Summary
A rare case highlights that the "sleigh-bell" sign in lung cavities is not exclusive to aspergilloma. This finding is crucial for diagnosing fungal ball infections in diverse geographical regions like Africa.
Area of Science:
- Pulmonology
- Infectious Diseases
- Radiology
Background:
- Tuberculous sequestration can predispose to secondary fungal ball formation in lung cavities.
- Aspergilloma diagnosis often relies on characteristic imaging findings.
Observation:
- An 18-year-old male presented with a large right upper lobe cavity.
- Initially, the cavity contained a tuberculous sequestration.
- Two years later, the cavity was occupied by a fungus ball.
Findings:
- The "sleigh-bell" sign, typically associated with aspergilloma, was observed.
- This case demonstrates the sign is not pathognomic for aspergilloma.
- Fungal ball infections are more prevalent in Africa than previously thought.
Implications:
- Radiological findings must be interpreted cautiously in the context of clinical presentation.
- Increased awareness of fungal ball prevalence in Africa is warranted for timely diagnosis and treatment.
- This case broadens the differential diagnosis for lung cavity imaging findings.
