Frequency of Radiological Findings and Clinical Symptoms in Patients with Pulmonary Hydatid Cyst

Abstract

• Background: The typical radiological findings of hydatic cyst are well known. But complicated hydatid cyst have unknown findings. The aim of this study was to determine radiologic findings of hydatid cyst and their relationship to signs and symptoms. • Methods: This cross sectional study was performed on 77 patients with pulmonary hydatid cyst referred to Al-zahra hospital in Isfahan. Data of age, sex, signs and symptoms and duration of them, involved lung, chest X-ray (CXR) and CT scan findings were collected and analyzed with chi square and fisher exact tests. • Finding: Seventy seven patients with mean age of 34.27 15.41 years and mean duration of symptoms of 143.36 24.4 days were evaluated. 61% were men and 75.7% were women. 51.3% of patients had opaque lesion (non complicated) in CXR and CT scan. In 37.7% of patients, the diagnosis was performed only based on CXR and clinical findings. No meaningful relationship was found between sex, clinical findings, involved lobe and side of involved lung with complicated cyst in radiology findings. • Conclusion: The diagnosis of pulmonary hydatid cyst is based on radiologic (round radiopaque lesion) and clinical findings.
