To report our experience regarding hydatid cyst diagnosis on CT-guided biopsy and to identify the complication rate of procedure.   

we evaluated 112 CT-guided biopsies of infected thoracic lesions performed to investigate hydatid cyst masses from March 2004 to March 2009, retrospectively. All biopsies were performed by one radiologist by westcott needle number 20 and 18. The CT scans were assessed by a trained general practitioner for the size and location of lesions and pneumothorax or pneumomediastinum diagnosis and then all CT scans were double checked by the same radiologist. Lesions considered infection and their differentiations based on pathology reports.

During four year study 7 hydatid cysts (4 male and 3 female) were found with the men age 48.14 years (ranging: 25-81). The mean diameter of lesions and lesion distance to chest wall were 4.214 cm (range: 1 to 6) and 0.929 cm (range: 0 to 4), respectively. In these cases, 3 (42.9%) hydatid cyst were located in left lower, 2 (28.6%) in left upper, 1(14.3%) in right upper lobes and 1 (14.3%) in mediastinum. Pneumothorax or pneumomediastinum as complications did not present in any case.

CT–guided needle biopsy seems to be safe and feasible diagnostic modality with low risk probability of complications for hydatid cysts.
