The most common CT finding in hospitalized patients with MERS-CoV infection is that of bilateral predominantly subpleural and basilar airspace changes, with more extensive ground-glass opacities than consolidation. The subpleural and peribronchovascular predilection of the abnormalities is suggestive of an organizing pneumonia pattern.

Dendriform pulmonary ossification is a rare form of diffuse pulmonary ossification that is usually detected incidentally on chest radiographs or chest computed tomography (CT) imaging. In this article, we present two patients who were incidentally found to have dendriform pulmonary ossification on chest imaging. The article will present the history and imaging findings of these two cases and then review the clinical, histological, and radiographic manifestations of dendriform pulmonary ossification.

High-pitch helical CTPA acquired during BH or in FB yields comparable image quality for the diagnosis of PE and lung pathology, with low radiation exposure. Only a modest increase in lung parenchymal artifacts is encountered in FB high-pitch helical CTPA.
