Computed tomography of systemic lupus erythematosus

Area of Science:

• Neurology
• Radiology
• Immunology

Background:

• Systemic lupus erythematosus (SLE) is a complex autoimmune disease with potential neurological manifestations.
• Cerebral involvement in SLE can lead to significant patient morbidity and mortality.
• Accurate diagnostic tools are crucial for managing neurological complications in SLE.

Purpose of the Study:

• To correlate computed tomographic (CT) findings with clinical symptomatology in patients with systemic lupus erythematosus (SLE).
• To identify the major neuroimaging abnormalities associated with SLE.
• To discuss the underlying neuropathology of observed CT changes.

Main Methods:

• Retrospective analysis of CT scans from 14 patients diagnosed with SLE.
• Correlation of radiological findings with detailed clinical presentations and symptomatology.
• Review of neuropathological data related to the identified CT abnormalities.

Main Results:

• Computed tomography (CT) demonstrated significant abnormalities in the brains of SLE patients.
• Major findings included microinfarctions (evidenced by perivascular atrophy), large infarcts, and intracranial hematomas.
• These neuroimaging findings were correlated with the patients' clinical symptoms.

Conclusions:

• CT is a valuable tool for detecting major central nervous system abnormalities in SLE.
• The identified CT findings, including infarcts and hematomas, are significant indicators of neurological compromise in SLE.
• Understanding these radiological patterns aids in the clinical management and neuropathological interpretation of SLE-related brain changes.
