 So in this case, I'm going to show, share with you T2-weighted image, a 55-year-old female and T1. So let's see the T2-weighted image. So a lot going on in the pancrease here. And it may be of some utility to look at some other organs in this instance, particularly the kidneys and maybe adrenal glands as well. I'll give you the T1-weighted images. So no real T1-hyperintense content in some of the stuff that we're looking at. Then the post-contrast sequences through the pancrease, a little bit of motion here. Apologize for that. Again, look at the other organs as well. A lot of stuff going on in the other, some of the other organs. This is less motion here, so this may be easier for you to look at. The pancrease looks certainly very interesting, but some of the other organs do as well. Okay. Let's pose our last question for the hour. So in this instance, I'm really asking the group to come up with a diagnosis of what they think this patient has. Based on that, asking you to maybe take it a step further. What's the most common CNS tumor seen in the disease that this patient has? Is it a hemangioblastoma? Is it a neurofibroma? Is it a GBM? Or a sub-dependable giant cell astrocytoma known as SEGA tumors, I believe. I'm certainly no neurologist, so if there's a neurologist out there on the call, you know, you feel free to educate me a little bit if I'm incorrect about any of these things. Yeah, so hemangioblastoma. So it was the most, it was the correct answer as most people get. So what am I showing you here? So you're seeing a pancrease that is, you know, replaced by numerous, numerous cysts. And when you see that appearance, you've got to think of Vaughan-Hippo-Lindau disease. Now it's a rare disease. We see it in a select few patients. It's a redditary, autosomal dominant, and it affects multiple organs resulting in multiple neoplasms. Now in the pancreas, you're going to see a bunch of cysts. Now these, unlike other, you know, cysts in the pancreas, tend to be true epithelial cysts. So with an epithelial lining, true cysts in the pancreas. You also see cirrhosis adenomas. We know what that looks like now, and it's, you know, it's very tough to know if some of these are true cysts, or some of this could represent a cirrhosis adenoma. Exactly true cysts and cirrhosis adenomas are benign, so we don't worry about them. The one thing you can see in these patients are neuroendocrine tumors as well. And so you need to be on the lookout, particularly in your post-contrast sequences, to make sure you're not dealing with any neuroendocrine tumors, because of course those are something that we need to worry about. But besides that, you see disease in other organs, and the kidneys here, these patients had partial nephrectomies, but you can see there's multiple renal neoplasms, which is characteristic of Vaughan-Hippo-Lindau, multiple bilateral renal neoplasms, that is. You can see a few chromosytoma, which is another finding you can see in patients with Vaughan-Hippo-Lindau. In the epididymis in male patients, you can see cysts or papillaries, cyst adenomas. In the head and neck region, you can see endolymphatic sac tumors. And in the CNS, hemangioblastomas, they can happen in the cerebellum, brainstem. But one area that I always look for is in the spinal cord. So you may end up getting cases where, you know, you're reading the abdomen, look at the spinal cord, and you may just see a, you know, a little focus of enhancement. If you do see that, that's probably going to be a hemangioblastoma. Now, a lot of these patients end up getting dedicated thoracic spine, lumbar spine MR, so you don't necessarily need to make that diagnosis. But, you know, if you have a donobo case, you know, it's good to know where, you know, look at the kidneys, adrenal glands, pancreas, but if you really want to take it to that next level, sort of completing your understanding of the disease and adding value, you know, look at the spinal cord to see if you see any tiny hemangioblastomas as well. They can also get chloride plexus papillomus in the CNS, under the CNS category. So this is a patient with, with von Eppel Lindau gets followed regularly with us to make sure that things are under control and that these neoplasms aren't below.
