[Nuclear magnetic resonance tomography in the differential diagnosis of adrenal gland hemorrhage and neuroblastoma in a newborn infant].

Adrenal hemorrhages in newborns are usually diagnosed by sonography. Magnetic resonance imaging is indicated when morphological change, clinical appearance and follow-up do not allow differentiation of adrenal hemorrhage and neuroblastoma. Using artefact-suppressing sequences, the adrenal gland can be examined with modern MRI systems. The adrenal gland hemorrhage is characterized by a typical signal behaviour. If a haematoma persists over a longer period, a circular methemoglobin zone can be observed. An additional contrast application (Gadolinium-DTPA) can aid in demonstrating vascular tumors.
