Abstract:
A previously healthy 33 year old lady presented with acute dysphagia with endoscopic and CT features of oesophageal carcinoma. Endoscopic ultrasound (EUS) revealed a large subcarinal lymph node compressing at the mid-oesophagus. Fine-needle aspiration (FNA) showed a single well-formed epithelioid granuloma with no evidence of malignancy. Molecular analysis showed the aspirate to be positive for Mycobacterium tuberculosis. She continues to improve with standard anti-TB medication without surgery.This is a rare case of acute dysphagia secondary to primary tuberculous mediastinal lymphadenopathy. EUS and FNA have completely altered the clinical management of this lady.
