Diagnosis With Brief Discussion

Diagnosis
Sclerosing Hemangioma, Papillary Type
Radiologic Findings
There is an about 2.0x1.1cm sized, well-defined, nodule in left middle lung zone. Pre-contrast CT scan shows noncalcified, homogeneous soft tissue density nodule (24HU) in lingular segment of left upper lobe. After the contrast infusion, the nodule is mildly enhanced (37HU). On lung setting, the nodule is smoothly marginated.
Brief Review
Pulmonary sclerosing hemangiomas are benign neoplasm that usually, but not invariably, are solitary. Most patients are asymptomatic. In most series females outnumber males by nearly 4 to 1. The lesion is rare in patients under 20 years of age.
Lebow and Hybbell first described sclerosing hemangioma in 1956. It is a rare benign tumor, characterized microscopically by four major histologic components: solid, papillary, sclerotic, and hamngiomatous in varying proportions. There have been many investigations of the histogenesis of the tumor, but it is still uncertain whether its origin is endothelial or epithelial. However, recent immunohistochemical and ultrastructural data support the concept that sclerosing hemangioma is an epithelial neoplasm derived from type II pneumocytes and bronchiolar epithelial cells.
Radiographically, it is a mainly solitary, well-defined, benign-looking solitary pulmonary nodule. Rarely they contain areas of calcification. The air-meniscus sign, characterized by a crescentic radiolucency at the periphery of a lung nodule, has been reported in a few cases, corresponding to enlarged alveoli with septal destruction microscopically.
Im et al reported CT findings of eight patients with sclerosing hemangioma. It appeared as well defined, juxtapleural masses in all cases. The tumors enhanced by visual criteria in seven patients. However one patient with the smallest mass (2.0x1.5cm) is poorly enhanced by visual assessment. In our case the mass is mildly enhanced after contrast infusion (13HU) because of small size and papillary subtype.
