CEUS and ultrasound-guided biopsy are valuable tools for diagnosing rare and aggressive peritoneal malignancies such as desmoplastic small round cell tumours.
Desmoplastic small round cell tumour (DSRCT) is a rare and highly aggressive mesenchymal neoplasm with poor prognosis that develops in male adolescents and young adults. We report the case of a 32-year-old male admitted with abdominal distension and ascites. An ultrasonography (US) scan showed multiple peritoneal masses with large ascites. The dominant mass had a hypervascular homogenous aspect at contrast-enhanced ultrasound with wash-out in the venous phase. Thoracoabdominal CT, performed for staging the disease, confirmed the US aspect. The US-guided percutaneous biopsy revealed DSRCT of the peritoneum. Chemotherapy was then started with minimal clinical improvement, increase in tumoral burden and death after three months. US and US-guided biopsy played an essential role in diagnosing this case. The aggressive course of the disease and seeding at paracentesis sites are the particularities of the presented case.

Spârchez et al. (2022) conducted a case report in Desmoplastic small round cell tumour (DSRCT) (n=1). Contrast-enhanced ultrasound (CEUS) and ultrasound-guided biopsy was evaluated on Diagnosis of DSRCT. Contrast-enhanced ultrasound and ultrasound-guided biopsy successfully diagnosed a rare, highly aggressive desmoplastic small round cell tumour of the peritoneum in a 32-year-old male.
