Fig 2: Thoracic intramedullary PMA extending from
T6 to T8 vertebral body. a ) Sagittal T2w weighted (MRI) showed
hyperintense lesion. b ) Sagittal T1w weighted (MRI) showed
hypointense lesion.
Since PMA is a recently discoverd tumor, reported cases in the literture
suggesting difficulty distinguishing radiological imaging features for
this extermly rare tumor compare to PA [10] . On the other hand, the
histological finding of PMA has dependable difference features compared
to PA [3].
