A 24-year-old male presented with complaints of cough and fever that started two weeks ago. Axial thorax computed tomography scan revealed a cavitary lesion “showing a grape cluster appearance” in the right lower lobe (Fig. 1A). There was no growth in sputum culture. Presurgical anthelmintic treatment has been not used. The patient underwent right thoracotomy three weeks after his complaints began. Daughter vesicles were seen at the apex of the cavity when the cavitary lesion was opened (Fig. 1B). Capitonnage was performed for the cavity. Histopathologic examination identified the lesion as a hydatid cyst.
A ruptured pulmonary hydatid cyst can be confused with many other benign or malign diseases. Radiologically, there are many radiological signs associated with the hydatid cyst.1,2 In rare cases such as ours, daughter vesicles can be seen in the ruptured cavity with a grape cluster appearance.
