Key result
Six-month antituberculosis therapy completely resolves VT and lymphadenopathy in a patient with tuberculous lymphadenitis.
Tuberculous lymphadenitis is a rare but treatable cause of ventricular arrhythmia.
May support infectious evaluation in unexplained VT; hypothesis-generating and should not change practice.
A 56-year-old male, known to be hypertensive and with a history of cerebrovascular accident, presented with palpitations. His electrocardiogram showed ventricular premature complexes, and he was referred to a cardiologist. Holter monitoring revealed nonsustained ventricular tachycardia (VT) runs. He had one episode of VT, which was reverted by amiodarone. Clinical examination revealed multiple active lymph nodes in the neck. An excision biopsy was performed, which was suggestive of tuberculous lymphadenitis. The patient received antituberculosis therapy for 6 months, after which repeat imaging showed complete resolution of both lymphadenopathy and clinical symptoms. This case describes a rare and underrecognized cause of ventricular arrhythmia that can be successfully treated.
