Lymphocytic interstitial pneumonitis is a benign lymphoproliferative disorder characterized by lymphocyte predominant infiltration of the lungs. It is classified as a subtype of interstitial lung disease. It also falls under the umbrella of non-lymphomatous pulmonary lymphoid disorders.

The Radiology Assistant : Lung - HRCT Basic Interpretation Lung - HRCT Basic Interpretation Robin Smithuis, Otto van Delden and Cornelia Schaefer-Prokop Radiology Department of the Rijnland Hospital, Leiderdorp and the Academical Medical Centre, Amsterdam, the Netherlands The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings. In 25 to 30% of cases the radiologic findings are atypical. In 5 to 10% of patients the chest radiograph is normal. The HRCT appearance of pulmonary sarcoidosis varies greatly and is known to mimic many other diffuse infiltrative lung diseases. Approximately 60 to 70% of patients with sarcoidosis have characteristic radiologic findings.

Wilson Professor of Radiology The use of high-resolution CT (HRCT) has proven especially effective Lymphangioleiomyomatosis (LAM) is a rare cystic lung disease that is associated with HRCT appearance alone is not sufficient to establish a definitive diagnosis of LAM, especially Radiology.

Most of our knowledge about imaging findings in interstitial lung disease comes from HRCT. On HRCT there are four patterns: reticular, nodular, high and low attenuation (table). On a Chest X-Ray it can be very difficult to determine whether there is interstitial lung disease and what kind of pattern we are dealing with.

They are usually multifocal, bilateral and peripheral, but in the early phase of the disease the GGO may present as a unifocal lesion, most commonly located in the inferior lobe of the right lung (). As with other pulmonary diseases with an interstitial component, HRCT is the modality of choice.

Knowledge of the lung anatomy is essential for understanding HRCT. The interpretation of interstitial lung diseases is based on the type of involvement of the secondary lobule. The secondary lobule is the basic anatomic unit of pulmonary structure and function. It is the smallest lung unit that is surrounded by connective tissue septa.

HRCT findings in Silicosis/CWP. Small well-defined nodules of 2 to 5mm in diameter in both lungs. Upper lobe predominance; Nodules may be calcified; Centrilobular and subpleural distribution ; Sometimes random distribution; Irregular conglomerate masses, known as progressive massive fibrosis; Masses may cavitate due to ischemic necrosis.
