Further evaluation can certainly be done with an MRI or CT scan (with the MRI being more accurate (sensitivity 90 percent, specificity 90-99 percent).
A more definitive evaluation can be considered by biopsying the lesion. However, this is a debatable approach since hemorrhage can happen when biopsying a hemangiomia.
Repeating an MRI serially to ensure the lesion isn't growing is a reasonable approach.
Regarding the lymph nodes - various types of genitourinary infections can lead to enlargement. If they continue to enlarge or persist, a biopsy can be considered to ensure they are not malignant.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.

• Regarding differentiation between a benign and a malignant mass (cysts), an experienced radiologist’s opinion would be very helpful, but for knowing the exact/ true nature of the cyst/ hemangioma a biopsy is necessary.
• Serum alpha 1 fetoprotein levels can be of help.
• The change in size of the cyst in 1 year can occur & could be due to multifactor reasons.
• Are the inguinal lymph nodes still enlarged after 1 year, could have been enlarged from an infective cause, why do you feel that you need imaging of the lymphatic system?
