Abstract

Pulmonary sequestration is a relatively rare malformation. Infection with common pyogenes is a frequent feature in the evolution of this disease. We report a case of intralobar sequestration infected with Mycobacterium tuberculosis in the absence of any other site of tuberculous infection. The patient underwent surgical removal of the affected lobe and subsequent antituberculous chemotherapy. At 1-year follow-up his clinical status is excellent.

Comment

Pulmonary sequestration is a congenital malformation characterized by the presence of lung tissue with abnormal or absent communication with the bronchial tree and arterial blood supply from the systemic circulation. A sequestration within the visceral pleura is classified as intralobar sequestration (approximately 75% of cases), whereas a sequestration outside the visceral pleura is classified as extralobar sequestration. Intralobar sequestration affects the lower lobes in almost all the cases

    Pulmonary sequestration is a malformation characterized by the absence of communication with the bronchial tree and presence of abnormal blood supply from a systemic artery. Despite the high frequency of various bacterial infections, infected pulmonary sequestration due to mycobacteria is rarely reported (Elia et al., 1998; Shiota et al., 2002; Sparks et al., 2008; Yatera et al., 2005). In the other 2 patients who did not fit our main clinical and histologic categories, no granulomatous inflammation could be found in their surgical specimens.

    Some of the patients with PS do not have any symptoms and the diagnosis is made by accident (15.5% of ILS patients and 10% of ELS patients).9 Severe complications of both ELS and ILS, which included fatal hemoptysis14 and massive hemothorax,15,16 cardiovascular complications,17,18 superimposed infections such as fungal infection19 and tuberculosis,20 and benign21 and malignant tumors,22 have been published. These severe complications necessitate the removal of the PS lesion if the diagnosis is certain.
