A calcified granuloma in the lung is a cluster of immune cells with calcium deposits. They can be asymptomatic or cause symptoms such as wheezing and chest pain.
This means calcium is forming deposits in the granulomas. The calcium deposits make these kinds of lung granulomas more easily seen on imaging tests, such as chest X-rays or CT scans.
Calcium deposits can form all over your body, including in your soft tissues, arteries and organs. Some calcium deposits are harmless, but others can be a sign of a serious health condition. You may or may not have symptoms.
Metastatic and dystrophic calcification, defined as deposition of calcium salts in normal and abnormal tissues, respectively, can manifest in the lungs. Pulmonary ossification refers to bone tissue formation (calcification in a collagen matrix), with or without marrow elements, in the lung parenchyma. While other organs can be affected by ...
A calcified granuloma is a cluster of cells that forms as part of an immune response and hardens over time. It’s usually due to an infection and most commonly forms in the lungs, but can...
Calcification in a pulmonary nodule (PN) on imaging indicates a high probability that the lesion is benign. But not all calcified PN are benign and the differential considerations include a primary central lung carcinoid, metastasis and a primary bronchogenic carcinoma.
A high-resolution chest CT scan is a very important step in the diagnosis and evaluation of a lung granuloma. Calcium deposits in granulomas often make them visible on these scans.

Interpretation of the presence of and the specific pattern of calcification or ossification may obviate the need for invasive biopsy. In this review, specific conditions causing pulmonary calcification or ossification that may impact diagnostic and treatment decisions are highlighted.
In general, although it is tempting to believe that the source of calcium for calcification is primarily extracellular, the actual data from other tissues (bone, vascular media, and calcified cartilage) suggest an important role of intracellular calcium in initiating the calcification process.
