MRI and Proton Spectroscopy in Lowe Syndrome

The oculocerebrorenal syndrome of Lowe (OCRL) is an X-linked disorder characterized by major abnormalities of eyes, nervous system, and kidneys. We report two patients with typical intracranial lesions on MRI. The proton spectroscopy study of the periventricular white matter showed a moderate elevation of the signal at 3.56 ppm in the patient with cystic lesions. This resonance is usually assigned to myo-inositol and interpreted as a glial marker. In our patient it could also represent a true accumulation inside the cysts of phosphatidylinositol 4,5-biphosphate which is not degraded in patients with Lowe syndrome.

Key words

Lowe syndrome - Oculocerebrorenal syndrome - OCRL - MRI - MRS - Magnetic resonance spectroscopy - Phosphatidylinositol 4,5 biphosphate - Myo-inositol - White matter disease - Metabolic disease
