Unusual Intraventricular Tumor Mimicker; Choroid Plexus Arteriovenous Malformation
1Department of Radiology, Faculty of Medicine, Ataturk University, Erzurum, Turkey.
Abstract:
Arteriovenous malformations (AVMs) are basically abnormal vessel networks consisting of one or more feeding arteries, central nidus, and dilated drainage veins. They are divided into subtypes as fistulose, mixed (fistulose-plexiform), or plexiform. Intraventricular location of AVMs is unusual. In this location, the lesion may mimic neoplastic processes. Here the authors reported uncommon case of an AVM located in the right choroid plexus presenting with intraventricular hemorrhage.

Unusual Results
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
