Patient75 years, male
A 75-year-old male patient presented with history of left lower abdominal pain and palpable left inguinal region mass.
On CECT Abdomen and pelvis: A fairly well-defined spindle shaped elongated soft tissue density lesion of 35-40 HU noted epicentered in left inguinal region along the course of left spermatic cord with no evidence of internal calcifications/hemorrhage/fat component.
On post contrast study the lesion shows heterogenous enhancement with internal non-enhancing areas - suggestive of necrosis.
The lesion shows intraabdominal extension superiorly and extending up to the root of scrotum inferiorly.
The lesion is seen abutting left external iliac veins posterolaterally.
Dilated pampiniform plexus noted extending from inferior pole of the lesion to inferior pole of testis.
Moderate left-sided hydrocele noted.
Leiomyosarcomas of spermatic cord are rare tumors and constitute for 5-10% of soft tissue sarcomas. Leiomyosarcoma constitute for 10% of paratesticular sarcomas.
Leiomyosarcoma results from neoplastic transformation of smooth muscle cells or multi-potential mesenchymal cells. Paratesticular leiomyosarcoma arise from the spermatic cord, the scrotum (testicular tunica, dartos muscle and scrotal sub cutis) or the epididymis [1].
They are most commonly seen in adults with an average age of presentation of 58 years.
Leiomyosarcoma of spermatic cord are most commonly located in the scrotal part of the spermatic cord. In contrast, leiomyoma of spermatic cord are seen in inguinal part of spermatic cord.
On Ultrasonography, leiomyosarcoma appear as heterogenous lesion with predominant hypoechoic area, typically located in the scrotal part of the spermatic cord [2].
On colour Doppler study, the lesions show minimal/increased internal vascularity [1].
On CT Imaging, the lesion appears heterogenous of 25-60 HU with cystic areas with thick and edematous spermatic cord and distended vessels within the cord.
Dissemination occurs by regional lymph node spread, haematogenous metastasis commonly to the lung and local invasion to scrotum, inguinal canal, pelvis and along the path of vas deferens [1].
Locoregional recurrence is commonly seen. Treatment includes transinguinal radical orchiectomy, with adjuvant radiation therapy to reduce recurrence and chemotherapy for high-grade lesions and distal metastases [2].
