“…75,76 This VQ scan pattern can also be seen in idiopathic PH, septic emboli, fat emboli, and talc granulomatosis in IV drug abusers. 75 This is different from the larger mismatched perfusion defects seen in the larger pulmonary arteries in CTEPH although features overlap and diagnosis is not conclusive. 77 In PTTM, there are no specific diagnostic signs on a Chest CT but there may be ancillary findings related to the tumor that may prove helpful in pinpointing the diagnosis.…”

“…The VQ scans of these patients typically show multiple symmetric peripheral subsegmental mismatched perfusion defects that are distributed evenly throughout the lungs 75 , 76 .

This is different from the larger mismatched perfusion defects seen in the larger pulmonary arteries in CTEPH although features overlap and diagnosis is not conclusive 77 .…”

Chronic thromboembolic pulmonary hypertension (CTEPH) is caused by mechanical obstruction of large pulmonary arteries secondary to one or more episodes of pulmonary embolism. Ventilation perfusion scan is the recommended initial screening test for this condition and typically shows multiple large mismatched perfusion defects. However, not all patients with an abnormal ventilation perfusion scan have CTEPH since there are other conditions that be associated with a positive ventilation perfusion scan. These conditions include in situ thrombosis, pulmonary artery sarcoma, fibrosing mediastinitis, pulmonary vasculitis and sarcoidosis, among others. Although these conditions cannot be distinguished from CTEPH using a ventilation perfusion scan, they have certain characteristic radiological features that can be demonstrated on other imaging techniques such as computed tomography scan and can help in differentiation of these conditions. In this review, we have summarized some key clinical and radiological features that can help differentiate CTEPH from the CTEPH mimics.

A 47-year-old woman was admitted to the hospital because of dyspnea for the past three months. She was previously diagnosed with pulmonary embolism. She had been operated on for a colon tumor five years ago and no residual cancer was detected on oncological follow-up. Her transthoracic echocardiographic and transesophageal echocardiographic evaluation showed a hypertrophic right ventricle occupied by a 2.7 x 4.8 cm immobile mass obliterated to the right ventricle cavity. All the non-invasive tests were consistent with thrombus prediagnosis. She underwent surgery. Mass was resected from the right ventricle as much as possible. Histopathology of surgical material revealed metastatic spindle cell adenocarcinoma.We aim to increase the awareness of the differential diagnosis of thrombus or tumor, thereby leading to appropriate management.

“…The incidence of pulmonary tumor embolism varies widely among several studies, ranging from 3% to 26% [ 2 ]. Symptoms of microscopic pulmonary tumor emboli include clinically unexplained subacute, progressive dyspnea, hypoxia, chest pain, cough, and respiratory alkalosis [ 2 , 5 , 6 ]. Right-sided heart failure and pulmonary hypertension are occasionally noted [ 2 ].…”

A Case Report of Breast Cancer with Extensive Pulmonary Lymphovascular Tumor Emboli

et al. 2012

We describe a patient with breast cancer who relapsed with an extensive pulmonary lymphovascular tumor embolism. A 38-year-old female, who previously received neoadjuvant chemotherapy and curative resection of breast cancer, underwent adjuvant chemotherapy and was referred to the emergency room because of sudden-onset pleuritic chest pain lasting for 10 days. Despite a trial of empirical antibiotics, the chest pain and the extent of consolidative lung lesion on chest radiographs rapidly aggravated. We performed an open lung biopsy to confirm the etiology. The histopathological review revealed a hemorrhagic infarction caused by lymphovascular tumor emboli from a metastatic breast carcinoma. Palliative first-line chemotherapy was administered, consisting of ixabepilone and capecitabine, and the lung lesion improved markedly.
