The left adrenal mass is difficult to differentiate from a hemorrhagic gastric diverticula: a case report.
Article in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe complex periadrenal anatomy complicates differentiation between adrenal tumors and masses of extradrenal origin. Given the nonspecific clinical and radiological presentations, misdiagnosis occurs frequently. We report a case where a gastric diverticula (GD) was initially misdiagnosed as a left adrenal tumor on imaging. CASE PRESENTATION: A 50-year-old male presented with epigastric pain and discomfort. Gastroscopy showed gastric retention. Non-contrast CT suggested a left adrenal tumor, while abdominal MRI indicated a left adrenal neoplasm, with possible adenoma or pheochromocytoma. Adrenal hormone levels were normal. Surgical exploration revealed a morphologically normal left adrenal gland. Further dissection identified a mass arising from the gastric posterior wall, densely adhered to the adrenal gland and masquerading as a left adrenal tumor. Macroscopic examination confirmed a hemorrhagic GD — accounting for the contrast enhancement seen on imaging and explaining the diagnostic challenge in distinguishing it from an adrenal neoplasm.
conclusionsTo our knowledge, this constitutes the first reported case of a hemorrhagic GD mimicking a left adrenal mass.
