Current approaches to hypothalamic-pituitary radiology.

    Summary

    Computed tomography (CT) is the main imaging tool for pituitary and hypothalamic lesions, though magnetic resonance imaging (MRI) may replace it. CT effectively detects tumors and abnormalities, aiding diagnosis and treatment planning.

    Area of Science:

    • Neurology
    • Radiology
    • Endocrinology

    Background:

    • Computed tomography (CT) is the current primary imaging modality for pituitary and hypothalamic lesions.
    • Magnetic resonance imaging (NMR) is expected to become the preferred method in the future.
    • Pituitary gland size varies, with larger glands in adolescents and women of childbearing age.

    Purpose of the Study:

    • To outline the diagnostic utility of CT in evaluating pituitary and hypothalamic abnormalities.
    • To describe CT protocols for specific clinical presentations.
    • To highlight the role of CT in diagnosing pituitary tumors, cysts, and other pathologies.

    Main Methods:

    • High-resolution, thin-section CT with coronal and sagittal imaging for pituitary tumors and empty sella.
    • Plain and contrast-enhanced CT for visual defects, ocular muscle paralysis, or hypothalamic disturbances.
    • Supplementary angiography and computed cysternography for complex cases.

    Main Results:

    • CT effectively visualizes pituitary and hypothalamic lesions, including microadenomas and cysts.
    • CT aids in differentiating between pituitary tumors and empty sella based on clinical presentation.
    • CT can elucidate various pathologies causing neurological or hormonal disturbances.

    Conclusions:

    • CT remains a crucial tool for diagnosing pituitary and hypothalamic lesions.
    • Specific CT techniques are employed based on clinical presentation for accurate diagnosis.
    • CT plays a vital role in managing patients with pituitary and hypothalamic disorders.
