Pancreas contour variations can sometimes be misdiagnosed as mass lesions. This study aimed to evaluate normal pancreatic contour morphology, variations, frequency and the development of the uncinate process.
Out of 1183 consecutive computed tomography images taken in our hospital for various reasons (e.g. malignity, donor), 899 suitable images were included in the study. The following variations were identified: globular, elongated or globular-elongated contours of the pancreas head, protrusions of the body-tail surfaces and globular, lobular, globular-lobular, tapered and bifid contours of the tail. Hypoplasia and aplasia of the uncinate process were identified. All images were evaluated retrospectively by two radiologists.
Of the 899 patients, 504 (56.1%) were males. The mean age of the patients was 53.9 ± 14.7 (range 18-89). Hypoplasia of the uncinate process was found in 72 (8%) patients; aplasia was seen in 11 (1.2%) patients. Thirty-one (3.5%) of the pancreatic head variations were globular, 49 (5.4%) elongated and three (0.3%) elongated-globular. In patients with pancreatic uncinate process developmental anomaly, contour variations were also detected in the head of the pancreas. The pancreatic body-tail showed protrusions anteriorly in 76 (8%) patients and posteriorly in 11 (1.2%) patients. Seventy-two (8%) of the pancreatic tail variations were globular, 39 (4.4%) were globular-lobular, 18 (2%) were tapered and 17 (1.8%) were bifid.
Patients with pancreatic uncinate process developmental anomaly also have contour variations in the head of the pancreas. Pancreatic uncinate process developmental anomaly was seen in 9.2%. Pancreatic tail contour variation was 16.2%. The pancreatic body-tail showed protrusion in 9.2% of patients.
胰腺轮廓的变化有时可能被误诊为肿块病变。本研究旨在评估正常胰腺轮廓形态、变化、频率以及钩突的发育。
在我院因各种原因（如恶性肿瘤、供体）连续进行的 1183 次 CT 检查中，有 899 例图像适合纳入本研究。识别出以下变化：胰头的球形、伸长形或球形-伸长形轮廓，体尾部的突起，以及胰尾的球形、叶状、球形-叶状、锥形和分叉形轮廓。识别出钩突的发育不全和发育不良。两位放射科医生对所有图像进行回顾性评估。
899 例患者中，男性 504 例（56.1%），平均年龄 53.9±14.7 岁（18-89 岁）。钩突发育不全 72 例（8%），发育不良 11 例（1.2%）。胰头变异 31 例（3.5%）为球形，49 例（5.4%）为伸长形，3 例（0.3%）为伸长-球形。在胰腺钩突发育异常的患者中，也发现胰头轮廓有变异。胰体尾部向前突出 76 例（8%），向后突出 11 例（1.2%）。胰尾变异 72 例（8%）为球形，39 例（4.4%）为球形-叶状，18 例（2%）为锥形，17 例（1.8%）为分叉形。
胰腺钩突发育异常的患者胰头也有轮廓变化。胰腺钩突发育异常发生率为 9.2%。胰尾轮廓变化发生率为 16.2%。胰体尾部向前突出的发生率为 9.2%。
