Abstract:
A patient with tumefactive multiple sclerosis (MS) initially presented at the age of 87 years; the revised diagnostic criteria from the International Panel on MS (2001) were fulfilled. Late-onset MS and tumefactive demyelinating lesions are discussed. This case suggests that MS can occur at any age. MS should be borne in mind for differential diagnosis if a brain tumor-like lesion with little mass effect and edema is found in an elderly patient.
Insights
Late-onset multiple sclerosis (MS) can occur in elderly patients, even presenting at 87 years old. Tumefactive MS lesions mimic brain tumors, highlighting the need for broad differential diagnoses in older adults.
Area of Science:
- Neurology
- Neuroimmunology
- Demyelinating Diseases
Background:
- Multiple Sclerosis (MS) is typically diagnosed in younger adults.
- Tumefactive demyelinating lesions are rare, large MS lesions.
- Late-onset MS (LOMS) presents diagnostic challenges.
Observation:
- An 87-year-old patient presented with symptoms fulfilling revised International Panel on MS (2001) criteria.
- The patient exhibited a tumefactive demyelinating lesion.
- The lesion showed minimal mass effect and edema, resembling a brain tumor.
Findings:
- This case demonstrates that multiple sclerosis can manifest at any age.
- Late-onset MS is a viable diagnosis in the elderly population.
- Tumefactive lesions in elderly patients warrant consideration for MS.
Implications:
- MS diagnosis should not be limited by age, even in octogenarians.
- Tumefactive lesions in the elderly require careful differential diagnosis, including MS.
- Increased awareness of LOMS can improve timely diagnosis and management.
