Psoas abscess localization by gallium scan in aplastic anemia

Area of Science:

• Nuclear Medicine
• Infectious Disease Imaging
• Oncology Supportive Care

Background:

• Gallium 67 scintigraphy is a recognized tool for identifying inflammatory processes.
• Patients with aplastic anemia often experience severe leukopenia and granulocytopenia, increasing infection risk.
• Diagnosing occult infections in immunocompromised patients presents a clinical challenge.

Purpose of the Study:

• To evaluate the utility of Gallium 67 scanning in diagnosing an abscess in a severely granulocytopenic pediatric patient.
• To highlight the role of Gallium 67 scintigraphy in managing complex infections in immunocompromised hosts.

Main Methods:

• A case report of a 10-year-old boy with aplastic anemia and severe granulocytopenia.
• Diagnosis of a psoas abscess was confirmed using Gallium 67 scanning.
• Autopsy findings correlated with imaging results.

Main Results:

• Gallium 67 scanning successfully identified a psoas abscess in a patient with severe granulocytopenia.
• The patient subsequently developed a systemic Candida infection and expired post-bone marrow transplantation.
• Autopsy confirmed a chronic psoas abscess with Candida.

Conclusions:

• Gallium 67 scanning is a clinically effective noninvasive method for evaluating suspected infections in granulocytopenic patients.
• This imaging modality aids in the early detection of deep-seated abscesses.
• Prompt diagnosis through Gallium 67 scans can inform management strategies for immunocompromised patients.
