Objective:

To analyze the manifestations of pancreatic adenosquamous carcinoma on dynamic contrast-enhanced CT.

Methods:

Nine patients (6 men and 3 women; mean age

58.7 years; range

44-73 years) with pancreatic adenosquamous carcinoma confirmed by pathological examination underwent CT examination. The location

size

margin

contrast enhancement were evaluated.

Results:

The masses were localized in the pancreas (head in 3 cases

body and tail in 6 cases). The tumor size ranged from 2.0 cm2.0 cm to 10.0 cm6.6 cm

with an average size of 3.7 cm4.8 cm. All masses were ill-defined. Five masses i

nvaded the peripancreatic tissues. The solid components CT values were (30.74.7) Hu

(60.214.5) Hu and (71.221.4) Hu on plan scan

arterial phase and portal vein phase. Eight masses with the presence of central necrosis showed heterogeneous and poorly enhanced areas. Only one tumor was moderately enhanced. Two patients with lesions in the head of pancreas had liver and lung metastases.

Conclusion:

CT imaging can provide useful information in the diagnosis of pancreatic adenosquamous carcinoma.
