The coexistence of fibrous dysplasia and aneurysmal bone cyst in the craniofacial region is extremely rare. This article presents a unique case involving the skull base, diagnosed using computed tomography and magnetic resonance. Imaging revealed a characteristic expansile mass with a ground-glass appearance alongside cystic areas exhibiting fluid-fluid levels, indicative of fibrous dysplasia and aneurysmal bone cyst.

Introduction: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that affects multiple systems and organs, including the central and peripheral nervous systems. Papilledema and idiopathic intracranial hypertension, in the absence of space-occupying lesions or other detectable causes, is a rare manifestation. We report the case of a young woman with chronic headache, papilledema, and intracranial hypertension on examination, in whom a de novo diagnosis of systemic lupus erythematosus and class V lupus nephritis was made.

To maintain internal ion balance in marine environments, teleost fishes leverage seawater (SW)-type ionocytes to actively secrete Na and Cl into the environment. It is well established that SW-type ionocytes use apically expressed cystic fibrosis transmembrane conductance regulator 1 (Cftr1) as a conduit for Cl to exit the gill. Here, we investigated whether the Ca-activated Cl channel, anoctamin 1 (Ano1), provides an additional path for Cl-secretion in euryhaline mummichogs ().
