Pathologic studies have shown that the high T1 signal of vertebral hemangiomas is related to the presence of fatty stroma, whereas the vascular component of the lesion is mostly responsible for the high T2 signal [ 12 ]. Although typically incidental findings, they are symptomatic in 0.9 to 1.2% of adults [ 1, 2 ]. The majority of the hemangiomas seen with imaging studies are asymptomatic and incidental findings. Fast spin-echo T2-weighted MRI can be helpful in confirming the diagnosis because these lesions are most often T2-hyperintense. Multiple hemangiomas are seen as multiple T1-weighted hyperintense lesions in the vertebral bodies or posterior elements. Normal variations in sellar T1 signal hyperintensity are related to vasopressin storage in the neurohypophysis, the presence of bone marrow in normal and variant anatomic structures, hyperactive hormone secretion in the anterior pituitary lobe (eg, in newborns and pregnant or lactating women), and flow artifacts and magnetic susceptibility effects.

The T2 MRI hyperintensity is often a sign of demyelinating illnesses. Hemangiomas of the vertebral bodies are common benign vascular tumors. A bright spot, or hyperintensity, on T2 scan is nonspecific by itself and must be interpreted within clinical context (symptoms, why you had the MRI done in the first place, etc). A nodular zone of abnormal signal intensity is identified involving the marrow cavity of the anterior inferior aspect of the T2 vertebral body consistent with a focal hemangioma of the bone. T3, T4, and T5 feed into the chest wall and aid in breathing. This can happen from chronic high blood pressure, smoking, excessive alcohol use, and other factors.
