1/The medulla is anything but DULL! Does seeing an infarct in the medulla cause your heart to skip a beat? Does medullary anatomy send you into respiratory arrest? Never fear, here is a thread on the major medullary syndromes!

1/Is remembering cerebellar anatomy making you dizzy? Need help telling your flocculus from your nodule? How much cerebellar anatomy do YOU know? Here’s some help w/an anatomy thread on the 9 lobules of the vermis!

Huge thanks to ⁦@UAMS_RIG⁩ for organizing the M4 case challenge!@uamsradiology ⁦@uams_ir⁩

Congratulations to our @uamshealth R4 #RadRes and @uams_ir residents on yet another 100% @ABR_Radiology core exam pass! Wishing you all continued success! @rangapurushoth @theshadowfixer @DrRoopaRam @ArvChoudharyMD @jambhekark @Sateesh_Jay @theAPDR

All things pediatric neuroimaging

Bilateral carotid cavernous fistula on a non-contrast MRA of the head compared to a normal MRA which saturates out signal from stationary tissue and flow in the venous direction. More you see, more you know. #radres #Neurorad #nsgy #MedEd #FOAMrad #MedTwitter

Leaving the hospital this morning, I was moved by this sign I pass every day and barely notice. The tornado devastation in Mississippi is overwhelming. Overnight, @UMMCnews faculty and staff responded to the needs of so many. Amazing people and a most special place!

Dear Patient we have never met, #Radiologists sometimes cry for you and your family, some pray for you, and all of us fight for you. You have more support than you may know. Sincerely, One of your other doctors

Sturge-Weber syndrome (GNAQ mutations): short pictorial review of the imaging findings beyond pial angioma #pediNeuroRad

Tip of the day 💡: None of this is to be construed as abnormal enhancement. When a good contrast bolus is shot through all the normal vessels light up, even in that arrowed pontomedullary and high cervical region.

#OnePediNeuroRad 🌍 Don´t forget superior vermis as target lesion of hypoxic - ischemic encephalopathy. Best seen in chronic stage as focal volume loss. I ´ ll give you a differential based only on superior cerebellar atrophy: ITPR1-Related Disorders

Tip of the day 💡: Sometimes one has to zoom in to the superior cerebellar vermis to pick up “dysfoliation”- this may be the only abnormality, and is often associated with a genetic disorder- a KIF mutation in this case. Did you appreciate the disordered folia with small cysts?

Talk about seeing red! Vitreous blood w/large subarachnoid hemorrhage--it's NOT intracranial SAH dissecting along the optic sheath It's from sudden⬆️intracranial pressure causing central retinal vein obstruction=hemorrhage, called Terson's syndrome. Poor prognosis #NeuroTwitter

Working w/fellows always keeps you honest! My fellow asked why the whole thalamus doesn't infarct w/PCA occlusion. We had to look it up Answer:Blood supply is both from PCA & PCOMM (ICA) Here's the anatomy #neurotwitter #stroke #radres #neurology #neurorad #meded #medtwitter

Infant with brachial plexus injury at birth T2 MRI shows left sided extradural CSF collection posterior to spinal cord from C6 to T1. The diagnosis was avulsion pseudomeningocele with possible avulsion of the C7 nerve root #FOAMed #FOAMPed #FOAMRad #PedsRad #RSNA22 #RadEd

Tip of the day 💡: 2 episodes of encephalopathy- first and second image 1 year apart. In a young child with recurrent attacks, especially in the context of ANEC, the mutation to check for is RANBP2. Tested positive!

Teen with fever+mental status changes CT with contrast shows ring enhancing lesions in anterior horn of left lateral ventricle+faint enhancement of ependymal lining of ventricles. There is hydrocephalus present as well as effacement of basilar cisterns #FOAMed #FOAMPed #FOAMRad

Do not mistake pars intermedia cysts for pituitary adenomas. They are a common incidental finding, with simple or proteinaceous cyst content, located in between the pars distalis and pars nervosa, without mass effect or suprasellar extension. #radres #Neurorad #Neurosurgery #nsgy
