Main et al were successful in producing cholesterol granulomas
in squirrel monkeys by obstructing the eustachian tube for 6 to 12 months.
MRI offers the superior soft-tissue differentiation that is necessary to distinguish between cholesteatoma, cholesterol granuloma
, and intracranial suppurative complications.
Congenital cholesteatoma and cholesterol granuloma
of the temporal bone: role of magnetic resonance imaging.
The mastoid portion was found to be filled with a dark purple tumor that was thought to represent cholesterol granuloma
. The cyst wall of the cholesterol granuloma
was very thick.
in the maxillary sinus, as reported in our cases, is a histologic finding associated with clinical symptoms of inflammatory diseases such as rhinitis and sinusitis [3,9].
is a fibrogranulomatous lesion that develops secondary to a foreign body reaction to cholesterol crystals and exhibits the accumulation of foreign body giant cells.
Endoscopic sinus surgery in cases of cholesterol granuloma
of the maxillary sinus.
We report on 2 patients with petrous apex cholesterol granulomas
who presented to the Division of Otolargynology and were treated at the UCT Private Academic Hospital, Cape Town.
Thus, cholesterol granuloma
is a foreign-body reaction to Cholesterol Granuloma
of Maxillary Sinus--Leon et al 217 the presence of cholesterol crystals formed during the inflammatory process.
MRI shows a classic hyperintense signal on both T1- and T2-weighted imaging, and this is pathognomonic for a cholesterol granuloma
. (5) Occasionally, a cholesterol granuloma
will demonstrate an area of hypointensity on MRI as a result of a solid mineral content within the cyst.
Phospholipids in atherosclerosis: the modification of the cholesterol granuloma
We report the unique finding of a petrous apex cholesterol granuloma
associated with a paraganglioma, also known as a glomus jugulare tumor, in a 52-year-old woman who presented to our department with pulsatile tinnitus, hearing loss, aural fullness, and disequilibrium.
