The CT and MR findings are reported in a case of biopsy proven rhabdomyosarcoma of the skull base. The tumor presumably originated in a pneumatized petrous ridge and had an atypical presentation of multiple cranial nerve palsy. The lesion exhibited a soft tissue density and a nonexpansile bone destruction on unenhanced CT. On MR imaging the lesion showed homogeneous intermediate signal intensity on T1 weighted images and a high signal intensity on proton density and T2 weighted images. The scanty literature on CT and MR features of rhabdomyosarcoma of the head and neck is reviewed.
本文报告了一例经活检证实的颅底横纹肌肉瘤的CT和MR表现。肿瘤可能起源于气化的岩骨嵴，表现为非典型的多组颅神经麻痹。平扫CT上病变呈软组织密度，骨质破坏无膨胀性。MR成像上，病变在T1加权像上呈均匀等信号，在质子密度加权像和T2加权像上呈高信号。本文还复习了关于头颈部横纹肌肉瘤CT和MR特征的少量文献。
