ABSTRACT
BACKGROUND:
Lack of an olfactory bulb (OB) is typically associated with anosmia.METHODS:
We present a patient with subnormal olfactory function in whom the OB could not be detected with magnetic resonance imaging (MRI).RESULTS:
Olfactory function was evaluated on two occasions. Orthonasal olfactory function was assessed with the "Sniffin' Sticks" test providing a score equivalent to hyposmia. Retronasal olfactory function was studied with "smell powders" indicating a decreased, but not absence of, olfactory function. Importantly, chemosensory event-related potentials were clearly present in response to olfactory and trigeminal stimuli.CONCLUSION:
This indicates that olfactory function may be present in some subjects even when an OB can not be detected with MRI.
