Pleuropulmonary haemangiopericytoma masquerading as a post-infective encysted pleural effusion

Abstract

Haemangiopericytoma, a rare mesenchymal tumour infrequently found within the thorax, is described in a patient who presented with a pleural mass following a lower respiratory tract infection. Specific radiological features leading to a diagnosis have previously been suggested; however, these are challenged in view of the findings in this case. Haemangiopericytoma ought to be considered in the differential diagnosis of an asymptomatic enlarging pleuropulmonary soft tissue mass.
