Abstract


Objective. To investigate the CT and MRI features of salivary ductal carcinoma (SDC). Method. The imaging, clinical and pathological data of 32 patients with SDC confirmed by histomathology and operation were retrospectively analyzed. The location, size, shape, boundary, relationship with surrounding tissues, density, signal, enhancement mode, calcification, cystic degeneration and metastasis were observed. Result. Of the 32 patients with SDC, 31 cases were isolated, 17 were located in the parotid gland, 8 in the submandibular gland, 2 in the sinuses, 2 in the orbit, 1 in the part of the eye, and 1 in the sublingual gland. One case had multiple lesions located in the parotid gland. The maximum diameter of tumor was 1.5-7.2cm, and the median diameter was 3.0cm. The tumor showed diffuse growth in 11 cases and focal growth in 21 cases. The boundary was clear in 24 cases and unclear in 8 cases. The lesion may invade parapharyngeal space, soft palate, facial nerve, auditory nerve, skin, surrounding muscle and bone; There were 15 cases (47%) with lymph node metastasis and 1 case with lung metastasis. MRI showed that the solid part of the tumor was dominated by isointensity and low intensity on T1 WI, mixed high intensity on T2 WI, low intensity on T1 WI and high intensity on T2 WI. CT showed uneven tumor density, with equal or low density in 15 cases, high density in 4 cases, and calcification in 7 cases. Contrast-enhanced scan showed moderate to significant enhancement of the solid part. Conclusion. SDC is mostly single, prone to cystic necrosis and calcification, with strong aggressiveness and frequent lymph node metastasis. Understanding the imaging findings of SDC is helpful to improve the accuracy of preoperative diagnosis.
