Benign tumors in the lung include hamartomas and chondromas. The most common benign coin lesion is a granuloma (inflammatory nodule ), for example due to tuberculosis or a fungal infection , such as Coccidioidomycosis . [ 6 ]
When horizontal x-ray beams, commonly used in lateral projections, are used to image the breast, the fluid inside the cysts, such as milk of calcium, is imaged tangentially. [2] This technique often produces linear or curvilinear patterns of calcification. In some cases, a semilunar shape may appear, which is why this sign is called "teacup sign."
On ultrasound, a Sertoli cell tumour appears as a hypoechoic intratesticular lesion which is usually solitary. However, the large cell subtype might present as multiple and bilateral masses with large areas of calcification. An MRI may also be conducted, but this typically is not definitive. [2]
They may appear as either non-caseating or solidly caseating lesions. [20] Initially, tuberculomas appear hypodense on computed tomography (CT) scans with significant surrounding edema. [ 23 ] [ 3 ] The "target sign" is pathognomonic for tuberculoma on CT, with a nodular ring-enhancing mass and central calcification.
Benign cyst with a few thin septa, which may contain fine calcifications or a small segment of mildly thickened calcification. This includes homogenous, high-attenuation (60–70 Hounsfield units [3]) lesions less than 3 cm with sharp margins but without enhancement. Hyperdense cysts must be exophytic with at least 75 percent of its wall ...

the presence of bilateral calcification of the basal ganglia; the presence of progressive neurologic dysfunction; the absence of an alternative metabolic, infectious, toxic or traumatic cause; a family history consistent with autosomal dominant inheritance; The calcification is usually identified on CT scan but may be visible on plain films of ...
Calcinosis cutis is an uncommon condition marked by calcium buildup in the skin and subcutaneous tissues. Calcinosis cutis can range in intensity from little nodules in one area of the body to huge, crippling lesions affecting a vast portion of the body. [1]
