🖤Melanoma Awareness Month🖤
9) Ocular Melanoma
9a:Uveal melanoma
9b: Conjunctival melanoma
What you should know: Ocular Melanoma, also known as Uveal Melanoma, is a rare eye cancer that develops in the melanocytes of the eye’s choroid, iris or ciliary body.

Choroid Plexus Tumors include:

1) Choroid Plexus Papilloma
2) Atypical Choroid Plexus Papilloma
3) Choroid Plexus Carcinoma

Below is a case of Choroid Plexus Papilloma of the 4th Ventricle

A choroid plexus papilloma can appear as a lobulated, intermediately enhancing intraventricular lesion. Surrounding CSF clefts are often apparent on T2. Hyperperfusion is typically present on cerebral blood volume imaging.

Vascular Parkinsonism (VP) is characterized by rigidity and bradykinesia, predominantly affecting lower limbs. Optical Coherence Tomography (OCT) facilitates visualization of the retina and choroid.

I will wait for clear lens extraction.

Primary angle closure can have several mechanisms involving:

pupil
iris
lens
choroid

To identify whether PAC has lenticular etiology, what do we do??

A choroid plexus papilloma is a benign, lobulated, intraventricular mass arising from choroid plexus epithelium that may disseminate via CSF.

Great Oncopoint symposium by CRIG, where Roos Vandenbroucke and Xenia highlighted our interest in the choroid plexus 🧠🎯

Osteogenesis Imperfecta - Genetic disorder of collagen (in bones/connective tissue) production w/ fragile fracture-prone bones, blue or grayish sclera (thin connective tissue allowing underlying choroid to show), short stature, hearing loss, dental problems

Regular day, looking at this choroid plexus papilloma and then…MELANIN! Do you know why this happen? Does it interferes with the prognosis? #pathTwitter #pathology #pathresidents #neuro 🔬 🧠

Lovely to see these two famous Andrews at #ARVO2024 !
