Objective: The aim of our study was to evaluate the pathological features of posterior echo attenuation of papillary thyroid microcarcinoma (PTMC) and cystic degeneration of cervical lymph node metastasis. Methods: We retrospectively evaluated the ultrasound results from 36 cases of PTMC with 20 nodules of cystic degeneration of cervical lymph node metastasis and correlated the results with the histopathologic findings. Results: The preliminary study indicated certain correlation between histopathologic findings and ultrasound results of posterior echo attenuation of papillary thyroid microcarcinoma and cystic degeneration of cervical lymph node metastasis. Conclusion: Posterior echo attenuation detected by ultrasound was associated with fibrous structures in PTMC nodules, while cystic degeneration and papillary changes of cervical lymph node metastasis in PTMC showed liquefactive necrosis, degenerative changes and enlarged follicular of nodular structures.
