[Pulmonary cryptococcosis: analysis of 38 cases]

Area of Science:

• Infectious Diseases
• Pulmonology
• Radiology

Context:

• Pulmonary cryptococcosis is an opportunistic infection caused by the fungus Cryptococcus.
• This retrospective study analyzed 38 cases diagnosed between 2003 and 2010.
• The study aimed to define the clinical, radiological, and diagnostic features of pulmonary cryptococcosis.

Purpose:

• To investigate the clinical features, radiology, diagnosis, and treatment of pulmonary cryptococcosis.
• To identify characteristic radiological findings to aid in differential diagnosis.
• To evaluate the safety and efficacy of CT-guided percutaneous biopsy for diagnosis.

Summary:

• The study identified 38 community-acquired cases of pulmonary cryptococcosis, predominantly affecting males.
• Radiological findings frequently showed lesions close to the pleura, often in the lower lungs, with nodules being the most common CT presentation.
• CT-guided transthoracic needle aspiration biopsy was utilized for diagnosis, and the disease showed a high cure rate.

Impact:

• Highlights key radiological features aiding in the early diagnosis of pulmonary cryptococcosis.
• Establishes CT-guided percutaneous biopsy as a safe and effective diagnostic tool.
• Contributes to the differential diagnosis of lung lesions, improving patient outcomes.
