====== Brain angiolipoma ======

[[Brain angiolipoma]]s are extremely rare and almost all presented observations describe [[sellar tumor]]s. On MRI study brain [[angiolipoma]] may be mistaken for [[pituitary neuroendocrine tumor]] or [[meningioma]] but fat saturation sequences and histological examination clear the diagnosis

In those rare cases when angiolipoma is found in [[cerebral hemisphere]]s, it is important to
establish the diagnosis before surgery to plan correct treatment and avoid [[complication]]s,
particularly profound [[bleeding]]

Shekhtman et al. presented an untypical case of [[frontal lobe]] [[angiolipoma]] manifested with [[seizure]]s and initially described as an [[arteriovenous malformation]].

MRI with a fat-suppression sequence plays a key role in angiolipomas diagnostics.
