RT - Journal Article T1 - Extra-axial medulloblastoma in cerebello-pontine angle: A report of a rare case with literature review JF - MJIRI YR - 2014 JO - MJIRI VO - 28 IS - 1 UR - http://mjiri.iums.ac.ir/article-1-2332-en.html SP - 341 EP - 345 K1 - Medulloblastoma K1 - Extra-axial K1 - Cerebello-pontine (CP) angle K1 - Adult. AB -   Medulloblastoma is quite uncommon in the adult population and even rarer in extra-axial site in cerebello-   pontine (CP) angle. In this report, a 23-year-old male patient with a two month history of deafness, nausea, vomiting and ataxia is presented. Clinical and radiological findings demonstrated a heterogeneously enhanced extra-axial lesion in the right CP angle. Total excision was performed and the histopathological features of medulloblastoma were confirmed. After surgery, the patient had no neurological deficit and the audiometric findings were improved. In addition, he underwent adjuant radiotherapy and no sign of metastatic mass was observed in follow-up spinal cord MRI. Although extremely rare, medulloblastoma must be considered in the differential diagnosis of extra-axial CP angle lesions. LA eng UL http://mjiri.iums.ac.ir/article-1-2332-en.html M3 ER -
