Abstract

BACKGROUND: incidentally detected adrenal lesions have become a growing clinical problem. PURPOSE: to prospectively estimate and validate the prevalence of incidentally detected adrenal lesions (adrenal incidentaloma) in patients with or without malignant disease undergoing CT. MATERIAL AND METHODS: during 18 months all adult patients with incidentally discovered adrenal lesions detected at CT were prospectively reported from the radiology departments of all hospitals in Western Sweden (1.66 million inhabitants). Frequencies of adrenal lesions initially reported at CT and at a systematic re-evaluation were compared. The interobserver variation in blindly assessing adrenal lesions was also analyzed. RESULTS: adrenal lesions were reported and verified in 339 patients (193 females; mean age 69 years, range 30-94 years). Mean lesion size was 25.8 mm (range 8-94 mm). The mean frequency of originally reported adrenal lesions was 0.9% (range 0-2.4% between hospitals). The systematic re-evaluation of 3801 randomly selected cases showed a mean frequency of 4.5% (range 1.8-7.1% between hospitals). The re-evaluation revealed 177 cases with adrenal lesions, 30% of these were submitted by the local radiologist in accordance with the study design, 23% were described in the local radiology report but not submitted to the study center, while 47% were neither locally reported nor submitted. CONCLUSION: adrenal lesions are under-reported in clinical practice. Prevalence figures for adrenal incidentalomas should therefore be interpreted with caution, especially in multi-center settings.

  • Over the last 2 decades, there has been a dramatic increase in the detection of AIs; series with contemporary high-resolution CT techniques report a prevalence close to that observed at autopsy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
