Parosmia is a qualitative smell disorder of unclear etiology characterized by distorted smell sensations triggered by an odor. Posttraumatic and postviral olfactory loss are considered to be the main causes of parosmia, while a number of other neuropsychiatric or drug induced conditions have been described as rare etiological factors. Parosmia is consistently associated with various degrees of quality of life impairment, with food intake or psychiatric disorders described in severe cases. We hereby present a case of a 32 years old woman with severe parosmia apparently associated with a neurovascular compression syndrome involving the olfactory nerve and olfactory bulb and discuss the treatment options. We suggest that, similar to trigeminal neuralgia, vascular compression syndromes could represent a cause in cases of parosmia with unclear etiology. Attention should be focused on correctly diagnosing and finding appropriate treatment solutions in these cases.
