Arteriovenous malformation of the choroid plexus

Abstract

A case of a 55-year-old female with arteriovenous malformation (AVM) of the choroid plexus within the right ventricle is reported. Arteriovenous malformation of the choroid plexus is a rare occurrence. The MR findings of this malformation are discussed.

Intraventricular vascular malformations mimicking tumors: Case reports and review of the literature

“…Fourth, cryptic vascular malformations commonly lacked typical characteristics and could mimic tumors on radiologic studies. Fifth, different vascular malformations coexisted with or accompanied congenital disease [15], and cavernomas, AVMs, and venous angiomas may share some association.…”

“…To our knowledge, 34 intraventricular AVMs, including our two, have been reported [11][12][13][14][15][16][17][18] (Table 1). Intraventricular AVMs most frequently affected adults.…”

“…Therefore, CT was somewhat better than angiography in elucidating the lesion, its anatomic location, and the extent of hematoma if present. MRI offers additional details about the primary lesion, the type of vascular lesion present, and its differential diagnosis [15]. AVMs characteristically have high attenuation on CT scans, low intensity on T1-weighted MRIs, and high intensity with a signal void on T2-weighted MRIs.…”

“…Furthermore, the lesion was supplied by the anterior and posterior choroidal arteries with early drainage into the internal cerebral vein and then to the vein of Galen (Figure 2A ➡ consciousness and increased intracranial pressure due to obstructed hydrocephalus. In some patients, headache was the only symptom 11 . A few patients with intraventricular AVM were asymptomatic and incidentally diagnosed on imaging studies 5 .…”

“…The signal void linear straits belonging to drainage vessels seen on angiography give a clue to AVM (Fig.4). Therefore, MRI can be helpful in differential diagnosis of granulomatous or highly vascular neoplastic lesions such as choroids plexus papilloma and carcinoma (Gürcan et al, 1998). …”
