Differential Diagnosis for Hypoechoic Lesion with Internal Vascularity in the Cervix
- Single Most Likely Diagnosis
- Nabothian Cyst: Although typically anechoic, a nabothian cyst can appear hypoechoic if it contains debris or blood. Internal vascularity is less common but can be seen, especially if the cyst is atypical or there's an associated inflammatory process.
- Other Likely Diagnoses
- Cervical Adenocarcinoma: This type of cancer can present as a hypoechoic lesion with internal vascularity due to its vascular nature. It's a significant consideration given the potential for malignancy.
- Cervical Stromal Invasion by Endometriosis: Endometriosis can invade the cervical stroma, appearing as a hypoechoic lesion. Internal vascularity may be present, especially if the lesion is active or large.
- Cervical Leiomyoma (Fibroid): While more commonly associated with the uterus, leiomyomas can occur in the cervix. They may appear hypoechoic and can have internal vascularity, especially if they are undergoing degeneration.
- Do Not Miss Diagnoses
- Cervical Squamous Cell Carcinoma: Although more commonly associated with a heterogeneous or hyperechoic appearance, squamous cell carcinoma can occasionally present as a hypoechoic lesion with internal vascularity. Given its potential for aggressive behavior and metastasis, it's crucial not to miss this diagnosis.
- Metastasis to the Cervix: Rarely, metastatic disease from other primary sites can involve the cervix, presenting as a hypoechoic lesion with internal vascularity. This would be particularly concerning in patients with a known history of cancer.
- Rare Diagnoses
- Cervical Lymphoma: Primary lymphoma of the cervix is exceedingly rare but can present as a hypoechoic lesion with internal vascularity due to its cellular and vascular nature.
- Cervical Sarcoma: Sarcomas are rare tumors that can occur in the cervix, appearing as hypoechoic lesions with potential internal vascularity. Their rarity makes them less likely but still important to consider in the differential diagnosis.
