Histological examination demonstrated the closely apposed vascular channels characteristic of cavernous angiomas. Although total eradication of the hemangioma is not possible with this technique, there seems to be no risk for new hemorrhage. In all patients, MRI revealed well-delimited right para-sellar lesions, uniformly isointense in T1-weighted images and hyperintense in T2- T2- and FLAIR-weighted images, brightly enhancing after intra-vascular infusion of gadolinium.
No other hemorrhage-associated symptoms, such as abdominal pain, fever, consumptive syndrome, or anemia developed.
KRIT1 has been shown to act as a transcription factor in the development of arterial blood vessels in mice. Additionally, research on hemangiomas in general has shown that loss of heterozygosity is common in tissue where hemangioma develops. The gliomatous nature of the tumor was pathologically obvious, although in some points of the tumoral mass it was nearly ajgioma from this particular architecture of the vascular cabernoso Fig 2abc. Because of the high mortality when attempting to remove these lesions, radiologists should alert surgeons for this possibility.
Steroids can be taken orally or injected directly into the tumor.
J Neurosurg ; This allows for tumor shrinkage and less pain. Complete surgical excision of the lesion with a sphincter-saving procedure is the primary mode of treatment: Crowel 4Nazek 12 and Lombardi 10suggested that an exaggerated glial proliferation could be a reactive response to any anhioma of AVM, with subsequent chronic ischemia and white matter changes.
