Arteriovenous malformations (AVMs) represent an abnormal leash of vessels through which there is arteriovenous shunting. They can occur anywhere in the body, with the shoulder being one of the less common sites.  AVMs may be slow or high flow, as in this case.  This is a real whooper of a high flow AVM in the deltoid muscle, with arterial supply from a very generously proportioned subclavian artery.  https://radiopaedia.org/cases/high-flow-arteriovenous-malformation-of-the-shoulder Subclavian Artery, Deltoids, Mri, Abnormal, Arteries, Gaga, Surgery, Flow, Common

Osteosarcomas are malignant bone forming tumours and the second most common primary bone tumour after multiple myeloma. They account for ~20% of all primary bone tumours and occur in primary and secondary forms, each with different epidemiology and distribution. Although plain radiography can provide a lot of information, MRI is used for local staging by assessing intraosseous tumour extension (e.g. growth plate/epiphysis) and soft-tissue-involvement.

Intracranial epidermoid cysts are relatively common congenital lesions which account for about 1% of all intracranial tumours. They result from inclusion of ectodermal elements during neural tube closure, and typically present in middle age due to mass effect on adjacent structures. Their content, derived from desquamated epithelial cells, mimics CSF on CT and MRI, with the exception of DWI which demonstrates restricted diffusion.  http://radiopaedia.org/articles/intracranial-epidermoid-cyst Epidermoid Cyst, Dwi, Restricted, Middle Age, Neuro, Head And Neck, Inclusion, Exception

White cerebellum sign (also called reversal sign or dense cerebellum sign) is encountered when there is a diffuse decrease in density of the supratentorial brain parenchyma, with relatively increased attenuation of the thalami, brainstem and cerebellum. This sign indicates irreversible brain damage and has a very poor prognosis, which is why radiologists must be aware of this sign.  http://radiopaedia.org/articles/white-cerebellum-sign Brain Injury, Nerdy Nurse, Signs Of Dementia, Human Body

Lhermitte-Duclos disease (LDD), also known as dysplastic cerebellar gangliocytoma, is a rare tumour of cerebellum. It is probably hamartomatous, although the exact pathogenesis remains unknown.  The abnormal tissue involves the cerebellar cortex, and is usually confined to one hemisphere, occasionally extending to the vermis but only rarely extending to the contralateral hemisphere.  http://radiopaedia.org/articles/lhermitte-duclos-disease Medical Education, Medical Science, Medical School, Magnetic Resonance Imaging, Chaos Chaos, Renal Cell Carcinoma, Parotid Gland

Central pontine myelinolysis (CPM) (also known as osmotic demyelination) refers to acute demyelination of the white matter tracts traversing the pons. It seen in the setting of osmotic changes, typically with the rapid correction of hyponatraemia. Despite the name extrapontine structures can also be affected: basal ganglia, midbrain and subcortical white matter. It is then known as extrapontine myelinolysis (EPM).   http://radiopaedia.org/articles/central-pontine-myelinolysis Rayon X, Basal Ganglia, Homeschool Science

Fibrous dysplasia (FD) is a non-neoplastic tumour-like congenital process, manifested as a localised defect in osteoblastic differentiation and maturation, with replacement of normal bone with large fibrous stroma and islands of immature woven bone.  Fibrous dysplasia is found predominantly in children and young adults, with ~75% of patients presenting before the age of 30 years.  Upto 25% occurs in the face and skull.  http://radiopaedia.org/articles/fibrous-dysplasia Bone Diseases, Nerve Palsy, Dr Ian, Facial Nerve, Neurology

Left venticular aneurysms are discrete, dyskinetic areas of the left ventricular (LV) wall with a broad neck (as opposed to left ventricular pseudoaneurysms), thus often termed true aneurysms.  Aneurysm formation occurs when intraventricular tension stretches the non-contracting infarcted myocardium, causing bulging of the infarcted area with each contraction.  http://radiopaedia.org/articles/left-ventricular-aneurysm Cancer Fighting Smoothies, Cancer Fighting Foods, Coarctation Of The Aorta, Tetralogy, Signs Of Lung Cancer, Lung Cancer Awareness, Mesothelioma, Shortness Of Breath
