Orbital manifestations of neurofibromatosis type 1 (NF1) reflects a mix of CNS, musculoskeletal and ocular disease. David Yousem is currently the Director of Neuroradiology and Professor of Radiology at the Johns Hopkins Hospital. Neurofibromatous involvement of the orbit and visual apparatus produces a distinctive (but not specific) radiological pattern which may include a congenital defect of the sphenoid bone, overgrowth of the bony orbit, a bulging temporal fossa, an enlarged optic canal and an abnormal pituitary fossa. Neurofibromatous involvement of the orbit and visual apparatus produces a distinctive (but not specific) radiological pattern which may include a congenital defect of the sphenoid bone, overgrowth of the bony orbit, a bulging temporal fossa, an enlarged optic canal and an abnormal pituitary fossa. Neurofibromatosis is a multisystem genetic disorder that is commonly associated with cutaneous, neurologic, ophthalmic, and orthopedic manifestations. AJR Am J Roentgenol.

Neoplasms that arise from the optic nerve or its sheath include glioma and meningioma. Neurofibromatosis type 1 (NF1) is an autosomal dominant inherited disease. Moore RF. AJR Am J Roentgenol. Two patients with orbital neurofibromatosis associated with enophthalmos are presented here with their 3D-CT imaging (Fukuta et al., 1990). Mortada A. Fifty cases of neurofibromatosis of lid and orbit that were followed up from early childhood for about 20 years showed: 1. Imaging preceded Some stigmata of NF1 occur in the orbital region. Because NF1 is one of the most common genetic disorders, radiologists should be familiar with its imaging manifestations. Radiology. Cranial MR imaging in neurofibromatosis. Sphenoid wing dysplasia—hypoplastic/absent greater wing ± lesser wing giving rise to ‘bare orbit’ sign on plain film). 1969 Oct; 93 (4):829–833. Our purpose was to review orbital changes in patients with craniofacial NF1. At imaging, gliomas often cause fusiform … NF1 is inherited in an autosomal dominant fashion with variable pathological and clinical expression. 1-3 Men and women are affected equally. The clinical presentation, imaging features, surgical procedures, and outcomes were defined. One such rare case of cranio-orbital-temporal neurofibromatosis with hemimegalencephaly is reported here. Radiology. Purpose: The aim of this study was to describe 3 cases of primary orbital schwannomatosis without associated systemic neurofibromatosis. Neurofibromatoses (NF) comprise a number of clinically and genetically distinct inherited conditions that carry a high risk of tumor formation.They fall under the wider classification of phakomatoses.The tumors particularly involve the central and peripheral nervous systems: neurofibromatosis type 1 Cranial MR imaging in neurofibromatosis. We present a patient with depressive disorder resulting in suicide in a patient with NF1. 1931 May; 15 (5):272–279. To our knowledge, abnormalities of the orbital floor, however, have not been attributed to this disease in the literature until now. The patient has manifestations of neurofibromatosis type 1 as evident by sphenoid wing dysplasia (bare orbit sign) as well as plexiform neurofibromata involving the preseptal, septal and postseptal regions of the right orbit.
