Abstract:
Objective To summarize radiographic manifestations of granulocytic sarcoma (GS),in order to investigate its radio-graphic feature.Methods Nine patients of GS confirmed by surgery pathology and immunohistochemistry were collected.There were four cases underwent CT scan,2 underwent MRI,3 underwent CT and MRI meanwhile.Results There were 4 cases in the lymph nodes,4 cases in the bone,1 case in the enterocoelia.The density of enlarged lymph node was inhomogeneous,and smaller lymph node was homogeneous density,both enhanced obviously.The density or intensity of the lesions occurred in the canalis verteb-ralis and paravertebra was also homogeneous,slightly enhanced,with bone and medulla ossea invasion.Lesions in the enterocoelia was inhomogeneous desity with clear boundary,enhanced inhomogeneously.Conclusion GS is a rare extramedullary malignant tumor composed of immature myeloid cells.CT and MRI can provide a certain diagnostic value.The perplexity in diagnosing such lesions highlighted the need of careful interpretation of all clinacal,radiographic,histopathological and immunochistochemical details as it is one of the most frequently misdiagnosed disorder.
