Acute onset left diplopia and left-sided hyperreflexia. History of mesothelioma. The bilateral subdural convexity subdural effusions are not significantly changed and measure up to 1 cm in thickness. They are associated with susceptibility effect indicating the presence of blood products along the inner dural membrane and in other dependent foci. The mild mass-effect on the underlying brain parenchyma is unchanged and there is no midline shift. There is no parenchymal hemorrhage or acute infarct. Minimal diffuse pachymeningeal dural contrast enhancement and thickening might be reactive or may reflect decreased intracranial pressure but there are no other signs of intracranial hypotension. Otherwise, there is is no abnormal intracranial contrast enhancement or mass. The major intracranial arterial flow voids are preserved. The dural venous sinuses are patent.There are small left maxillary retention cysts and mild ethmoid mucosal thickening, which are nonspecific. The orbits are unremarkable.
1.The bilateral convexity subdural hemorrhagic effusions remain unchanged compared to the CT scan from the same day and cause only mild mass-effect on the underlying brain and no midline shift. These bilateral, chronic complex subdural hematomas are of uncertain etiology but intracranial hypotension should also be considered.2.There is no acute infarct, parenchymal hemorrhage, abnormal contrast enhancement or mass.
