All right, welcome. My name is Devine. This is episode 473 of the Devine Intervention

Podcast. In today's podcast, I'm going to be continuing the rapid review series for the

USMLE Step 2, Step 3 exams. This is going to be Series 99.

Series 99.

Okay, so what if they give you a question about a seven-year-old girl, they tell you that for the past two weeks, her parents have been

noticing that she has been having like really bad headaches in the mornings and they tell you that

she has also noted they've also noticed some weakness in her extremities and then you're told that they obtain imaging and you know you get

the imaging I see like a big cerebellar mass in fact whenever the US

is presented this concept they say oh they show you big cerebral amass.

And in addition to that, you see some lesions, you give you like a, you know, like a sajunovial

of the spinal cord, I see all these white white lesions in the spinal cord.

And one of the classic cancers they're going to throw your ways, MS. They put multiple sclerosis as an

answer. And then you put milleublastuma as an answer, then a bunch of other fluff.

And you see something like this, I really hope you're thinking of a meleoblastoma.

Okay, think of a meleblastoma.

So maybe like, okay, divine, so how do I differentiate this from MS? Well the thing is this

MS does not cause a cerebellar mass right because MS can cause brain lesions and it can also brain lesions in the spinal cord. That's why many times

when we're diagnosing multiple sclerosis or do an MRI of the brain and spinal cord.

But the thing is MS does not cause a cerebellar mass so this

person has been a low blood stomach you may be like divine like but why are you

not saying this is one of the other cerebellum masses that can happen in kids like a

a pilocythrocytoma or a hymanjoblastoma or something like that.
