What is a atypical bony hemangioma on a mri?

Atypical bony hemangiomas on MRI may present as lesions that deviate from the classic imaging characteristics typically associated with these benign vascular tumors. Instead of the usual appearance of well-defined, hyperintense lesions on T2-weighted images and hypointense on T1-weighted images, atypical cases may show unusual patterns such as irregular margins, mixed signal intensity, or associated edema. These atypical features can sometimes lead to misinterpretation, necessitating careful evaluation in conjunction with clinical findings and possibly further imaging or biopsy for accurate diagnosis.
