Gerstmann Syndrome; A Frequent Pathology Presenting With A Rare Symptomatology

We report a case of glioblastoma multiforme (GBM) of the left parietal lobe presenting with Gerstmann Syndrome (GS). A 54-year-old woman presented dyscalculia. The computed tomography depicted a cystic mass in the left parietal lobe, thus she was referred to our department. Her detailed neurological examination revealed left-right disorientation, finger agnosia and agraphia with dyscalculia. Pathological examination of the tumor revealed GBM. This most common primary malignancy of the central nerve system rarely presents with GS. Detailed neurological examination may locate the pathology of the brain prior to the radiological examinations and is still precious despite the rapid progression of the radiological technologies.
