Radiological characteristics of perforated pulmonary hydatid cysts

Area of Science:

• Medical Imaging
• Parasitology
• Thoracic Surgery

Background:

• Pulmonary hydatid cysts are parasitic lung infections.
• Cyst rupture into the bronchial tree or pleural cavity presents diagnostic challenges.

Purpose of the Study:

• To describe and correlate radiological signs of pulmonary hydatid cyst perforation.
• To analyze outcomes of bronchial and pleural perforations.

Main Methods:

• Retrospective analysis of 239 pulmonary hydatid cyst cases.
• Correlation of radiological findings with cyst characteristics and perforation sites.

Main Results:

• 56 out of 239 cases showed perforation into the bronchial tree.
• Radiological signs post-perforation are more specific than pre-perforation signs.
• 5 cases involved perforation into the pleural cavity, with one resulting in secondary hydatidosis.

Conclusions:

• Specific radiological signs aid in diagnosing pulmonary hydatid cyst perforation into airways.
• Pleural perforation is a risk for secondary echinococcosis development.
