Mass on scalp: painful, enlarging mass. There are 2 mm thick left superior parietal scalp and 7 mm thick bilateral posterior parietal scalp fat signal lesions. The larger lesion contains a band of low signal, which may a represent fibrous tissue septation. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and mastoid air cells are grossly unremarkable.
Small left parietal scalp lipoma and larger bilateral posterior parietal scalp lesions are compatible with lipomas, although the larger lesion has a more complex appearance.
