Long-term disease-free survival following preoperative diagnosis and laparoscopic radical resection for Meckel’s diverticulum adenocarcinoma: A case report

Figure 1 Pre-operative technetium-99m pertechnetate Meckel scan. After intravenous administration of the radiotracer (⁹⁹mTcO₄^-), dynamic abdominal imaging was performed for 30 minutes, with one frame acquired every 5 minutes, resulting in six frames. A: Immediate gastric visualization is observed (position a in the illustration). A circular lesion with mildly increased tracer uptake is detected in the mid-abdomen (position b); B: Approximately 10 minutes post-injection, the bladder is visualized (position c), while positions a and b remain fixed with progressive accumulation of tracer; C-F: Over time, tracer uptake within the lesion is slightly increased, without notable changes in morphology or location.
