CT findings in paravertebral synovial sarcoma.

Area of Science:

• Oncology
• Radiology
• Pathology

Background:

• Synovial sarcoma is a rare soft tissue sarcoma that can occur in various locations.
• Paravertebral locations, such as cervical and lumbar spine, are uncommon sites for this tumor.
• Computed Tomography (CT) is a key imaging modality for soft tissue mass evaluation.

Observation:

• Two patients presented with paravertebral synovial sarcoma in the cervical and lumbar regions.
• Soft tissue masses in both patients demonstrated calcifications on CT imaging.
• One patient exhibited an atypical metastatic pattern involving the pancreas.

Findings:

• Calcifications within paravertebral synovial sarcoma masses can be a CT finding.
• Pancreatic metastasis from synovial sarcoma is an unusual presentation.
• This case series underscores the diverse clinical and radiological manifestations of synovial sarcoma.

Implications:

• Radiologists and oncologists should consider synovial sarcoma in the differential diagnosis of calcified paravertebral soft tissue masses.
• Awareness of unusual metastatic sites, like the pancreas, is crucial for comprehensive patient management.
• Further research into the patterns of metastasis in synovial sarcoma may improve diagnostic accuracy and treatment strategies.
