Unilateral toxic multicystic goiter.

P A Kern, R J Robbins

    Archives of Internal Medicine
    |April 1, 1983
    PubMed
    Summary

    This case study presents a unique instance of toxic multinodular goiter affecting only one lobe of the thyroid. Surgical removal of the affected lobe resulted in normal function of the remaining thyroid tissue.

    Area of Science:

    • Endocrinology
    • Thyroidology
    • Surgical Pathology

    Background:

    • Toxic multinodular goiter (TMG) is a common endocrine disorder characterized by hyperthyroidism due to autonomous nodules within the thyroid gland.
    • Typically, TMG involves diffuse thyroid gland involvement with multiple nodules causing excessive thyroid hormone production.
    • The condition predominantly affects older individuals and is more prevalent in iodine-deficient regions.

    Observation:

    • A 43-year-old woman presented with multiple thyroid cysts and toxic nodules exclusively in the left thyroid lobe.
    • The patient underwent surgical excision of the affected left lobe.
    • Post-operatively, the remaining right thyroid lobe demonstrated normal function without any nodules, cysts, or signs of hyperfunction.

    Findings:

    • This case highlights a rare presentation of toxic multinodular goiter localized to a single thyroid lobe.
    • The successful management via unilateral lobectomy and the subsequent normal function of the contralateral lobe challenge the conventional understanding of TMG as a diffuse process.
    • Histopathological examination confirmed the presence of toxic nodules and cysts in the excised left lobe.

    Implications:

    • This unique case underscores the significant variability in the clinical and pathological manifestations of toxic multinodular goiter.
    • It suggests that localized TMG may occur and can be effectively managed with targeted surgical intervention, preserving contralateral thyroid function.
    • Further research into the specific etiologies and genetic factors contributing to unilateral TMG presentations is warranted to refine diagnostic and therapeutic strategies.
