Summary
Extra gastrointestinal stromal tumors (GISTs) outside the GI tract are rare. This case highlights the diagnostic challenge of primary liver GIST versus metastatic GIST presenting as isolated liver lesions.
Area of Science:
- Gastroenterology
- Oncology
- Radiology
Background:
- Gastrointestinal stromal tumors (GISTs) typically originate within the gastrointestinal tract.
- Extra GISTs, originating outside the GI tract, are uncommon.
- Distinguishing primary liver GIST (PLGIST) from liver metastasis of GIST (LMGIST) can be challenging, especially with isolated liver lesions.
Observation:
- A 38-year-old male presented with multiple giant cystic-solid liver lesions.
- CT-guided fine-needle aspiration confirmed the diagnosis of liver GIST.
- The patient had a history of small intestine resection 5 years prior, complicating origin determination.
Findings:
- Over a 2-year follow-up, the largest liver lesion grew from 16 cm to 21 cm.
- No extrahepatic lesions were detected during the follow-up period.
- The case underscores the difficulty in differentiating PLGIST from LMGIST without complete patient history.
Implications:
- This review aims to improve the understanding of rare liver GIST entities.
- Enhanced diagnostic approaches are needed for accurate tumor origin determination.
- Improved diagnosis and staging of liver GISTs are crucial for patient management.

Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
