The "botryoid sign": a characteristic feature of rhabdomyosarcomas in the head and neck.

abstract：:We describe an atypical MRI appearance of multiple sclerosis (MS). Lesions characterized on T2-weighted images by a well-defined rim of increased signal intensity and a concentric region of higher signal intensity were seen in 6 of 132 patients with MS. On T1-weighted images these lesions were evident as regions of lo...
