CTICasesHigh-grade liposarcoma of the pectoralis muscle
Imaging findings
CT shows a large, predominantly fatty intramuscular mass in the pectoralis major muscle containing nodular, ground-glass, and fibrotic non-adipose soft-tissue components.
Key takeaways
While simple lipomas are common and benign, the presence of thick septa, nodular soft-tissue components, or non-lipomatous ground-glass areas within a fatty muscle mass should raise concern for liposarcoma.
