title: An unusual cause of a pain in the neck: pseudoaneurysm from tuberculous lymphadenitis.
abstract: A pseudoaneurysm is a haematoma which is surrounded by connective tissue and communicates with the lumen of a ruptured blood vessel. It has no true defined capsule. We describe a case of tuberculous pseudoaneurysm. This is a rare complication of tuberculosis. The clinical presentation of these lesions is highly variable. Definitive diagnosis should consist of contrast-enhanced CT and arteriography. Treatment should include repair of the arterial wall by surgery, endovascular stent-graft insertion, or embolization followed by a full course of antituberculous chemotherapy. Our case is highly unusual in that the pseudoaneurysm arose from the subclavian vasculature in a patient with extrapulmonary tuberculosis only.
