[Parotid adenolymphoma: the enhanced MSCT manifestations and clinical pathological analysis].

OBJECTIVE: To investigate the imaging manifestations of 16-slice enhanced CT of parotid adenolymphoma in the parotid gland and the corresponding pathology,in order to improve the understanding of the CT imaging manifestations of parotid adenolymphoma in the parotid gland. METHOD: The enhanced CT characteristics of 34 cases of parotid adenolymphoma in the parotid gland confirmed by histological pathology were retrospectively analyzed. RESULT: There were totally 86 lesions in 34 cases, of which 12 cases with lesions in bilateral sides and 22 cases with lesions in unilateral side. Sixty-six lesions located behind and below the superficial lobe of the parotid gland. The lesions showed moderate to obvious enhancement at arterial phase, and the cystic region within the lesions showed no enhancement. CONCLUSION: The relatively specific enhanced MSCT manifestations of parotid adenolymphoma in parotid gland include lesions located behind and below the superficial lobe of parotid gland unilaterally or bilaterally, sometimes exhibited as multiple masses, with clear edge, obvious enhancement and cystic degeneration inside.
