Abstract
Background:
Liposarcoma (LPS) is a rare type of tumor; they come from the adipose tissue. It is the most common type of soft-tissue sarcoma. Every type of LPS has morphological features, immunophenotypic, and molecular pathogenesis characteristics of their own. In this case, we are going to report a cerebellar metastatic disease from a well-differentiated liposarcoma (WDL) with pleomorphic component, not found in our literature research.
Case Description:
A 72-year-old woman with progressive pain and inflammation in the left knee with functional limitation when climbing stairs. MRI shows a tumor in the vastus medialis of the left thigh. Pathology result was pleomorphic and WDL, Stage III and negative for MDM2 and CDK4. Extension study was carried out, finding nodular lesion in the right cerebellar hemisphere with mass effect and partial obliteration of the fourth ventricle, suspicious of distant disease.
Conclusion:
Cerebellar metastasis of LPS is uncommon; there are only a few cases reports with the literature reviews describing orbital or skull base metastases, but not in the cerebellum. Our case allows us to remember that neurological symptoms, no matter how subtle, in patients diagnosed with LPS, a secondary affectation of the central nervous system must be ruled out, even though it is a rare location. The findings of distant disease in LPSs, allow planning oncological treatment options and targeted radiotherapeutic.
