Abstract:Cholesterol granuloma (CG) is usually associated with chronic middle ear disease, and is not common in the paranasal sinuses. Additionally, it is very rare for cases of CG to be associated with a fungal infection. However, in this paper, we report a case of sphenoid sinus CG that is associated with aspergilloma in a 78-year-old male patient who presented with right hemifacial pain, headache and toothache. CT revealed the presence of an expansile cystic mass lesion in the sphenoid sinus that showed a high signa… Show more
“…Cholesterol granulomas are seen with high signal intensity on both T1-and T2-weighted MRI images, related to the paramagnetic effect of methaemoglobin and granulations (11). Although mucoceles with high concentrations of protein may appear similar to cholesterol granulomas on…”

“…5 Although mucoceles with high concentrations of protein may appear similar to cholesterol granulomas on T1-weighted MRI images, mucoceles have a lower signal intensity on T2-weighted scans, compared with cholesterol granulomas. Similarly to our case, the association of cholesterol granulomas and aspergilloma within the maxillary sinus has been reported.…”

“…Similarly to our case, the association of cholesterol granulomas and aspergilloma within the maxillary sinus has been reported. 5,6 Cystic schwannomas involving the sphenoid sinus are very rare. 7 Depending on the degree of cystic degeneration, cystic schwannomas show variable enhancement on contrast-enhanced CT and MRI scans.…”
Although an association between a fungus ball and a mucocele is rare in the paranasal sinuses, this disease entity should be considered in the differential diagnosis of expansile, cystic sinus lesions.
“…[1] Barring a very few small series, majority of the published primary spinal cord GBMs are isolated case reports. [2,3] Although GBM is the most common primary brain neoplasm in adults and makes up almost 50% of all astrocytic tumors, they are exceptionally rare in the spinal cord, amounting to only 3% of all intramedullary tumors. [1] The relatively low proportion of absolute number of neuroglial cells (as compared to brain) in the spinal cord probably accounts for the rarity of these neoplasms in the spinal cord.…”
“…CG of the sphenoid sinus has rarely been reported. [1][2][3] Symptoms of CG are usually related to the pressure effect on the adjacent structures. Rarely, CG of the sphenoid sinus can present with gradual loss of vision.…”
