A 29 year old male presented with headache and no neurological signs. MRI brain strongly suggested an aggressive primary brain tumour in the right frontal lobe but histopathology revealed a pleomorphic lymphoid infiltrate, necrosis and vague granulomata and vasculitis was diagnosed. There was aggressive clinico-radiological progression despite two debunking surgeries, corticosteroids and cyclophosphamide.On review the following were noted: areas of necrosis and focal diffuse lymphoid infiltrate showing perivascular cuffing; the presence of granuloma formation and vascular necrosis was less certain; overwhelming predominance of T-cells within the parenchyma; high T-cell mitotic activity and the mild nuclear atypia of the T-cells. PCR demonstrated no clonal immunoglobulin gene but showed a T-cell receptor gene rearrangements.The diagnosis was revised to primary T-cell CNS Lymphoma. Arabinoside & methotrexate were administered.Cerebral vasculitis may present with the imaging appearances of a malignancy. In the current case, a mass lesion was misdiagnosed as vasculitis due to atypical histopathology.

Our Neurology unit is in a busy district general hospital; serving a deprived inner London community, providing a ward consultation service 5 days a week. The unit consists of 5 consultant Neurologists, a consultant Neuroradiologist and 2 specialist nurses. In 2016, a junior doctor was appointed. By analysing data from 10 months in 2015 and 2017; we assessed the impact on the delivery of Neurological care, before and after the appointment. The unit saw a 157% increase in number of patients seen, including a significant proportion now seen in ED and ambulatory care. This is equivalent to a minimum of 2 more patients each working day (n=872 vs. 1317). The percentage of patients seen on same day of referral (<12 hours) increased from 47% to 77%. The proportion of inpatients reviewed who were then followed up on the ward during their stay, increased from 13.9% to 35.5%, representing increased availability of continuing Neurology advice. The percentage of patients who waited more than 24 hours for Neurology input decreased from 14.9% to 5.83%. Our results support the appointment of a full time junior colleague to allow rapid, safe and ongoing Neurological input to patients and to support ED and admitting colleagues.
