| Diagnosis | Giant Tumefactive Perivascular Spaces | |
| History | 74 year old women with history of shunt placement many years ago for hydrocephalus. New complaints of "dizziness" prompted an MRI. She has numerous prior MRI and CT scans for comparison, dating back 11 years. | |
| Findings | Large,non-enhancing, "cysts" in the right Thalamus, Midbrain and Pons. These contain fluid-like material that tracks with CSF signal on T1, T2, and FLAIR. They have been stable over 10 years. | |
| Differential Dx | • Cysticercosis • Cystic glioma • Encephalomalacia • Tumefactive perivascular spaces • Cryptococcosus | |

| Diagnosis | Tumefactive Demyelination (Multiple Sclerosis) | |
| History | This 33 y.o. man presented with right eye blindness 4 months ago and was diagnosed with MS. He had another episode of left arm and leg weakness and left eye blindness two weeks ago. | |
| Findings | Expansile (infiltrative?) mass with high signal on T2 and FLAIR involving the right midbrain, pons and extending into the right thalamus and basal ganglia. Minimal peripheral enhancement noted. Lesion is associated with marked mass effect and edema. | |
| Differential Dx | • Astrocytoma • Oligodendroglioma • Abscess • Inflammatory demyelination | |

| Diagnosis | Giant Tumefactive Perivascular Spaces | |
| History | A 47 year-old woman presented with headache, left hemiparesis, paresthesia, diplopia, and dizziness. She also reported difficulty with bladder control in the past year and difficulty swallowing. | |
| Findings | There are multiple septated cystic lesions in the midbrain and pons. These lesions do not enhance and are isointense to CSF on all pulse sequences. There is mass effect with compression of the third ventricle. There is enlargement of the lateral ventricles consistent with obstructive hydrocephalus. | |
| Differential Dx | • Giant Tumefactive Perivascular Spaces • Benign cystic neoplasm • Neuroepithelial (ependymal) cysts • Neuroglial cysts • Old lacunar infarcts • Neurocysticercosis • Cryptococcosis • Mucopolysaccharidoses | |

| History | A 20 year old woman with left sided upper and lower extremity weakness 2 weeks ago who is currently asymptomatic. | |
| Findings | There is a T2 hyperintense lesion within the right corona radiata that demonstrates smooth and homogeneous enhancement on the post gadolinium images. There is some associated edema but no significant mass effect. | |

| Diagnosis | Tumefactive Multiple Sclerosis | |
| History | 20 year-old woman with left side upper and lower weakness 3 weeks ago. Now asymptomatic. Seen by hometown ER, CT scan negative. Evaluated by MRI 1 week ago which demonstrated an enhancing brain lesion. Please reevaluate. | |
| Findings | Within the right corona radiata, there is continued presence of a T2 and FLAIR hyperintense lesion, which displays interval slight decrease in size and clarity of margins. Additionally, there is no longer post-contrast enhancement of the lesion. Gray matter/white matter differentiation is, otherwise, preserved throughout. Prior study dated 1 week earlier shows T2 high signal within the corona radiata and a smoothly uniform enhancement pattern likely represent a demyelinating plaque (Tumefactive multiple sclerosis). | |
| Differential Dx | • Tumefactive MS • GBM • Primary CNS Lymphoma | |
