Giant XXXX with skull base erosion and extracranial masses: CT and MR findings.

@entity1 @entity439 @entity130 @entity438
OBJECTIVE: To present the CT and MR findings of three @entity1 with @entity438 ( @entity438 ), each of which eroded the skull base and had an extracranial mass component. A literature review of @entity438 was also performed. MATERIALS AND METHODS: In the past year the imaging studies of three @entity1 with these unusual @entity438 were collected at our institutions. All three @entity1 had had CT, and one @entity1 had had MR on a 1.5 T GE unit. RESULTS: One @entity1 had a 5 cm GIA in the left petrocavernous region, filling the middle cranial fossa and extending into the left sphenoid sinus and the left posterior ethmoid complex. The @entity439 had heterogeneous high attenuation and extensive rim calcification. The second @entity1 had a 5 cm GIA that filled most of the left middle cranial fossa, eroding the floor and lateral wall and extending into the infratemporal fossa and parapharyngeal space. The @entity439 was partially thrombosed and had minimal rim calcification. The third @entity1 had a 4 cm left cavernous GIA that eroded the floor of the middle cranial fossa and extended into the subjacent parapharyngeal space. The lesion was partially thrombosed and had an enhancing lumen. The rim had low signal intensity on MR. None of these @entity1 had a history of @entity130 . CONCLUSION: Giant @entity438 can cause significant skull base erosion and extend into the paranasal sinuses, parapharyngeal space, and infratemporal fossa. The CT and MR findings can lead to an accurate diagnosis.
