Sensitivity of radionuclide isotope brain scan in cerebral melioidosis: case report
Abstract:
Melioidosis, an unusual infectious disease formerly confined to the Orient, is being seen with increasing frequency in the United States. We present a report of a patient who had recently traveled in the Far East and subsequently developed pulmonary melioidosis complicated by a fatal encephalitis. Although the radionuclide brain scan was markedly abnormal, computed tomographic studies were minimally abnormal on one occasion and within normal limits on another. The radionuclide brain scan appears to have greater sensitivity in diagnosis of early encephalitis and, therefore, may be the more valuable of the two studies in the diagnosis of this disorder.
Insights
Melioidosis, an infectious disease, is increasingly seen in the US. Radionuclide brain scans show greater sensitivity for diagnosing early encephalitis in patients with this condition compared to CT scans.
Area of Science:
- Infectious Diseases
- Neurology
- Radiology
Background:
- Melioidosis, an infectious disease, is increasingly diagnosed in the United States.
- This case involves pulmonary melioidosis with a fatal encephalitis complication in a patient with recent travel history to the Far East.
Observation:
- A patient presented with pulmonary melioidosis and subsequent encephalitis after traveling to the Far East.
- Diagnostic imaging included radionuclide brain scan and computed tomography (CT).
Findings:
- The radionuclide brain scan showed marked abnormalities, indicating early encephalitis.
- CT scans revealed minimal or normal findings on different occasions, suggesting lower sensitivity for early-stage encephalitis.
Implications:
- Radionuclide brain scans may be more valuable than CT for diagnosing early encephalitis in melioidosis.
- Increased awareness and diagnostic sensitivity are crucial for managing melioidosis cases presenting with neurological complications.
