ABSTRACT

Background: Cerebellar hemangioblastoma is a WHO grade one tumor of vascular origin located in posterior cerebral fossa and is the most common primary intra-axial and infratentorial tumor in adults which usually contains a highly vascular mural nodule that shows avid post contrast enhancement on MRI (Magnetic Resonance Imaging). We present a case involving a 41-yearold adult male who came to our hospital with complaints of giddiness. Objective: To differentiate adult posterior fossa tumors from cerebellar hemangioblastoma on MRI. To establish histopathological correlation with imaging finding on MRI. Material and Methods: Magnetic Resonance Imaging (MRI) is the modality of choice for diagnosing cerebellar hemangioblastoma. We used Three Tesla (3T) MRI machine of GE healthcare system for our case study. A microscopic evaluation with haematoxylin and eosin staining sections in low and high magnification was done on histopathology. Subject of our case study is a 41-year-old Adult male patient presented to our institution. Patient was administered Gadolinium contrast agent and was subjected to the MRI scan. Results and conclusions: We diagnosed the patient with Cerebellar hemangioblastoma on MRI and also established a firm Histopathology correlation to strengthen our diagnosis. Thus, excluding other differentials of adult posterior fossa tumors of the brain. Also, post contrast MRI study revealed cyst wall enhancement in our case which is an uncommon finding in cerebellar hemangioblastoma.
