Lesions of the Hypothalamus: MR Imaging Diagnostic Features

摘要: The hypothalamus is susceptible to involvement by a variety of processes, including developmental abnormalities, primary tumors the central nervous system (CNS), vascular tumors, systemic affecting CNS, and inflammatory granulomatous diseases. may also be involved lesions arising from surrounding structures such as pituitary gland. Magnetic resonance (MR) imaging modality choice for evaluating anatomy pathologic conditions hypothalamus. MR differential diagnosis depends on accurate anatomic localization tissue characterization hypothalamic through recognition their signal intensity contrast material enhancement patterns. Diffusion-weighted proton spectroscopy can helpful in differentiating among various types lesions. Key features, addition patient's age clinical findings at presentation, developing involving region.
