%X A variety of neoplastic and nonneoplastic conditions involve the corpus callosum, which may result in a “butterfly” appearance on conventional MRI. Typically, that pattern shows a bilateral and heterogeneous contrast enhancement of the lesion, occasionally with central nonenhancing areas indicating intralesional necrosis. In contrast, anaplastic gliomas may show only minimal or even a lack of contrast enhancement on MRI. We here report neuroimaging findings in a 69-year-old man with a “butterfly” pattern on dynamic FET [O-(2-[18F]-fluoroethyl)-L-tyrosine] PET and the diagnosis of an anaplastic astrocytoma (WHO grade III; IDH-1/−2 wildtype, no 1p/19q co-deletion) but without typical MRI contrast enhancement.
