There is a past history of complete loss of vision in the left eye. No significant family history. No episodes of seizures in the past.

Figure 4:

MRI of the brain revealed a large cystic lesion with pial based intensely enhancing mural nodule in right cerebellar hemisphere causing mass effect over the fourth ventricle (Figures 1, 2 and 3). There is intensely enhancing lesion in posterior chamber of left eye ball (Figure 4).

Gross pathological specimen (A) of the cerebellar lesion showing cystic changes and mural nodule, High power microscopic image (Slide B) shows proliferating vascular capillaries and adjacent vacuolated cell suggestive of hemangioblastomas.

Diagnosis: Von Hippel-Lindau Syndrome

Autosomal dominant multisystem disease caused due to deletion or nonsense mutations of the von Hippel-Lindau tumor suppressor (VHL) gene on chromosome 3p25.3 and is characterized by cerebellar spinal hemangioblastomas, retinal hemangioma, pancreatic and renal Cysts, renal clear cell carcinomas, pheochromocytomas, and islet cell tumors of the pancreas.

Surgical excision of lesions is the possible mainstay of therapy. Photocoagulation and cryotherapy of retinal lesions.
