目的

探讨胰腺腺泡细胞癌（PACC）的临床及超声声像图特征。

方法

收集1999年1月至2015年12月在北京协和医院就诊，经病理证实为PACC的患者13例，其中，男性9例，女性4例，年龄30~76岁，平均年龄（53.9±12.4）岁。临床症状包括腹痛、恶心、胸闷、消瘦。对13例PACC患者的临床、超声及超声造影表现进行分析。

结果

13例患者中，5例（38.5%）患者血清肿瘤标志物浓度升高。肿瘤发生于胰腺体尾部8例（61.5%），胰头部4例（30.8%），1例累及全胰（7.7%）。肿瘤最大径2.0~14.4 cm，囊实性结构4例（30.8%），边界清晰者6例（60.0%），呈外凸性生长5例（38.5%），胰胆管扩张3例（23.1%）。肝转移4例（30.8%），淋巴结转移3例（23.1%），累及血管4例（30.8%）。2例行超声造影，1例动脉期等增强，1例高增强。

结论

PACC超声表现多为边界清、外凸、体积较大、血供相对丰富的囊实性肿物，有一定特征性。

Objective

To explore the clinical and sonographic characteristics of pancreatic acinar cell carcinoma (PACC).

Methods

The clinical data and abdominal sonographic findings of 13 cases of PACC identified with pathology were reviewed, including contrast-enhanced ultrasound (CEUS) images. There were 9 males and 4 females with the average of 53.9 years old. Symptoms included upper abdominal pain, nausea, chest distress and weight loss.

Results

The serum level of tumor maker was elevated in only 5 cases. Eight masses (61.5%) were located in the pancreatic body-tail, 4 (30.8%) in the head, the whole pancreas was involved in 1 case. The mean maximal diameter was 8.0 cm. Four lesions (30.8%) presented as solid-cystic mass. Well-defined border was showed in 6 cases (60.0%). Exophytic type was observed in 5 cases (38.5%). Pancreatic ductal dilation was seen in 3 cases (23.1%), in which 2 cases showed obstruction of common biliary duct. Liver metastasis was assessed in 4 patients (30.8%), and lymph node metastasis in 3 cases (23.1%). Vessels were invaded in 4 cases (30.8%). In 2 cases by CEUS, one showed arterial iso-enhancement, the other with strong enhancement.

Conclusion

Certain characteristic clinical and ultrasonographic features could be revealed in PACC, as a sizable, exophytic, solid-cystic and relatively hypervascular mass with well-definded border.
