8-YEAR-OLD CHILD WITH A LESION IN THE LEFT NUCLEUS LENTIFORMIS

摘要

An 8-year-oid child presented with symptoms, of raised intracranial pressure starting a few days before clinical presentation. Past medical history was significant for diabetes insipidus centralis, which was diagnosed in February 2001 and treated with Minirin?. Neurological examination was normal.The magnetic resonance imaging scans showed a 25 mm space-occupying lesion with distinct contrast enhancement (Figure 1). The tumor was localized in the left insular region and attached to the nucleus lentiformis and the left thalamic area. The T2 sequence demonstrated significant peritumoral edema with compression of the left ventricle and midline shift (Figure 2). A primary brain neoplasm or an abscess were considered-m the differential diagnoses. A stereotaxic biopsy was performed.
