  Edited by ScholarGen MediAI Team Executive Clinical Summary A small superficial soft-tissue nodule may appear insignificant on an initial CT examination, particularly when it is discovered incidentally during imaging performed for an unrelated clinical complaint. Yet size alone does not determine the diagnostic importance of a soft-tissue mass. This case illustrates that principle clearly. A woman in her 40s underwent CT angiography of the chest, abdomen, and pelvis during evaluation of chest pain. The examination incidentally demonstrated a superficial soft-tissue nodule in the right buttock measuring approximately 2.1 × 1.6 cm. The lesion was not described as a typical fatty mass and was located within the superficial subcutaneous tissues. Approximately three years later, MRI demonstrated enlargement to approximately 3–4 cm. The lesion was slightly hypointense to skeletal muscle on T1-weighted imaging and markedly hyperintense on T2-weighted sequences. Thin internal low-signal ...

High-Grade Poorly Differentiated Gastric Adenocarcinoma: When a Chest Radiograph Reveals an Unexpected Gastric Cancer

Edited by ScholarGen MediAI Team Executive Clinical Summary A 90-year-old man presented with progressive bilateral leg edema for one month, accompanied by repeated episodes of malaise and dizziness associated with hypoglycemia. Physical examination revealed a nontender epigastric mass. The initial chest radiograph unexpectedly demonstrated a round, irregular opacity projected within the gastric chamber. An unusual colonic segment was also visible beneath the right hemidiaphragm. Subsequent upper gastrointestinal endoscopy revealed a large, extensively eroded exophytic mass in the subcardial region of the stomach. Histologic examination was consistent with high-grade poorly differentiated gastric adenocarcinoma . The patient was diagnosed with advanced gastric cancer and received palliative treatment. He died five months later. This case illustrates an important radiologic principle: an abnormality outside the primary field of interest may be the first imaging clue to a clinically signi...
