Enhanced CT and CT virtual endoscopy in diagnosis of heterotopic pancreas

Table 1 Clinical and computed tomography scanning data for the six patients with heterotopic pancreas

Case	Gender	Age	Symptom	Location	Growth pattern and modality
1	M	60 yr	Carcinoid syndrome	Duodenal bulb	Exogenous, superficially lobulated, well-defined border, subserosal outer boundary was rough
2	F	59 yr	Epigastric pain (3 wk)	Gastric antrum	Circumscribed tissue, ill-defined border
3	M	68 yr	Epigastric pain (1 yr)	Gastric antrum	Circumscribed tissue, superficially lobulated, ill-defined border
4	F	3 mo	Identified during choledochal cystectomy	Mesentery	No obvious abnormality detected by computed tomography
5	M	60 yr	Abdominal distension (2 mo)	Lesser curvature aspect of gastric antrum	Superficially lobulated, well-defined border
6	M	38 yr	Cachexia	Duodenal bulb	Exogenous, well-defined border

Table 2 Detailed data from non-enhanced and enhanced computed tomography images of five of the six patients with heterotopic pancreas

		CT scanning		Enhanced CT scanning
		Lesion	Pancreas	Lesion1	Pancreas1
Case	Lesion dimensions (cm3)	CT value (Hu)	CT value (Hu)	CT value (Hu)	CT value (Hu)	Properties	Enhancement pattern
1	1.8 × 1.2 × 2.1	38.2	44.3	93.2	97.4	Solid	Homogeneous, highly enhanced
2	1.2 × 1.0 × 2.1	28.2	44.7	80	106.9	Solid	Homogeneous, slightly enhanced
3	2.0 × 1.3 × 2.0	6.9	41.5	13.5	95.5	Solid	Heterogeneous, slightly enhanced
5	1.7 × 1.9 × 2.0	–47.8	47.6	–35.8	93.4	Cystic with density of fat	Heterogeneous, slightly enhanced
6	1.9 × 1.3 × 1.0	43.3	47.1	29.1	106.6	Solid	Homogeneous, highly enhanced

Hu is the unit value for computed tomography (CT).

¹The CT values of both the lesion and the pancreas were measured during the arterial phase.
