Plain-English summary
A six-year-old male Pomeranian was having repeated seizures and was getting weaker on one side of his body. An MRI scan showed a mass in the brain that looked bright on certain images, which suggested it was a meningioma, a type of tumor that can occur in the protective layers of the brain. The mass was surgically removed, and the examination of the tissue confirmed it was indeed a meningioma. The tumor had a lot of cells and some bleeding, but there were no signs of calcification. The treatment involved surgery, and it was successful in removing the tumor.
Abstract
A male six-year-old Pomeranian showed recurrent seizures and progressive left hemiparesis. MRI revealed a mass in the right paramedian frontal-temporal region with hyperintensity on T1-weighted (T1W) and mixed-intensity on T2-weighted (T2W) images. After gadolinium enhancement, the mass was enhanced homogenously and demonstrated the dural tail sign. Surgical resection of mass was performed and its histological diagnosis was meningioma. The meningioma of this case had a high cellular density with some lipid contents and intra- and extra-tumor hemorrhage, however, calcification was not found. These cellular characteristics may contribute to a higher signal intensity on T1W imaging.
