Abstract
Objective To evaluate the characteristics of parotid gland lymphoma observed by multi-slice spiral CT. Methods Clinical and CT image data of 18 patients with parotid gland lymphoma which were pathologically confirmed in our hospital were analyzed, all patients received CT scan and enhanced scan. Results Among the 18 patients, 16 were males, 2 were females; the average age was 58.7 years, and 14 patients over the age of 50. Fifteen patients with unilateral lymphoma, and 3 patients with bilateral lymphoma, all accounted to a total of 23 lesions. Among all the 23 lesions, 16 located in the following quadrant, 7 located in the following non-inferior quadrant; 17 were similarly round, 5 were round, and 1 was obviously lobulated; the average maximum diameter was 2.4 cm and the boundaries were clear finishing. The density of 16 lesions were uniform, 7 lesions were uneven with cystic necrosis, and the CT value was 16.2 ~ 43.5 Hu. Enhanced scan showed that 18 lesions were significantly enhanced early, 5 lesions were moderately enhanced, and the CT values were increased by an average of (50.3 ± 15.8)Hu; 16 lesions were homogeneous enhanced, and 7 lesions were heterogeneous enhanced; latency period showed that the density of 21 lesions were decreased rapidly, 21 lesions were slowly lowered. Conclusions Parotid gland lymphoma was mostly occurred in people over the age of 50, the lesions were mostly located under the quadrant in the parotid gland, with clear boundaries under CT scan, even or uneven slightly density, significantly enhanced under enhanced scan, and "fast-forward faster " features.关键词
