    A bone scan revealed unexpected radioactivity in one armpit. This was caused by the patient's undershirt becoming contaminated due to localized excessive sweating.

    Area of Science:

    • Nuclear Medicine
    • Diagnostic Imaging
    • Radiology

    Background:

    • Bone scans are crucial for detecting skeletal abnormalities.
    • Unusual findings on bone scans necessitate thorough investigation.

    Observation:

    • An atypical, unilateral axillary concentration of radioactivity was detected during a bone scan.
    • This localized "hot spot" in the axilla was not indicative of a skeletal or metastatic process.

    Findings:

    • The radioactivity was confirmed to be external contamination.
    • The source of contamination was identified as the patient's undershirt.
    • Localized hyperhidrosis (excessive sweating) led to the radioactive tracer adhering to the garment.

    Implications:

    Related Experiment Videos

    • Highlights the importance of considering external contamination in interpreting bone scan results.
    • Underscores the need for careful patient preparation and artifact recognition in nuclear medicine.
    • Demonstrates how physiological conditions like hyperhidrosis can influence imaging outcomes.
