Alleged Misinterpretation of PET-CT in Esophageal Carcinoma Staging: A Medico-Legal Case Report.
Article in Cureus, 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
Diagnostic imaging is pivotal in the staging of esophageal carcinoma, yet interpretation of metabolic findings can be challenging because positron emission tomography/computed tomography (PET/CT) is highly sensitive but may lack specificity, sometimes limiting differentiation between primary and metastatic lesions without histopathological correlation. We report a medico-legal case involving an alleged misdiagnosis in which a metastatic lymph node was perceived as a synchronous pancreatic malignancy, purportedly delaying treatment. A 65-year-old female presented with upper abdominal discomfort and was diagnosed with esophageal squamous cell carcinoma via endoscopy. Subsequent staging with 18F-FDG PET/CT revealed a hypermetabolic lesion in the pancreatic body, characterized as neoplastic, with a recommendation for clinical correlation. The patient interpreted this finding as a second primary cancer (pancreatic), resulting in significant distress. An endoscopic ultrasound-guided biopsy subsequently confirmed that the lesion represented a metastatic lymph node of esophageal origin. The patient underwent palliative chemotherapy but died from disease progression 14 months after diagnosis. A legal claim alleged that the diagnostic investigation of the presumed "pancreatic mass" delayed life-saving treatment. This case highlights the limitations of PET/CT specificity and the critical role of tissue diagnosis in oncologic staging; medico-legal analysis indicated that the imaging report met the standard of care by identifying the abnormality and recommending biopsy. Expert review concluded that the timeline of care was appropriate for complex staging and that the outcome was driven by the aggressive biology of stage IV esophageal cancer rather than diagnostic delay, underscoring the need to manage patient expectations regarding imaging uncertainty and reaffirming that adherence to diagnostic algorithms, including confirmatory biopsy, constitutes the standard of care even when it may be perceived as causing delays.
