Summary
Herpes simplex encephalitis typically shows low-density lesions on CT scans. This study reports rare cases of hemorrhagic lesions, offering insights into atypical computed tomography findings for this neurological disorder.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Herpes simplex encephalitis (HSE) is a severe neurological condition.
- CT scans commonly reveal low-density temporal lobe lesions in HSE.
- Hemorrhagic lesions are infrequently seen on CT in HSE, contrasting with pathology findings.
Observation:
- This report details two unique cases of HSE presenting with hemorrhagic lesions on CT.
- These cases highlight the variability in CT manifestations of HSE.
Findings:
- Atypical CT findings, specifically hemorrhagic lesions, can occur in herpes simplex encephalitis.
- The presence of hemorrhage on CT may not exclude HSE.
Implications:
- Recognizing these atypical CT findings is crucial for timely diagnosis and treatment of HSE.
- This expands the understanding of neuroimaging in HSE, aiding differential diagnosis.
