IntroductionAbduction deficit in the elderly is commonly caused by sixth cranial nerve palsy due to microvasculopathy. However, not all such cases are of neurogenic origin, as our case report shows.Case presentationWe present the case of a 75-year-old woman who was generally unwell, developed acute diplopia and was found to have a right abduction deficit in a quiet eye with no gross orbital signs and symptoms. A computed tomography scan of the head and orbits revealed a metastatic mass in the right lateral rectus muscle. Systemic evaluation confirmed widespread thoracic and abdominal metastases from an occult systemic malignancy. Lateral rectus metastasis from an occult systemic malignancy was masquerading as abducens palsy.ConclusionOrbital metastasis involving extraocular muscles can present as isolated diplopia with minimal local signs and the absence of a history of systemic malignancy. A detailed history and systemic examination can identify suspicious cases, which should be investigated further. The clinician should avoid presuming that such an abduction deficit in the elderly is a benign neurogenic palsy.

Rehabilitation of badly broken endodontically treated teeth is a common problem in restorative dentistry. Tooth with less remaining crown height is indicated for post and core followed by crown to restore normal anatomy, function and esthetics. Patients having reduced interocclusal clearance and are most difficult to manage. Richmond crown is a feasible approach for such cases that can be performed with less incisal clearance as it accommodates post, core and crown thickness. In this case report, diagnosis and treatment planning for a case with fracture of maxillary central incisor along with fabrication technique of Richmond crown has been discussed.
