Summary
Calcifications in bladder lesions are more frequently detected using computed tomography (CT) scans than plain films. This imaging technique reveals calcifications both on the surface and within bladder lesions, including malakoplakia.
Area of Science:
- Urology
- Radiology
- Pathology
Background:
- Plain film radiography detects calcifications in bladder lesions with a low incidence (0.5-7.0%).
- Computed tomography (CT) offers higher resolution imaging for detecting subtle calcifications.
Observation:
- CT scans of 38 consecutive bladder lesions revealed calcifications in four cases (10.5% incidence).
- Calcifications were observed on the surface and within the bladder lesions.
- One case of malakoplakia, a specific bladder condition, exhibited calcification, a previously unreported finding.
Findings:
- CT demonstrates a higher incidence of calcification in bladder lesions compared to plain films.
- Calcifications can manifest both externally and internally within bladder lesions.
- The association between malakoplakia and calcification is a novel observation.
Implications:
- CT imaging is expected to increase the detection rate of calcifications in bladder lesions.
- Radiologists and urologists should actively search for calcifications in bladder lesions when using CT.
- Further research may elucidate the significance of calcifications in various bladder pathologies.
