Degenerative changes in hypophyseal adenomas: CT features.

M Rosa, S Schiavoni, T Arcuri

    Italian Journal of Neurological Sciences
    |September 1, 1983
    PubMed
    Summary

    Computed tomography (CT) effectively identified degenerative changes like necrosis, cysts, bleeding, and calcification in 16 hypophyseal adenoma patients. This imaging aids in differential diagnosis and treatment planning for these pituitary tumors.

    Area of Science:

    • Neuroradiology
    • Endocrinology
    • Pathology

    Background:

    • Hypophyseal adenomas are common pituitary tumors.
    • Degenerative changes within adenomas can complicate diagnosis and treatment.
    • Accurate identification of these changes is crucial for patient management.

    Purpose of the Study:

    • To evaluate the utility of computed tomography (CT) in detecting degenerative changes in hypophyseal adenomas.
    • To assess the role of CT density values in the differential diagnosis of these pituitary lesions.
    • To determine if CT findings can aid in treatment planning for patients with hypophyseal adenomas.

    Main Methods:

    • CT scans were performed on 16 patients with hypophyseal adenomas.
    • Density values of degenerative changes (necrotic-cystic, bleeding, calcification) were analyzed.

  • Histopathological examination and surgical findings served as verification methods.

    • Main Results:

    • CT successfully visualized necrotic-cystic changes, bleeding, and calcification in hypophyseal adenomas.
    • Analysis of CT density values provided useful diagnostic information.
    • The imaging findings correlated well with operative and histological results.

    Conclusions:

    • CT is a valuable tool for identifying degenerative changes in hypophyseal adenomas.
    • CT-based evaluation of these features aids significantly in differential diagnosis.
    • This imaging modality assists in planning appropriate treatment strategies for pituitary adenomas.
