#FOAMrad #neurorad Prominent Inferior Intercavernous Sinus (IICS): A Sign of Intracranial Hypotension (SIH) Dilatation of the IICS is frequently associated with SIH, although it can also be found in the healthy adult as a normal anatomic variant.

#FOAMrad MRI Signs of Intracranial Hypotension Coronal: Venous engorgement of SSS (1) Pachymeningeal enhancement (2) Superficial siderosis (3) Enlarged pituitary gland (4) Prominent intercavernous sinus (5) Effaced suprasellar cistern (6) Subdural fluid collection (7)

CSF leak classification The syndrome of spontaneous intracranial hypotension (SIH) is generally caused by leakage of CSF from the thecal sac within or along the spinal canal The authors categorized the CSF leaks into 4 types based on the morphology and distance from the midline

MRI nonhemorrhagic markers of Cerebral Small Vessel Diseases Arteriolosclerosis: Severe (>20) enlarged perivascular spaces (EPVS) located in the basal ganglia Peribasal ganglia pattern of WMH following the peripheral outline of the basal ganglia Lacunes in the basal ganglia
