Summary
Magnetic resonance imaging (M.R.I.) of 200 heads revealed increased signals in the nasopharynx, suggesting Thornwaldt
Area of Science:
- Radiology and medical imaging
- Otolaryngology
- Anatomy
Background:
- The pharyngeal bursa is a midline pharyngeal structure.
- Thornwaldt's cysts are a potential finding in this region.
Purpose of the Study:
- To investigate the prevalence of increased signal intensity in the midline posterior-superior nasopharynx on M.R.I. head scans.
- To assess the potential association with the pharyngeal bursa and Thornwaldt's cysts.
Main Methods:
- Retrospective review of 200 M.R.I. head scans.
- Analysis of signal intensity in the midline posterior-superior nasopharynx.
- Correlation with anatomical location of the pharyngeal bursa.
Main Results:
- 20% of M.R.I. scans (40 out of 200) showed increased signal in the specified region.
- The location corresponded to the pharyngeal bursa.
Conclusions:
- Increased signal intensity in the midline posterior-superior nasopharynx is a common finding on M.R.I. head scans.
- Thornwaldt's cysts may be more prevalent than previously recognized.
