Lobulated / Lobulation

    • What is it:
      • “Lobulated” refers to a structure or mass that is divided into rounded or lobe-like sections, often giving it a “lobed” appearance. Lobulation refers to the process or condition of being lobulated, where a shape or object is formed by or has distinct lobes.
    • Etymology:
      • The term “lobulated” is derived from “lobus” (Latin for lobe), which refers to a rounded or segmented part. “Lobulation” comes from “lobus” as well, indicating the state of being divided into lobes.
    • AKA:
      • Lobulated mass: Often used in imaging to describe masses or lesions that appear divided into lobes or rounded sections.
      • Multilobular: A synonym often used to describe structures that have multiple lobes.
    • TCV adjectives it applies to:
      • Shape: Lobulated describes the physical shape of a mass, organ, or structure that exhibits a lobed or segmented form.
      • Character: It refers to the characteristic appearance of an object or structure that appears subdivided into lobes.
    • Modality:
      • Lobulated shapes are commonly observed in CT scans, MRI, and ultrasound, particularly when identifying masses, tumors, or organs with segmented structures.
    • What does it imply:
      • Normal: Lobulation can be a normal anatomical feature, such as in organs like the liver, lungs, or kidneys.
      • Abnormal: A lobulated shape may indicate pathology, such as:
        • Neoplasms: Benign or malignant tumors can have a lobulated appearance.
        • Cysts or abscesses: Certain cystic lesions may appear lobulated.
        • Fibrosis: Can lead to lobulated patterns in the affected tissues, such as in the lungs or liver.
    • Next step:
      • Imaging evaluation:
        • Further evaluation with CT or MRI can help differentiate between benign and malignant lobulated masses.
        • Biopsy may be required to determine the exact nature of a lobulated mass, especially when malignancy is suspected.
