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.
- 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 embolisation of material may cause dense nodular opacification within the lung.
