Analysis of surgical treatment for middle-ear cholesterol granuloma
Based on these findings, the final diagnosis was a cholesterol granuloma
of the paratesticular tissue.
(CG) is a histopathologically used term which describes numerous cholestrol clefts that are often surrounded with foreign-body giant cells, foam cells and macrophages filled with haemosiderin.
and giant cholesterol cysts (GCCs) of the petrous apex are rare lesions of the temporal bone.
The histopathologic findings were consistent with cholesterol granuloma
In this article, the author describes a new case of petrous apex cholesterol granuloma
to illustrate the definitive need for an extended middle fossa approach when a bilobed petrous apex mass is encountered.
The pathogenesis of petrous apex cholesterol granuloma
The MRI identified the posterior lesion as a cholesterol granuloma
and the anterior mass as a cholesteatoma pearl (figure 2, A).
Extradural cholesteatomas must be differentiated from squamous cell carcinoma (which has malignant squamous epithelium) and cholesterol granuloma
(which contains cholesterol clefts).
Culture and histology of the sinus contents detected evidence of a cholesterol granuloma
but no fungal material.
They are especially helpful for chronic mucoid otitis media, which if not treated with a ventilation tube can progress along a continuum leading to chronic otitis media and chronic mastoiditis characterized by granulation tissue, cholesterol granuloma
, and/or cholesteatoma.
in the absence of physical trauma to the membrane) or in association with chronic otitis media as a result of the formation of granulation tissue or a cholesterol granuloma
Without a supportive history, a blue eardrum in the presence of a cholesterol granuloma
can make the differential diagnosis difficult.
Thick fluid with gold-yellow specks was aspirated, and a diagnosis of a cholesterol granuloma
On imaging studies, each patient had a different pathologic lesion that involved the endolymphatic sac or duct: patient 1 had a jugular megabulb, and she was ultimately treated with vestibular nerve section; patient 2 had a cholesterol granuloma
, which was treated with surgical excision; patient 3 had an endolymphatic sac tumor that was treated with surgical excision.
