Gamma Knife Radiosurgery for Recurrent Posterior Fossa Hemangioblastoma

This 47 year old lady, diagnosed case of hemangioblastoma since 2014,underwent excision of posterior fossa SOL & insertion of VP shunt  in 2014 & received cyber knife treatment 7 Gy x 3 fraction in MAY 2015. Now presented with complaints of headache with vomiting & vertigo for 5 months & difficulty in walking for one month.  On clinical examination middle aged lady  has decreased vision & ataxia. MRI brain with contrast dated March 09, 2022 shows abnormal signal intensity enhancing mass lesion  in posterior fossa, involving the cerebellar vermis & shows  progression in disease when compared with previous MRI brain with contrast. Histopathology dated December 16, 2014 shows hemangioblastoma. Risk of GKSRS have been explained. Written and valid consent obtained to proceed. 

                                         PRE-GKSRS                                   POST-GKSRS

Follow-up Comparative Study after One year (February 07, 2023):

Patient visited the gamma knife center for second follow up presented with recent MRI brain with contrast dated  February 07, 2023  shows significant regression in the targeted hemangioblastoma from 27.9cc to 2.8 cc when compared with previous MRI brain with contrast dated March 09, 2022 consistent with good lesion control.
