Painful ophthalmoplegia syndrome, beyond Tolosa-Hunt syndrome. A case series.

Painful ophthalmoplejía syndrome is characterised by the presence of peri-orbital or peri-cranial pain that is accompanied by paralysis of the oculomotor nerves. The differential diagnosis is broad, and requires a rigorous study. Three clinical cases of patients with painful ophthalmoplejía syndrome are described, in which multiple extension studies were required to obtain an aetiological diagnosis. Painful ophthalmoplejía syndrome is a complex disorder that has multiple causes, including infections, inflammatory, and tumour processes. Biopsy should be considered in those cases in which non-invasive studies are inconclusive.
