The incidence of lung cancer metastasizing to the duodenum is rare, and its clinical presentation is still not fully understood due to its low frequency. It can be asymptomatic or present symptomatically in various ways. Here, we present the case of a 63-year-old female with an unusual case of duodenal metastasis from pulmonary adenocarcinoma, presenting with a new-onset seizure complicated by a fracture from a post-ictal fall. The diagnosis of anemia secondary to duodenal metastasis from lung cancer was delayed due to this sequence of events. The patient was ultimately found to have a circumferential mass in the third portion of the duodenum on esophagogastroduodenoscopy, which was found to be consistent with metastatic pulmonary adenocarcinoma on pathological examination.

Colorectal cancer (CRC) continues to be a significant global health issue contributing to a high mortality rate. Despite advancements in treatment, the risk of recurrence remains due to inherent mutations and the rapid turnover of intestinal mucosa. We present an exceptionally rare case of CRC metastasis to the duodenum in a 42-year-old female who has been compliant with postsurgical surveillance.

Duodenal neuroendocrine tumors are relatively rare subepithelial tumors that arise from cells of the neuroendocrine system. Small duodenal neuroendocrine tumors can be treated endoscopically because of their low potential for metastasis. This study aimed to evaluate the clinical outcomes of conventional and underwater endoscopic mucosal resection for duodenal neuroendocrine tumors.

Introduction: Mature teratomas of the duodenum are extremely rare, with only five cases reported in the English literature and none documented in Vietnam. Malignant transformation within a mature teratoma presents a challenging scenario for diagnosis and management, requiring a nuanced approach to treatment.
Presentation Of Case: We report the first documented case of malignant transformation in a duodenal mature teratoma in Vietnam.
Incidental Visualization of Gallbladder on Post-therapy [ Lu]Lu-DOTATATE Scintigraphy Mimicking a Liver Metastasis in a Duodenal Neuroendocrine Tumor.

We present a rare case of physiological uptake of [ Lu]Lu-DOTATATE in the gallbladder, observed post-therapy, in a 47-year-old man with grade I duodenal neuroendocrine tumor (NET), despite no uptake being observed pre-therapy in the somatostatin receptor-positron emission tomography. On planar scintigraphy, the gallbladder uptake could have been misidentified as liver metastasis. By utilizing single photon emission computed tomography/computed tomography imaging, we were able to precisely localize the tracer and obtain anatomical morphological characteristics, thereby averting the potential for misinterpretation of liver metastasis resulting from the gallbladder's physiological uptake of [ Lu]Lu-DOTATATE in NET patients.
