introduction: orthogonal radial fields are those in which the central axes are perpendicular to each other. an example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. the m...

objective: to report involvement of the central nervous system (cns) following epithelial ovarian cancer is rare. advances in management of ovarian cancer by use of primary surgery including abdominal hysterectomy, bilateral salpingo'oophorectomy should attain as complete a cytoreduction as possible and effective platinum-based chemotherapy have prolonged survival. case report: we present a cas...

BACKGROUND   Radiosurgery is being increasingly used post craniotomy for brain metastasis, instead of whole-brain radiation. We report a case of scalp metastasis following craniotomy and radiosurgery, along with a systematic review of the literature. METHODS         Our patient was a 70-year-old male who presented with a scalp metastasis, two years after craniotomy and radiosurgery, for a sol...
