Abstract:
Objective To explore the CT and MRI manifestation of salivary gland mucosa-associated lymphoid tissue(MALT)lymphoma.Methods The preoperative CT and MRI images of 89 patients with salivary gland MALT lymphoma who were confirmed by surgical pathology were analyzed retrospectively.Results Salivary gland MALT lymphoma were mainly located in the parotid gland(64 cases,71.9％).The ratio of male to female was 1 ≤ 5.Sixty-nine cases(77.5％)showed concomitant Sjogren's syndrome(SS).Typical imaging findings were round or lobulated well-marginated solid masses with moderate to severe enhancement.Atypical imaging findings were all from parotid gland MALT lymphoma,including cyst-solid mixed masses(34 cases,38.2％),poorly marginated boundaries(9 cases,10.1％),and punctuate calcification(5 cases,5.6％).The average apparent diffusion coefficient(ADC)value of lesions was(0.59±0.09)× 10-3 mm2/s and the time-signal intensity curve(TIC)type was mainly type Ⅱ(66.7％).Conclusion Salivary gland MALT lymphoma exhibits certain clinical and imaging characteristics.But when occur in parotid gland,some lesions may present atypically,which require diagnosis with the aid of functional MRI.
