- •Pseudotumoral demyelinating lesions have a minimal diameter greater than 2 cm.
- •Their clinical picture includes atypical neurological symptoms.
- •They represent a diagnostic challenge especially when they appear isolated.
- •Recurrent pseudotumoral episodes are a rare condition in multiple sclerosis.
Multiple sclerosis (MS) is the most common chronic disabling disease of the central nervous system (CNS) in young adults. It is characterized by the presence of multiple demyelinating inflammatory lesions disseminated in the CNS. Pseudotumoral lesions (PL) are rarely observed in patients with MS.
These atypical lesions can pose a diagnostic problem, especially when they are present at disease onset.
Most MS patients with PLs only have a single episode throughout their disease course, which reflects its low tendency of recurrence.
We report the rare case of a 34-year-old MS patient who suffered from recurrent pseudotumoral episodes during follow-up.
