Unusual complication of cervical tuberculous lymphadenopathy.

Lymphadenopathy is the most common form of extrapulmonary tuberculosis; cervical region being the most frequent site. Yet, tuberculous cervical lymphadenopathy is rarely associated with Internal Jugular Vein (IJV) thrombosis. We report right IJV thrombosis with isolated cervical tuberculous lymphadenopathy in a 22-year-old woman. Anti-tuberculous treatment resulted in complete regression of lymphadenopathy but anticoagulation treatment failed to restore the caliber of thrombosed IJV to normal. Thrombosis of adjacent IJV is a potential complication of delay in diagnosis and treatment of cervical lymphnode tuberculosis.
