What is a hyperdense nodule?

Small hyperdense nodules are nodular opacities measuring less than 10 mm in diameter, showing focal or diffuse distribution in the lung parenchyma. Small hyperdense nodules can be secondary to dystrophic calcification in previously damaged lung parenchyma.

Is a growing lung nodule always cancer?

Yes, lung nodules can be cancerous, though most lung nodules are noncancerous (benign). Lung nodules — small masses of tissue in the lung — are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan.

What makes a pulmonary nodule a hyperdense nodule?

Hyperdense pulmonary nodules are a subset of pulmonary nodules that have relatively increased attenuation, usually caused by calcification within the nodule. Here, we broadly refer to a nodule as a pulmonary opacity <30 mm. Differential diagnosis.

How to determine if you have a lung nodule?

Pulmonary Nodules and Lung Lesions 1 Causes of Lung Nodules. Lung nodules can be either benign (noncancerous) or malignant (cancer). 2 Diagnosis. If we suspect that you have a pulmonary nodule, we will conduct a physical examination and order tests to confirm the diagnosis. 3 Minimally Invasive Surgery. 4 Clinical Trials.

What is the opacity of a pulmonary nodule?

Here, we broadly refer to a nodule as a pulmonary opacity <30 mm. calcified pulmonary nodules are a specific group of hyperdense nodules and finding calcification in a nodule significantly narrows the differential.

What causes a calcified nodule in the lungs?

calcified pulmonary nodules are a specific group of hyperdense nodules and finding calcification in a nodule significantly narrows the differential. non-calcified hyperdense pulmonary nodules are predominantly the result of inhalational exposure to substances, although embolization of material may cause dense nodular opacification within the lung.
