Abstract PDF: PURPOSE: To evaluate the specific radiologic findings of testicular lymphoma which will be able to differentiated from other testicular tumors. MATERIAL AND METHODS: Pathologically confirmed eight cases were included in this study. All eight cases were performed ultrasonography and four cases were performed magnetic resonance image. On ultrasonography, the size, location, shape, margin, internal echogenicity, homogeneity and vascularity were evaluated. On magnetic resonance image, the shape, margin, homogeneity, signal intensity on T1- and T2-weighted images, degree and homogeneity of the contrast enhancement and contrast enhancement change on dynamic enhancement study. RESULTS: The margin of the mass was smooth on 6 of 8 patients. Internal echogenicity of the mass lesion was hypoechoic than normal testicular parenchyme on 7 of 8 patients. Four cases were homogeneous, 3 cases were relatively homogeneous and 1 case was heterogeneous. All 8 cases showed increased vascularity. The mass lesion was iso-signal intensity on T1-weighted image and low-signal intensity on T2-weighted image. All four cases were enhanced homogeneously and mildly than enhancing normal testicular parenchyme. On dynamic enhancement study, the mass lesion is progressively enhanced with time. CONCLUSION: The possibility of testicular lymphoma should be considered when testicular mass was homogeneously hypoechoic and low signal intensity on T2-weighted image in old age patients.

Case Reports

Intratesticular Simple cyst lined by ciliated columnar epithelium: A Case Report.: Ji Yoon Kim, Hwa Soo Lim, Ki Hak Moon, Mi Jin Kim, Jae Ho Cho; Yeungnam Univ J Med. 2005;22(2):266-269. Published online December 31, 2005; DOI: https://doi.org/10.12701/yujm.2005.22.2.266

Abstract PDF: An intratesticular simple cyst is a rare lesion. The pathogenesis of such lesions is uncertain. Clinically, an intratesticular simple cyst may be difficult to differentiate from a cystic neoplasm. However, preoperative diagnosis is possible using ultrasonography (US). Testis-sparing surgery with simple enucleation of the cyst has a favorable outcome. We report an intratesticular simple cyst in a 48-year-old male who had a non-tender cystic mass in the right testis for 2 years. The diagnosis was made by preoperative US. The patient underwent a testis-sparing surgery. After simple excision of the cyst, histological examination revealed a simple cyst lined by ciliated cuboidal and columnar epithelium.

A Case of Bilateral Testicular Teratoma Found in Infant.: Un Gi Baek, Seok Young Chung, Woo Seok Choi, Phil Hyun Song, Chul Kyu Cho, Ki Hak Moon, Dong Sug Kim; Yeungnam Univ J Med. 2003;20(1):92-98. Published online June 30, 2003; DOI: https://doi.org/10.12701/yujm.2003.20.1.92

Abstract PDF: Testicular teratoma is characterized that has more than one germ cell layer in various stages of maturation and differentiation. The incidence of mature teratoma varies from 2 to 9% of all germinal testicular tumor. Only 3 cases of bilateral teratoma have been reported in the literature to date. The teratoma can occurs at all ages but is most common between the age of 15-35 year. It is relatively infrequently seen in childhood and infancy. In these age group, teratoma tends to be a benign. Recently, we experienced one case of bilateral testicular teratoma in 4 month-old infancy. We report a case of bilateral testicular teratoma found infancy with review of related literatures.
