Questions
Findings

How could these episodes be described?

These are mainly complex partial seizures, but some progress to secondary generalisation.

Does anything in the provided history suggest a particular imaging finding?

The history of febrile convulsions can be associated with mesial temporal sclerosis (MTS), with about a third of MTS having had febrile convulsions, but clearly not all children with febrile convulsions will go on to develop MTS. Mesial temporal sclerosis is best seen on a dedicated MRI protocol.

Question 3

What other investigation is important when working up seizure patients?

Show Answer

EEG (electroencephalogram): can help to localise epileptogenic foci, or demonstrate pathognomonic patterns in some patients.

Presentation

Referred from neurology with episodes of a rising sensation and with "out of body" awareness. History of generalized tonic-clonic seizures controlled on phenytoin, last about 2 years ago. Febrile convulsions before the age of 5 years. Recent normal CT head.
