Gastric Schwannoma: A Tumor Must Be Included in Differential Diagnoses of Gastric Submucosal Tumors

Figure 2

Computed tomography (CT) image of the gastric schwannoma. (a) An oval-shaped mass (white arrow) with a size of 43 × 32 mm was observed in the lesser curvature of the stomach, which exhibited a slightly low density on plain scanning CT imaging. (b) The CT value of the mass was about 38 HU before the injection of contrast medium. The mass showed delayed enhancement with a CT value of 53 HU on arterial-phase enhanced CT scanning. (c) The CT value of the mass was slightly increased (68 HU) on portal venous-phase enhanced CT imaging. (d) The CT value of the mass was increased (78 HU) on delayed enhanced CT scanning after a delay of 3 minutes.
