Summary
Multiple complete ring-shaped enhancing lesions on MRI are a rare finding in acute disseminated encephalomyelitis (ADEM). This case report highlights this unusual presentation of ADEM in a 36-year-old female patient.
Area of Science:
- Neurology
- Radiology
- Immunology
Background:
- Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease.
- ADEM lesions typically show variable contrast enhancement patterns on MRI.
- Complete ring-shaped enhancement is an uncommon finding in ADEM.
Observation:
- Enhancing lesions in ADEM typically present with various patterns like nodular, amorphous, or incomplete ring-like configurations.
- Multiple, complete ring-shaped enhancing lesions on contrast T1WI are an uncommon observation in ADEM.
Findings:
- This report details a rare MRI finding of multiple, complete ring-shaped enhanced lesions in a 36-year-old female patient diagnosed with ADEM.
- The observed enhancement pattern deviates from the typical presentations described in the literature for ADEM.
Implications:
- Recognizing this rare MRI finding can aid in the differential diagnosis of demyelinating diseases.
- Further research may explore the specific pathophysiological mechanisms underlying such rare enhancement patterns in ADEM.
