Objective To investigate the clinical,imaging (CT and MRI) and pathological features of intracerebral inflammatory pseudotumour. Methods The clinical, neuroimaging and neuropathological data of a patient with intracerebral inflammatory pseudotumour were analyzed retrospectively. Results The manifestations of this patient included headache, nausea, vomiting, fever and seizures. Brain MRI showed abnormal high T1 and T2 signals in the right frontal lobe and midline shift. The resection pathology showed brain tissue swelling, loss of normal neuron outline, massive inflammatory infiltrations in perivascular spaces. Although the patient was treated with operation, dehydration and antibiotics, he died eventually.Conclusions Intracerebral inflammatory pseudotumour is an unusual disease in clinical practice. This disease is diagnosed mainly depended upon pathological examinations because of no specific clinical and imaging manifestations. The prognosis is not good although operative treatment is performed.
