Case in brief
A 33-year-old woman presented with a painless, pedunculated right vulvar mass, excised and diagnosed pathologically as angiomyofibroblastoma (AMFB). Follow-up pelvic CT showed a small irregular enhancing lesion at the site, and MRI later demonstrated a 6.1 × 4.8 × 2.8 cm heterogeneous tumor with T2 hyperintensity, marked post-contrast enhancement, and mild diffusion restriction. Excision confirmed recurrent AMFB. She remained free of recurrence for four years after the second operation.
What made this case unusual
The case documents recurrent vulvar AMFB with MRI features including heterogeneous signal, strong enhancement, and mild diffusion restriction.
Diagnostic / clinical pearl
A new enhancing vulvar lesion after AMFB excision may represent recurrence; MRI can characterize the lesion, with pathology confirming the diagnosis.
Why it matters
The report highlights MRI monitoring as an option for patients with recurrent AMFB who are concerned about repeated surgery.
