BACKGROUND: Pineal region tumor is a rare and reportable case. Incidence rate adults is 0.025 in 10,000 hence there is no established guidelines among adults  for diagnosis and management of this case.
CASE: A case of a 20-year-old male with a two-month history of  intermittent  headache,  occipital  area  with  VAS  5/10,increasing in severity. Until two days prior to admission with severe headache VAS 9-10/10, occipital, and nonradiating.Patient  noted  episodes  of  projectile  vomiting  hence,admitted. Patient presented with non-lateralizing symptoms but  noted  papilledema  and  parinaud  syndrome.Cranial  MRI with contrast revealed a 2.5cm pineal gland tumor with obstructive  hydrocephalus.  Serum  AFP  (alpha-fetoprotein  )  and  beta-HCG  (beta subunit of human chorionic gonadotropin) were requested and revealed elevated levels.The patient underwent endoscopic third ventriculostomy but no biopsy was done due to high risk of bleeding. Patient underwent series of radiotherapy and was advised to undergo chemotherapy but patient refused. Patient had improved upward gaze but with residuals, no recurrence of headache or vomiting, had normalization of the serum tumor markers but noted increase in size of the tumor despite radiotherapy.
CONCLUSION: Case  reports  of  pineal  region  tumors  will  help doctors  in  the  primary  hospitals  diagnose  such  cases  and differentiate it from benign causes of headache. This will aid in early referral to specialists and early intervention.
