Summary
Computed tomography (CT) effectively diagnoses pulmonary hydatid cysts by revealing cyst features and complications. Key indicators for infected cysts include air-bubbles and ring enhancement on CT scans.
Area of Science:
- Radiology
- Medical Imaging
- Parasitology
Background:
- Pulmonary hydatid cysts are parasitic infections requiring accurate diagnosis.
- Complicated hydatid cysts present diagnostic challenges.
Purpose of the Study:
- To present computed tomography (CT) findings of complicated pulmonary hydatid cysts.
- To correlate CT appearances with cyst characteristics and secondary changes.
Main Methods:
- Retrospective analysis of preoperative CT scans from 19 patients with hydatid cysts.
- Evaluation of cyst number, features, and adjacent structural changes.
- Comparison of CT findings with surgical outcomes.
Main Results:
- 12 patients had solitary cysts, 7 had multiple cysts (total 29 cysts).
- 16 of 18 complicated cysts were ruptured and infected; 14 infected cysts showed air-bubbles.
- Characteristic hydatid disease appearances were noted in 9 infected cysts; 2 showed soft tissue density.
Conclusions:
- CT is valuable for diagnosing pulmonary hydatid cysts, identifying cyst features and complications.
- Air-bubbles within the cyst and ring enhancement are strong indicators of infected hydatid cysts, regardless of other characteristic signs.
