SUMMARY

A 46 y/o male patient with a chronic subdural hematoma (CSDH), developing long after a head trauma and an ipsilateral arachnoid cyst (AC), was operated and during the removal of the CSDH a 1x1 cm extracerebral tumor was noticed. The pathologist identified the tumor as a meningioma. A Gradient ECHO MRI sequence raised some suspicions about the finding, and a specimen review reported a fibrous organized CSDH. This paper points to the role of MRI in the diagnosing such intracranial processes.

Key words: chronic subdural hematoma, meningioma, Gradient ECHO MRI, head trauma
