Answer

The diagnosis of Tolosa-Hunt syndrome is usually one of exclusion.

CBC count, erythrocyte sedimentation rate (ESR), electrolytes with glucose, thyroid function tests, fluorescent treponemal antibody (FTA), antinuclear antibody (ANA), lupus erythematosus (LE) preparation, antineutrophil cytoplasmic antibody (ANCA), serum protein electrophoresis, Lyme titre, angiotensin-converting enzyme (ACE) level, and HIV titre are helpful in eliminating other processes. This level of evaluation is required to exclude other conditions, which can have significant morbidity associated.

Cell count and differential, protein, glucose, fungal and/or bacterial cultures, Gram stain, cytology, and opening pressure of CSF are helpful in eliminating conditions mimicking Tolosa-Hunt syndrome; a mild (lymphocytic) pleocytosis within the spinal fluid may occur in patients with Tolosa-Hunt syndrome.

Anti-GQ1b antibodies may be helpful in distinguishing early, painless Tolosa-Hunt syndrome from Miller Fisher syndrome.
