A 42-year-old female admitted with chief complaints of dyspnea for 3 weeks of NYHA II Class with sudden worsening of dyspnea for the last 2 days of NYHA IV Class. The patient also complained of chest pain and cough for 2 days and orthopnea for 1 day. His medical history was unremarkable. Electrocardiogram took suggestive of sinus tachycardia along with S wave in Lead I, Q wave in Lead III, and inverted T wave in Lead III. Chest X-ray done showed both Hampton's hump on the left side of chest and Westermark sign in the same X-ray film. Hampton's hump is peripheral wedge-shaped opacity abutting the pleura, signifying pulmonary infarct distal to pulmonary embolism.[1] Hampton's hump present on the right side of chest was suggestive of pulmonary infarct [Figure 1].

Chest X-ray also showed collapse of right lower lobe of the lung [Figure 2]. Westermark sign is a focal area of oligemia leading to collapse of vessel seen distal to pulmonary embolism.[2] Westermark sign was seen in the left lateral view of chest radiogram in the right upper zone and middle zone [Figure 2].

Computed tomographic (CT) angiography is suggestive of total occlusion of the right pulmonary artery and partial occlusion of the left pulmonary artery [Figure 3]. Occlusive thrombus was also present in multiple other peripheral branches of the pulmonary artery. CT scan also confirms the presence of right lower lobe collapse of the lung. The patient was treated with intravenous bolus tenecteplase followed by heparin infusion for 48 h. The patient was started on warfarin. Echocardiography before and after thrombolysis showed persistent of thrombus. The patient after initial stabilization was later referred for surgery for further management.
