Precontrast CT scans can reveal insulinoma, a rare tumor, by showing hyperattenuation due to psammoma bodies. This imaging technique is valuable for diagnosing insulinoma when suspected.

Area of Science:

  • Endocrinology
  • Radiology
  • Pathology

Background:

  • Insulinoma diagnosis often relies on imaging and biochemical tests.
  • Precontrast computed tomography (CT) is not typically the primary method for detecting insulinoma.

Observation:

  • A case of insulinoma presented with higher attenuation than normal pancreatic tissue on precontrast CT scans.
  • Pathological examination of the surgical specimen identified psammoma bodies as the cause of this hyperattenuation.

Findings:

  • Psammoma bodies, calcified structures, can lead to increased density (hyperattenuation) of insulinoma on precontrast CT.
  • This finding suggests a potential imaging biomarker for insulinoma.

Implications:

  • Precontrast CT should be considered in the diagnostic workup for patients with suspected insulinoma.
