[Computerized tomographic localization of insulinomas (author's transl)].

R Zick, M Fricke, M Gebel

Medizinische Klinik

|October 5, 1979

Summary

Computerized tomography effectively locates insulinomas by analyzing tissue radiodensity. This imaging technique successfully identified four insulinomas preoperatively, outperforming other methods like angiography and sonography.

Context:

Insulinomas are rare pancreatic neuroendocrine tumors.
Accurate preoperative localization is crucial for successful surgical resection.
Traditional localization methods have limitations.

Purpose:

To evaluate the efficacy of computerized tomography (CT) in the preoperative localization of insulinomas.
To compare the detection rates of CT with angiography and sonography for insulinomas.

Summary:

Computerized tomography utilizes differences in radiodensity between insulinomas and surrounding pancreatic tissue for localization.
Four insulinomas were successfully localized preoperatively using CT, regardless of tumor encapsulation or consistency.
The smallest detected insulinoma measured 1.0 cm in diameter.

CT demonstrated superior detection rates compared to angiography (1/4) and sonography (2/4).

Impact:

CT offers a reliable and effective method for preoperative insulinoma localization.
Improved localization can lead to more precise surgical planning and better patient outcomes.
This technique enhances the diagnostic capabilities in managing patients with insulinomas.
