“…In the same study [7], the presence of pneumonia was detected during the diagnosis in 3.39% of the cases. However, in another of our studies where diagnosis dilemma in cystic hydatic cases was examined [9], it was determined that 27.27% of the cases were tracked with lobar pneumonia and following the treatments, the presence of a hydatic cyst was detected ( Figure 2).…”

A hydatid cyst, or echinococcus, is a zoonosis frequently formed by the larvas of Echinococcus granulosus. The disease appears as a slowly growing cystic mass and is asymptomatic. The disease is common in the Eastern, Southeastern, and Central Anatolia regions of Turkey. The rate of incidence of the disease in Turkey is reported as 5.7 out of 100,000 individuals. The complications of hydatic cysts appear as different clinical entities depending on the cyst's being intact or ruptured. The complications of intact cysts are usually compression symptoms, while the infection in the clinical progress of the ruptured cysts and secondary complications to the infecion are frequently seen. In this section, hydatid cyst complications in the lung, extrapulmonary thoracic findings, and respiratory system complications of hydatid cyst cases of the liver will be discussed. Complications of Intact Cysts The early period of the formation of a cyst is generally asymptomatic and they do not exhibit any symptoms until they reach nearly 5 cm in diameter [3]. The cysts without symptoms are generally detected during regular treatments [3]. The symptoms appear with pressure on the adjacent organs and the development of complications. Hydatid cysts can reach to large dimensions (≥10cm) without symptoms in the pediatric age groups since their immune response has not yet fully developed; furthermore, the parenchyma elasticity of the lung and the respiratory capacity is greater compared to adults [5]. Such cysts generally lead to chest pain and coughing, depending on bronchial and/or pleural irritation and to dyspnea, depending on the pressure on the parenchyma [5]. Larger cysts may lead to the symptoms due to pressure on the adjacent vital organs, such as the esophagus, heart, trachea, and large veins and may cause mediastinal shift, cardiac malposition and arrhythmia, pressure on the main vascular structures, and Vena Cava Superior Syndrome [6]. In our multi-centered study in which we examined hydatid cyst cases with 412 cases between 2003 and 2011, giant hydatid cyst was detected in 46 cases (11.1%) and mediastinal shift and the clinical findings depending on this were detected in 9.75% of the cases [7]. After the diognosis, the patients were scheduled for urgent surgery (Figure 1). Atelectasis caused by compression of the cyst and pneumonia as a result of atelectasis are the common complications in cases of intact cysts [6,8]. In intact cysts, pneumonia developing from atelectasis is formed as a result of the erosion of the bronchus by the cysts, cyst rupture, or more rarely, erosion occurring in the vascular structure [6,8]. The cysts in the lungs were reported to cause massive hemoptysis and subsequent mortality when they are closely adjacent to large vascular structures and the vascular wall is eroded [8]. In our multi-centered study it was detected that atelectasis depending on hydatid cyst pressure developed in 16.26% of the cases (11.6% of

“…Symptoms start to appear after the size of the cyst reaches 5 cm and create pressure in the neighboring organs or in the case of ruptured and complicated the cystic lesion [5]. Depending on the size and the localisation of the cyst, non-specific symptoms including cough, hemoptysis and chest pain occur [6]. The most frequent symptoms in the majority of the cases were non-specific ones such as cough, whilst some cases had symptoms such as fever and shivers which could occur after the cyst rupture.…”

“…Due to the fact that none of our cases had typical radiological findings for hydatid cyst and there were images mimicking abscess or tumour in direct graphics and computed tomography, the diagnostic and surgical ap-proach to the cases showed differences. Five cases that were thought to be malignant were examined in PET-CT and the SUVmax values of these examinations [2][3][4][5][6][7]8] supported the malignancy diagnosis.…”
