ABSTRACT
Objective To explore the CT and MR imaging characteristics of intracranial melanomas. Methods CT and MRI characteristics in five patients admitted to our hospital from June 1993 to June 2000 and diagnosed as intracranial melanomas were retrospectively analyzed. Results There were two cases of primary melanoma and three cases of secondary melanoma. All the cases were examined by CT. The lesions presented as high density in 4 cases, and low density in only 1 case. Four cases were examined by MRI. Short T 1 and short T 2 signals were found in 3 cases, and slightly long T 1 and short T 2 signal was found in 1 case. Conclusion There are some special characteristics of melanomas on the MR imaging, which are helpful to ensure the diagnosis and distinguish the primary melanomas from secondary melanomas.
