A Case of Localized Pulmonary Calcification Presenting as a Persistent Mass Lesion in an Immunosuppressed Patient Following Treatment of a Pseudomonas Pneumonia
We report a case of a persistent right upper lobe opacity following treatment for a Pseudomonas infection in an immunosuppressed patient with a recent renal transplantation. The patient underwent a surgical lung biopsy for definitive diagnosis of the mass. The lesion was composed of extensive calcif...

description | We report a case of a persistent right upper lobe opacity following treatment for a Pseudomonas infection in an immunosuppressed patient with a recent renal transplantation. The patient underwent a surgical lung biopsy for definitive diagnosis of the mass. The lesion was composed of extensive calcifications deposited throughout the lung with associated fibrosis. The patient had a history of a remote parathyroidectomy for hyperparathyroidism; however, the parathyroid hormone (PTH) and the calcium levels were still mildly elevated. No other calcified lung lesions had developed in a follow-up after the initial resection. Pulmonary calcification has been classically associated with varicella pneumonia; no viral cytopathic changes were identified for varicella or other viruses in this case. The calcification appears to be secondary to the recent Pseudomonas pneumonia. To our knowledge, this is the first report of a Pseudomonas pneumonia resulting in extensive localized pulmonary calcification. This is an important diagnostic consideration as this benign entity should be considered in patients with persistent opacities following treatment for pneumonia. |
