2024 Friday Quiz 9 Answer

Axial (image 1) and coronal (image 2) T1-weighted, axial T2 weighted (image 3), and axial T1-weighted postcontrast (image 4) MRI show the lobulated mass arising from the glomus of the left choroid plexus. The mass diffusely enhances. Choroid plexus papilloma and choroid plexus carcinoma are the most common choroid plexus tumors. They are most commonly diagnosed in children younger than 5 years of age. Papillomas cannot be reliably distinguished from carcinoma. However, the homogeneous enhancement pattern is more common in patients with papilloma.
