Transient lesion of the splenium

Case contributed by Dr Ali Nourian


Acute onset vertigo and severe weakness.

Patient Data

Age: 20 years
Gender: Male

Normal brain CT 

Well circumscribed, small oval lesion in the midline within the substance of the splenium of corpus callosum which is  hyperintense on T2WI and FLAIR, isointense on T1WI1

Normal follow up brain MRI 10 days later without any treatment and the patient was symptom-free.

Case Discussion

The small midline splenial lesion disappeared on the follow-up MRI, thus proving to be a transient lesion of the splenium.

As the patient had viral upper respiratory infection and fever about one week earlier, viral etiology is the most probable cause of symptoms in this case.
