Liposarcoma is a soft tissue tumor that commonly appears in the retroperitoneum and the extremities. Herein, we presented the imaging findings of a 68-year-old man with a paravertebral liposarcoma involving the adjacent vertebral bodies, appendices, and ribs. MRI revealed this mass located in the left side of T9 to T10 vertebral bodies. FDG PET/CT demonstrated the mass with intense FDG uptake. Finally, the pathological findings were consistent with a diagnosis of a primary paravertebral liposarcoma.

UI MeSH Term Description Entries
D008080 Liposarcoma A malignant tumor derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (LIPOSARCOMA, MYXOID), round-celled, or pleomorphic, usually in association with a rich network of capillaries. Recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces.

D000072078 Positron Emission Tomography Computed Tomography An imaging technique that combines a POSITRON-EMISSION TOMOGRAPHY (PET) scanner and a CT X RAY scanner. This establishes a precise anatomic localization in the same session.

D012983 Soft Tissue Neoplasms Neoplasms of whatever cell type or origin, occurring in the extraskeletal connective tissue framework of the body including the organs of locomotion and their various component structures, such as nerves, blood vessels, lymphatics, etc. Neoplasm, Soft Tissue,Neoplasms, Soft Tissue,Soft Tissue Neoplasm
D049268 Positron-Emission Tomography An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower.

D019788 Fluorodeoxyglucose F18 The compound is given by intravenous injection to do POSITRON-EMISSION TOMOGRAPHY for the assessment of cerebral and myocardial glucose metabolism in various physiological or pathological states including stroke and myocardial ischemia. It is also employed for the detection of malignant tumors including those of the brain, liver, and thyroid gland.
