    Primary angiitis of the central nervous system (PACNS) is a rare vasculitis restricted to the central nervous system without systemic involvement. Delay in diagnosis and treatment is common due to its non-specific symptoms and lack of non-invasive diagnostic tests. Myelopathy can occur in PACNS, during the clinical course of the illness, with or without cerebral symptoms. We describe here a 51 year-old ethnic Chinese woman who presented initially with paraparesis without cerebral symptoms. The diagnosis of PACNS was eventually made from brain biopsy when she subsequently developed cerebral involvement. Despite aggressive treatment, the patient developed progressive neurological deterioration and died. This patient demonstrates the rare occurrence of myelopathy as the sole initial presentation of PACNS.

    PURPOSE: We aimed to analyze our 4-year experience of intra-arterial chemotherapy (IAC) for retinoblastoma (RB) and to examine the tumor response, globe salvage, mortality, and safety profile of IAC in the Malaysian profile.

    MATERIALS AND METHODS: This was a retrospective, interventional case series. A total of 22 eyes of 20 patients with RB who underwent IAC using melphalan and topotecan from January 2018 to December 2021 in Hospital Kuala Lumpur were retrospectively reviewed. Tumor response, globe salvage, mortality, and safety profile of IAC were compared based on the International Classification of Retinoblastoma.

    RESULTS: The mean patient age at IAC was 21.3 months. An overall globe salvage rate of 63.6% was observed: more specifically, 100% for Group A, 75% for Groups B and C, 66.7% for Group D, and 42.9% for Group E. Poor tumor response after IAC was significantly associated with a lesser chance of globe salvage (P = 0.045). The overall rate of good tumor response following IAC was 77.3%. Specifically, rates of good tumor response in each group were 100%, 75%, 75%, 83.3% and 71.4% in group A, B, C, D and E, respectively. The mortality rate was 5%. Complications (per-catheterization) included cerebral infarct (2.2%), oxygen desaturation (2.2%), vomiting (26.1%), periorbital edema (8.8%), ptosis (6.5%), fever, femoral hematoma, and hyperpigmentation over lid (4.4% each).

    CONCLUSION: Four-year experience showed that IAC is a safe and effective method for RB management. Patients with a poor response after IAC may have a lower chance of globe salvage. Careful patient selection is of utmost importance to achieve the best outcome in a setting of limited health-care resources.
