Diagnosis With Brief Discussion
- Diagnosis
- Sclerosing Hemangioma complicated by pneumonia
- Radiologic Findings
- Chest radiograph (Fig. 1) shows a large mass shadow with a lobulating contour in the right lower lung zone.
A cavity with an air-fluid level is visible within the mass shadow.
Contrast-enhanced CT scans through the lower thorax (Fig. 2-4) demonstrate a mass in the right middle lobe containing multiple air pockets and irregular dense calcifications.
The mass has a thin calcified rim and heterogeneous internal densities including necrotic and solid areas, and is surrounded by airspace consolidation in the periphery of right middle lobe.
There are multiple enlarged bronchopulmonary lymph nodes.
- Brief Review
- In pathologic examination, this mass was a well-encapsulated lesion with surrounding pneumonia.
This patient also had a history of empyema 4 months before the admission.
Im et al. reported that 3 of 8 patients with sclerosing hemangioma had calcification, and two had well-defined areas of low attenuation.
Cavitation is unusual finding in sclerosing hemangioma.
However, two cases have been reported in which an air-meniscus sign was identified, probably the result of disparate rates of contraction of the capsule and tumor.
The appearance of an air-fluid level in this case is more likely due to complicated infection.
