As the alternative name of diffuse astrocytoma implies, the outline of the tumour is not clearly visible in scans, because the borders of the neoplasm tend to send out tiny microscopic fibrillary tentacles that spread into the surrounding brain tissue.

The condition is rare in children older than ten years of age. Most commonly acute cerebellar ataxia affects children between age 18 mo and 7 years. Etiology Acute cerebellar ataxia usually follows 2 3 weeks after an infection, commonly varicella , influenza , Epstein Barr virus , or mycoplasma . The possible mechanism is immune complex deposition in the cerebellum. Clinical features Truncal ataxia with deterioration of gait Slurred speech and pathologic nystagmus nystagmus Afebrile Diagnosis Urgent CT scan is necessary to rule out cerebellar tumor or hemorrhage as cause of the ataxia however in acute cerebellar ataxia, the CT will be normal. Acute cerebellar ataxia is a diagnosis of exclusion. Management Supportive treatment is the only intervention for acute cerebellar ataxia of childhood. Symptoms may last as long as 2 or 3 months.

On 8 February 2005, Henry was diagnosed with a Diffuse Intrinsic Pontine glioma Pontine Glioma , Grade 4, a severe brain tumor that is both inoperable and incurable. He was given weeks to live. After a course of radiotherapy , Henry recovered enough to continue life in a normal fashion. Henry died on 25 December 2005. ref http www.wscountytimes.co.uk district Lights in memory of pupils.1865607.jp ref The fund was started to benefite the SDBTT Brain Tumor Trust , which aims to raise funds and awareness for research into pediatric brain tumors. In late 2008 a major breakthrough in low grade glioma s was made. The researchers, funded by Cancer Research UK and the Henry Barnfield Fund, have pinpointed a rearrangement of DNA that causes around two thirds of all cases of pilocytic astrocytoma the most common brain tumour in five to 19 year olds.
