Paravertebral and diaphragmatic mass: an ectopic location of bronchogenic cyst.
Bronchogenic cysts constitute one area of the broad spectrum of developmental anomalies of the primitive foregut. They arise from anomalous budding of the primitive tracheobronchial tube and are commonly located in the mediastinum or the lung parenchyma, closely related to the tracheobronchial tree. In rare cases, they can migrate to subpleural, pericardial, paravertebral and cervical locations, if embryological connections with their parent bronchus are lost. Plain chest radiography and computed tomography have been the primary imaging modalities used for diagnosis. Computed tomography is frequently associated with misleading information with respect to the cyst density. Magnetic resonance imaging has been shown to be useful in the differential diagnosis of cystic mediastinal masses. We present a patient with two asymptomatic bronchogenic cysts found at a distance from the tracheobronchial tree.
