Abstract
BackgroundPulmonary tumour embolism and lymphangitis carcinomatosa are complications of malignancy that may mimic the clinical presentation of pulmonary embolism.Case presentationWe present the case of a 52-year-old male patient with acute-onset right ventricular strain and dyspnoea with elevated D-dimer and without signs of pulmonary embolism on computed tomography pulmonary angiogram (CTPA) and ventilation/perfusion scintigraphy. The patient died eleven days after initial presentation. The diagnosis of pulmonary tumour embolism and lymphangitis carcinomatosa due to carcinoma of unknown origin was made post-mortem by immunohistochemical examination.ConclusionPulmonary tumour embolism and lymphangitis carcinomaosa are complications of malignancy and potential causes of acute right ventricular strain. Radiological signs are unspecific and the clinical course usually fatal. These differential diagnoses should be considered in patients with acute right ventricular strain, dyspnoea and positive D-dimer if there are no signs of pulmonary embolism on CTPA.
