Conclusion:Our series demonstrates the utility of endoscopic ultrasound guided fine needle aspiration as the investigation of choice for diagnosis of mediastinal tuberculosis and also describes various endoscopic ultrasound features of such nodes.
Tuberculosis is a major health problem worldwide. In India, it is highly endemic. The most common manifestation is a pulmonary disease, but involvement of the gastrointestinal tract is not uncommon with the ileocecal region being the commonest site. Gastric tuberculosis is rare and usually associated with pulmonary tuberculosis or an immunodeficient state. Here, we report a case of gastric tuberculosis presenting as gastric outlet obstruction in an immunocompetent patient without evidence of pulmonary tuberculosis. Biopsy and PCR confirmed the diagnosis, and the patient responded well to standard antitubercular treatment. Though, gastric tuberculosis is rare, it should be considered as a possibility when patients present with gastric outlet obstruction, particularly in endemic areas with tuberculosis.
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is nowadays widespread minimally invasive procedure for diagnosing a large number of benign as well as malignant lesions. We report a case of a 62-year-old immunocompetent elderly male, who presented with high-grade fever, hepatosplenomegaly and mediastinal and intra-abdominal lymph nodes. He was residing in an old haweli with bats infestation. EUS-FNA of the subcarinal and the preaortic lymph node clinched the diagnosis. A rapid on-site evaluation of the cytology material revealed organisms conforming to the morphology of Histoplasma capsulatum. The patient was immediately started on amphotericin B and itraconazole and responded well. In this case, we found the role of EUS-FNA not only in diagnosis, but also in the follow-up of the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
