Olfactory hallucinations during migraine in an adolescent with an MRI temporal lobe lesion
1Department of Pediatrics (Neurology) University of Medicine & Dentistry of New Jersey, School of Osteopathic Medicine, Stratford, NJ 08084, USA.
Objective:
To report the first example of an abnormal magnetic resonance imaging (MRI) test in a patient with migraine and olfactory hallucinations and to provide additional evidence for a possible role of the temporal lobe in migraine.
Background:
The relationship between the temporal lobe and migraine with or without hallucinations is unclear and continues to evolve. Clinical and functional neuroimaging studies (positron emission tomography/single photon emission computed tomography) have lent support to the possibility of a relationship. Anatomical neuroimaging with computed tomography has previously been normal.
Methods:
The history and findings of an adolescent with migraine and olfactory hallucinations is reported.
Results:
Brain MRI demonstrated a mass in the temporal lobe.
Conclusions:
Magnetic resonance imaging should be considered in patients with olfactory hallucinations and migraine. In addition, the role of the temporal lobe in migraine warrants further study.
