title: Endobronchial echinococcosis presenting as non-resolving pneumonia.
abstract: Hydatid disease of the lungs is caused by larval cysts of the Echinococcus tapeworm. Pulmonary cysts may occasionally invade bronchi or pleura as a result of coughing, trauma, or elevated intra-abdominal pressure. We present the case of a patient evaluated for non-resolving pneumonia whose radiographic and bronchoscopic findings were strikingly similar to those seen in pulmonary tuberculosis with endobronchial invasion; he was ultimately diagnosed with pulmonary echinococcosis. This case underscores the importance of considering unusual diagnoses even when typical features of more common conditions are present.
