MRI features of cellular angiomyofibroma with pathologic correlation

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Cellular angiofibroma (CAF), also known as angiomyofibroblastoma-like tumor, is a rare mesenchymal neoplasm.
• Historically, CAF has been described predominantly in the female vulva, perineum, and pelvis.
• Extratesticular mesenchymal tumors encompass a range of rare lesions within the scrotum and perineum.

Observation:

• This report details a rare case of a 60-year-old male presenting with a firm, palpable scrotal mass.
• The mass was diagnosed as a cellular angiofibroma, occurring adjacent to a scrotal lipoma.
• This represents a unique presentation of CAF in a male extratesticular location.

Findings:

• The study presents the magnetic resonance imaging (MRI) features of a cellular angiofibroma in a male patient.
• These MRI findings are correlated with the known pathological characteristics of CAF.
• The imaging demonstrates a benign cellular and fibrous tumor with significant vascularity.

Implications:

• This case expands the known anatomical distribution of cellular angiofibroma to include the male scrotum.
• The presented MRI findings are novel and contribute to the radiological understanding of this rare tumor.
• Accurate radiological characterization is crucial for the diagnosis and management of extratesticular masses.
