False-positive Meckel's scan in a case of infected ovarian cyst
European Journal of Nuclear Medicine
|January 1, 1985
Abstract:
Abdominal scanning using sodium pertechnetate Tc 99m is useful in demonstrating Meckel's diverticula containing ectopic gastric mucosa. However, other structures like the uterus may also concentrate 99mTc. We present a case which showed a focal area of increased uptake in the pelvis due to an infected ovarian cyst.
Insights
Sodium pertechnetate Tc 99m scans can detect Meckel's diverticula. However, this nuclear medicine technique may also show uptake in ovarian cysts, mimicking other conditions.
Area of Science:
- Nuclear medicine
- Diagnostic imaging
- Radiopharmaceuticals
Background:
- Sodium pertechnetate Tc 99m scintigraphy is a standard diagnostic tool.
- It is primarily used for detecting Meckel's diverticula containing ectopic gastric mucosa.
Observation:
- The case presented a focal area of increased radiotracer uptake in the pelvic region.
- This uptake was observed during abdominal scanning with sodium pertechnetate Tc 99m.
Findings:
- The increased pelvic uptake was ultimately attributed to an infected ovarian cyst.
- This highlights a potential false-positive finding in Tc 99m scintigraphy.
Implications:
- Clinicians should consider ovarian pathology when interpreting Tc 99m uptake in the pelvic region.
- This finding broadens the differential diagnosis for focal radiotracer concentration in abdominal imaging.
