A patient with nocturnal frontal lobe epilepsy characterized by paroxysmal motor attacks during sleep had brief paroxysmal arousals (PAs), complex episodes of nocturnal paroxysmal dystonia, and epileptic nocturnal wandering since childhood. Ictal SPECT during an episode of PA demonstrated increased blood flow in the right anterior cingulate gyrus and cerebellar cortex with hypoperfusion in the right temporal and frontal associative cortices.
Sarcoidosis is a multisystem disease of unknown origin. Granulomatous bone involvement has an overall incidence of 1-13%. This incidence is probably underestimated in certain patient series because bone involvement is often asymptomatic. The small bones of hands and feet are the most common localizations, while skull, knee, rib, pelvic and sternal localizations are rarely reported. Here we describe some interesting cases of chronic sarcoidosis with unusual bone localizations observed at our regional referral centre for sarcoidosis. We also review the literature to underline the complexity of the disease, the problem of differential diagnosis with respect to malignancies and the need for appropriate and effective therapy of this rare localization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
