Neuro_MR_Brain: 53 M, neuroendocrine tumor, evaluate for mets
MRI BRAIN WITH AND WITHOUT CONTRAST:
CLINICAL HISTORY: 52-year-old man with history of neuroendocrine tumor, on anticoagulation, evaluate for hemorrhage or intracranial metastasis. Also history of anoxic brain injury after suicide attempt by hanging 20 years ago.
Ventricles and extra-axial spaces: Ventricular prominence commensurate with global volume loss.
Visualized paranasal sinuses: Mild mucosal thickening in the ethmoid air cells and right frontal sinus.
Mastoid air cells: Clear.
Bones: Diffusely heterogeneous bone marrow without focal lesion.
Additional comment: None.
1. Multiple (greater than 20), ring-enhancing lesions in the supratentorial and infratentorial brain, with central restricted diffusion, favored to represent abscesses given diffusion pattern and extensive lung infection with pulmonary vein thrombosis as likely source. Correlation with CSF analysis would be useful. Also consider atypical organisms (e.g. fungal). Follow-up recommended as smaller lesions without central cavitation would be impossible to distinguish from superimposed metastases. No evidence of hemorrhage or mass effect.
(Diffuse cerebral abscesses)
