“…Fibrous pseudotumor may detach, allowing them to move freely, ultimately forming a "scrotal pearl" [3]. Recently, this nonneoplastic disease has been reported to be associated with IgG4-related diseases [5][6][7]. Given its rarity and potential for clinical misinterpretation as a malignant tumor, preoperative diagnosis is crucial [8].…”

Scrotal masses, whether cystic or solid lesions, are routinely evaluated using ultrasonography. Magnetic resonance imaging (MRI) may be used for further investigation in cases with atypical findings, difficult diagnoses, large masses, and/or unclear relationships with the surrounding tissues. Scrotal solid masses are divided into intra- and extra-testicular masses. A staggering 90% of the intratesticular masses are malignant, whereas 75% of extratesticular masses are benign. Extratesticular masses are less common than intratesticular masses; however, some extratesticular masses present characteristic MRI findings. Familiarity with these specific MRI features of extratesticular masses is beneficial to radiologists, as appropriate diagnoses can help avoid unnecessary invasive treatments such as orchiectomy. In this review, we describe fibrous pseudotumors, polyorchidism, adenomatoid tumors, and scrotal leiomyoma as benign paratesticular masses, focusing on their characteristic imaging features on MRI. Although these tumors are extremely rare, their MRI findings are distinctive, and accurate diagnoses can prevent unnecessary orchiectomy. In addition, to demonstrate the pitfalls of diagnosing extratesticular masses, we present a case of seminoma misidentified as extratesticular masses due to large extensions outside the testis. Spermatic cord sarcoma, including rhabdomyosarcoma, leiomyosarcoma, and liposarcoma, and metastasis to the spermatic cord are described as malignant extratesticular masses. This review focused on extratesticular masses and elaborates the imaging findings that can aid in the accurate diagnosis using MRI.

Paratesticular fibrous pseudotumors are rare benign tumors. This case reports paratesticular fibrous pseudotumors in a very young patient. A previously healthy 16-month-old boy was seen due to a growing scrotal mass. On clinical examination, there was a painless, multinodular scrotal mass. Tumor markers were normal, and a testicular ultrasound with Doppler revealed a solid, avascular, and hypoechoic mass (50x20 mm). The patient underwent excision of the scrotal mass and adjacent skin. The histological analysis revealed a paratesticular fibrous pseudotumor. Definitive treatment is surgical excision, and if there is any concern for malignancy, an extemporaneous examination should be done to confirm the diagnosis. The prognosis with fibrous pseudotumors is excellent.
