Abstract

A rare case of spinal intramedullary granulocytic sarcoma (GS) in a patient with acute myelogenous leukemia is described along with its magnetic resonance (MR) finding. The mass shows isointense signal on T1-weighted images, and slightly higher intensity on T2-weighted images. Contrast enhancement with gadolinium (Gd)-DTPA in this case differs from the other report in which the tumor was not enhanced. As MRI becomes the first choice in the evaluation of spinal tumors, high index of suspicion of GS with familiarity with its MR finding in leukemic patients may obviate the need for surgical intervention, since the tumor is sensitive to both radiation and chemotherapy.

摘要

本文描述了1例急性髓性白血病患者发生脊髓髓内粒细胞肉瘤（GS）的罕见病例及其磁共振（MR）表现。肿块在T1加权图像上呈等信号，在T2加权图像上呈稍高信号。本例钆（Gd）-二乙三胺五乙酸（DTPA）增强表现与另一例肿瘤未强化的报道不同。由于MRI已成为评估脊柱肿瘤的首选方法，因此，对于白血病患者，若高度怀疑GS并熟悉其MR表现，可能无需进行手术干预，因为该肿瘤对放疗和化疗均敏感。
