Imaging Studies II: Positron Emission Tomography and Scintigraphy

91
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Area of Science:

  • Gastroenterology
  • Oncology
  • Radiology

Background:

  • Esophageal schwannoma is an exceptionally rare tumor.
  • Accurate diagnosis is crucial for appropriate patient management.

Purpose of the Study:

  • To describe the typical findings of esophageal schwannoma on FDG PET/CT.
  • To highlight the importance of including esophageal schwannoma in the differential diagnosis of FDG-avid esophageal lesions.

Main Methods:

  • Case report of a patient with esophageal schwannoma.
  • Utilized endoscopic ultrasound to determine tumor location.
  • Performed FDG PET/CT to assess metabolic activity.

Main Results:

  • Endoscopic ultrasound revealed the tumor within the esophageal muscular layer.
  • FDG PET/CT demonstrated intense fluorodeoxyglucose uptake, with a maximum standardized uptake value (SUV max) of 10.
  • The imaging characteristics mimicked malignant neoplasms.

    • Conclusions:

    • Esophageal schwannoma can present as an FDG-avid lesion on PET/CT.
    • Radiologists and clinicians should consider schwannoma in the differential diagnosis of esophageal masses with high FDG uptake.
    • This case underscores the utility of integrated imaging modalities for rare esophageal tumors.
