Summary of Clinical and US Features of Malignant Uterine Cervical Lesions
| Cervical Lesion | Clinical Features | US Features |
|---|---|---|
| Squamous cell carcinoma | 80–90% of primary cervical cancer | Heterogeneous echotexture, distortion of normal cervical morphology Increased vascularity in Doppler US (95%) Increased stiffness in elastography |
| Adenocarcinomaa | 5–20% of primary cervical cancer Preservation of endocervical epithelium due to submucosal location | Can appear as a multilocular cystic lesion |
| Adenoma malignuma | A special subtype of mucinous adenocarcinoma of the cervix Most common initial symptom is a watery discharge Often associated with Peutz-Jeghers syndrome and mucinous tumour of the ovary | Can appear as a multilocular cystic lesion |
| Other malignant tumours | Direct extension from adjacent endometrial or myometrial tumours Rare occurrence, including melanoma, lymphoma*, sarcoma, and neuroendocrine tumour Require histopathologic examination to distinguish them from cervical carcinoma | Nonspecific Heterogeneous mass with marked increased vascularity |
