Sir,

A 62-year-old retired instrumentation technician presented with a 5-year long history of progressive left sided hearing loss with recent, rapid aggravation following severe occipital pain and dizziness. He had been operated for symptomatic pheochromocytoma 1½ years back. He recovered satisfactorily with normalization of his blood pressure following excision of the pheochromocytoma.

Neurological examination revealed hyper-reactive deep tendon reflexes in all four limbs, and the pure tone audiogram confirmed left retro-cochlear hearing impairment.

Magnetic resonance imaging and magnetic resonance angiography showed a giant fusiform aneurysm of the vertebrobasilar artery with an uncommon course of the basilar artery resulting in severe brain stem compression on the left side [Figure 1]. These findings were confirmed by cerebral angiography, which clearly delineated the limits of the aneurysmal dilatation extending from the V4 segment of the left vertebral artery right up to the posterior cerebral arteries [Figure 2].{Figure 1}{Figure 2}

Because of its size and the fact that the aneurysm had incorporated the origins of both posterior cerebral arteries, it was neither suitable for direct surgical clipping nor for endovascular coiling. An endovascular procedure using an intraluminal stent to maintain the patency of the vessel, along with strategic coiling of the aneurysmal sac while maintaining the origin of the side branches and important perforators, was proposed, but the patient refused any intervention.

His headache and dizziness regressed after symptomatic medication, and his clinical status remained unchanged at 6 years after the diagnosis of the aneurysm.
