The occurrence of cavernous sinus involvement in neurosarcoidosis is rare, which can complicate the diagnostic process. We present a case of neurosarcoidosis demonstrating progressively deteriorating right cavernous sinus syndrome in a woman in her 50s, affecting the oculomotor, abducens and the ophthalmic division of the trigeminal nerves. MRI demonstrated meningeal thickening along the lateral wall of the right cavernous sinus, and a pan-CT scan of the chest, abdomen and pelvis revealed disseminated sarcoidosis involving the lungs and the liver. Histopathological analysis of the liver lesion ultimately confirmed the diagnosis of sarcoidosis. This case underscores the significance of considering neurosarcoidosis as a potential cause of cavernous sinus syndrome. In such cases, early initiation of corticosteroid treatment, with or without steroid-sparing agents, is crucial to prevent disease progression and relapse.<\/jats:p>","DOI":"10.1136\/bcr-2024-259714","type":"journal-article","created":{"date-parts":[[2024,7,16]],"date-time":"2024-07-16T22:00:14Z","timestamp":1721167214000},"page":"e259714","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Neurosarcoidosis
