A 15 year old girl presents with intermittent nausea and vomiting for 1 month; this tended to occur approximately 20 to 30 minutes following meals. Further questioning reveals the presence of continuous dull epigastric pain for 6 months. Her medical and surgical histories are unremarkable. Her full blood count is significant for a Hb of 9.8 g/dL, with MCV 73 fL, MCH 23 pg, MCHC 31 g/dL. A blood film reveals a hypochromic microcytic anemia, with anisopoikilocytosis.
Ultrasonography shows a vague mass in the stomach, with an acoustic shadow suggestive of a calcified margin.
There is a blackened, voluminous mass composed of strands of hair and food residue in the antrum and low body of the stomach, extending towards the pylorus and blocking passage of the endoscope.
There is a large, hypodense intragastric mass, which extends through the pylorus, upto the proximal jejunum. No other abnormalities are noted.
