Introduction: Pulmonary tuberculosis (TB) is caused by the bacteria Mycobacterium tubercu-losis (MT). Rare cases of pulmonary thromboembolism along pulmonary or extra pulmonary TB were reported during the first weeks of anti-tuberculosis therapy.

 Case Report: A 28-year-old woman was admitted with complaints of ankles pain, fever, noc-turnal sweating, dyspnea and productive coughs. Patchy consolidations were seen on her chest x-ray and three sputum positive acid-fast bacillus (AFB) smears were reported in her investigations. The patient underwent anti-tuberculosis drugs and her clinical condition was improving while at the eight day of the treatment, the patient conditions suddenly deterio-rated and suffered from severe dyspnea, chest pain and haemoptysis. Moreover, sinus tachy-cardia with T waves inversion in precordial leads (V1-V3) were seen on the electrocardio-gram. Diagnosis of pulmonary thromboembolism was confirmed on computed tomography contrast angiography. In addition, echocardiography and color Doppler sonography of the lower extremities were normal. There was no evidence for hypercoagolopathy impairments in the patient. The patient was treated with warfarin and anti-tuberculosis drugs for six months, and she was completely cured and became smear negative at the end of the therapy.

Conclusion: As a result, although pulmonary thromboembolism is a rare complication of TB it should be considered in the patient with TB particularly during the first weeks of anti-TB treatment when respiratory symptoms exacerbations occur.
