Visual field deficit: a rare initial symptom of autoimmune pancreatitis

Cerebral involvement in IgG4-related disease

IgG4-related disease is a recently recognised multi-system disease. Common organ involvement includes the pancreas, biliary tree and salivary glands. Central nervous system involvement has been infrequently reported. In a single-centre cohort of 84 patients, we report cerebral involvement in three (4%) patients. Details of cerebral involvement in these patients are outlined, including pituitary involvement in two patients and a diffuse autoimmune-like encephalopathy in the other.

Immunoglobulin G4-positive Sclerosing Idiopathic Orbital Inflammation: New Neuro-ophthalmological Presentations

We report two rare cases of biopsy proven Immunoglobulin G4-related sclerosing orbital inflammation (IgG4SOI). The first case had intracranial involvement which, to our knowledge, is the first IgG4SOI case with serum cerebrospinal fluid abnormalities and the second case had an unusual presentation of a compressive optic neuropathy and systemic lymphadenopathy.
