Pulmonary sclerosing haemangioma

A pulmonary sclerosing haemangioma (PSH) is a benign neoplasm of the lung.

Epidemiology

Typically presents in middle age ( ~ 30 - 50 years of age). There is a recognised female predilection. 

Clinical presentation 

Most patients are asymptomatic. Symptoms if present will include haemoptysis, cough, chest pain, dyspnea, and pleurisy.

Pathology

It is a rare benign tumor which is microscopically characterized by four main histological components (solid, papillary, sclerotic, and haemangiomatous) in varying proportions. A thin fibrous pseudocapsule separates it from the adjacent compressed lung parenchyma.

Radiographic features

There can be significant size variability where the lesions range from under 1 cm to ~ 8 cm in diameter, although most are less than 3.5 cm.

Plain film / Chest radiograph
  • they usually tend to present as a solitary , well-defined nodular lesion (oval to rounded shadow). 
  • they occasionally contain areas of calcification
  • may show an air-meniscus sign 4 : crescentic radiolucency at the periphery of a lung nodule  
CT Chest 
  • often seen as a well defined intra-parechymal nodular mass (often juxta pleural)
  • may show a radiolucent zone around the lesion 5
  • shows significant but inhomogeneous enhancement 2,8
