    ABSTRACT: Hydatid disease, caused by the parasite Echinococcus granulosus, mostly affects the liver and the lungs with hydatid cysts which consist of three layers: (1) the outer pericyst; (2) the middle laminated membrane; and (3) the inner germinal layer. Pericyst, as the outermost layer of the hydatid cyst, is made by host cells encasing the hydatid cyst. An extremely close interaction exists between this host tissue and the parasite, and any degenerative changes of the pericyst would result in hydatid cyst degeneration or rupture. The pericyst plays an undeniably important role in the development and survival of the hydatid cyst.

    ABSTRACT: 375 in the right upper lobe (15 × 14 × 13 cm) and the second cyst in the lingula lobe (8 × 7 cm) located on the anterior and lateral border of the heart, with air fluid and water lily sign in both cysts [Figure 1]. Firstly, a giant ruptured hydatid cyst was operated by the right thoracotomy. After pericystostomy and extraction of the ruptured laminated membrane, no salvageable pulmonary parenchyma was remained in the right upper lobe. Lobectomy was performed and two chest tubes were inserted in the right pleural cavity, and then the chest was closed. The patient discharged on the fifth day postoperatively without any complications. Productive cough was decreased interestingly after surgery. After 23 days, the patient prepared for the second surgery with left anterior thoracotomy. Then, the ruptured pulmonary hydatid cyst along with thousands of small (1‑3 mm) young healthy translucent daughter cysts of the lingula lobe located over the anterolateral surface of heart excised completely with lingula resection. As a result, the pathologic examinations of ruptured laminated membranes and daughter cysts confirmed a hydatid cyst [Figure 2a and b]. On 1 year follow up patient condition is well. DISCUSSION Giant ruptured hydatid cysts were more common in the adolescents in endemic areas and was associated with
