Primary Chest Wall Hydatid Disease: A Case Report with Multimodality Imaging Findings

Figure 5

Histopathology images using hematoxylin and eosin (H&E) stains. Low power view (H&E 20x, (a)) shows the thick fibrous capsule with a mixed inflammatory infiltrate and granulation tissue. Medium power view (H&E 40x, (b)) shows the inner side of the capsule with a laminated cyst wall lining. A higher power view (H&E 200x, (c)) shows the laminated membrane structure. In the cyst wall, some areas demonstrated acellular laminated membranous structures with cellular debris and calcifications (b, c). The adjacent lung tissue was congested and showed a chronic inflammatory reaction. There were no viable protoscolices in the cyst wall and adjacent lung.
