Objectives:
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.
Methods:
These atypical lesions can pose a diagnostic problem, especially when they are present at disease onset.
Results:
Most MS patients with PLs only have a single episode throughout their disease course, which reflects its low tendency of recurrence.
Conclusions:
We report the rare case of a 34-year-old MS patient who suffered from recurrent pseudotumoral episodes during follow-up.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
