The symptoms of a PICA aneurysm may clinically mimic cervical myeloradiculopathy, and that PICA aneurysms may thus be overlooked ¹⁾.

Posterior inferior cerebellar artery aneurysm treatment.

The largest review of PICA aneurysms has been conducted by Peerless and Drake ²⁾ who reviewed 146 cases of PICA aneurysms and classified outcomes as excellent, good, poor, and dead, without any objectivity in their outcomes.

These aneurysms have a high re-bleeding rate (78%) and dissecting nature. In the series of Deora et al. too, IVH rates were 80%, while no re-bleeding was encountered. This may be due to the policy to operate within 24 hours of patients’ arrival and early referral of patients ³⁾.

These aneurysms present with poor initial neurological status. This is because of the location of this aneurysm. Over 83% of these cases present with IVH as the blood enters from the foramen of Luschka or foramen of Magendie and tracks intraventricularly ⁴⁾.
