Examples include apical tuberculous fibronodular changes, symmetric bilateral ground glass opacities in pneumocystis jiroveci pneumonia, cavitary filling defects of aspergillomas, hepatic and pulmonary hydatid cysts, and pleuroparenchymal changes in paragonimiasis, all of which may calcify, rarely in some cases.
These nodules can densely calcify or densely consolidate.
Since many tumors have overlapping imaging findings, knowing which tumors calcify is useful in limiting the differential diagnosis.
We present the intracranial tumors that calcify divided into intra- and extra-axial and intraventricular, in order to make the differential diagnosis more meaningful.
The suspensory ligaments and tendons of the ossicles can degenerate as a result of chronic otitis media, and they can subsequently
calcify and ossify.
