Spectrum of cystic-appearing soft-tissue tumors. (a) Axial contrast-enhanced CT image in a 62-year-old woman with a palpable abdominal mass shows a large thick-walled multi­loculated cystic mass (*) with septa (arrowhead) and solid nodu­lar components (arrow). It was pathologically confirmed to be dedifferentiated liposarcoma with myxoid components, which corresponded to the cystic spaces. (b) Coronal contrast-enhanced CT image in an 18-year-old woman with abdominal distention and pain shows a massive predominantly solid mass with several cystic components (*). At histopathologic evaluation, the cystic components corresponded to areas of myxoid stroma within a spindle cell tumor, consistent with desmoid tumor. Desmoid tumors have invasive properties and tend to damage blood vessels.
