Concomitant Presence of Spermatic Cord and Testicular Non-Hodgkin's Lymphoma With Recurrence: A Case Report on a Rare Entity.

Primary testicular non-Hodgkin's lymphoma (PTNHL) with contiguous involvement of the spermatic cord is a rare occurrence and presentation of the disease, and it mostly involves elderly men between the sixth and eighth decades of life. PTNHL is a rare form of primary testicular malignancy that accounts for 1% of all non-Hodgkin's lymphoma cases and 5-10%of all testicular malignancies. This case report discusses a 73-year-old man who presented with right-sided inguinoscrotal swelling for six months, which had progressively increased in size. The patient was referred to the surgical department, and the examination revealed a hard-palpable mass with thickening of the cord. The initial imaging included an ultrasound, demonstrating a heteroechoic mass inseparable from the right testis with evidence of mild increased internal vascularity. Due to the high suspicion of malignancy, a right orchidectomy was performed. The patient subsequently developed another swelling after seven months, over the right inguinal region, which had progressively increased in size. MRI of the pelvis and CT of the abdomen and chest revealed a lobulated, intermediate intense lesion in the right inguinoscrotal region. This case report demonstrates the importance of radiological imaging in assessing and detecting the characteristics of concomitant lesions by using various imaging modalities and assessing the extent of spread. In addition, radiological imaging helps in the early diagnosis of the disease and facilitates prompt and early treatment to achieve favorable outcomes for the patient. The radiologist should include a differential diagnosis of PTNHL when imaging for a painless inguinoscrotal mass.
