To explore the correlation between imaging features of solid-pseudopapillary tumor of pancreas (SPTP) and their pathological findings.
Analyze the imaging of 19 patients (female 15, male 4, median age 25 years) who underwent surgery for SPTP, and divide their into solid-predominance type, solid-cyst type and cyst-predominance type to compare with their pathological specimens. All patients plain and enhanced CT examination and plain and enhanced MR examination.
(1) 2 cases of solid-predominance type (11%), 13 cases solid-cyst type (68%), 4 cases of cyst-predominance type (21%). Cyst are located in the surrounding area of solid-predominance type; Solid and cyst are mixed in cyst-solid type; cyst-predominance type are thick-walled cystic tumors with nodules. (2) 12 cases (63%) show obvious signs of haemorrhage and 4 cases (21%) had calcification on CT; All cases (100%) which on MR can be seen signs of haemorrhage. (3) Pathological findings demonstrate SPTP have two ingredients: solid and cystic. However, the two ingredients occupy different ratio in different types. Haemorrhage are seen in all of tumors.
As a sort of neoplasm which preferentially arising in SPTP occur in pancreas of young women, its different types of imaging features related to their pathological findings.
探讨胰腺实性假乳头状瘤(SPTP)的影像学特征与其病理表现之间的相关性。
分析19例行SPTP手术患者(女性15例,男性4例,中位年龄25岁)的影像学表现,将其分为实性为主型、实性-囊性型和囊性为主型,并与病理标本进行对比。所有患者均行CT平扫及增强检查和MR平扫及增强检查。
(1)实性为主型2例(11%),实性-囊性型13例(68%),囊性为主型4例(21%)。实性为主型囊肿位于实性成分周边;实性-囊性型实性与囊性成分混合;囊性为主型为厚壁囊性肿物内见结节。(2)CT显示12例(63%)有明显出血征象,4例(21%)有钙化;MR检查所有病例(100%)均可见出血征象。(3)病理表现显示SPTP有实性和囊性两种成分,但两种成分在不同类型中所占比例不同。所有肿瘤均可见出血。
SPTP作为一种好发于年轻女性胰腺的肿瘤,其不同类型的影像学特征与其病理表现相关。
