Excerpt A dysplasia of the bony walls of the orbit is one of the congenital anomalies associated with generalized neurofibromatosis (1–6). DIFFUSE NEUROFIBROMATOSIS WITH PROPTOSIS. Imaging of the orbit involves detailed evaluation of the globe, bony orbit, the orbital and periorbital soft tissues, and their relationship to each other. Our purpose was to review orbital changes in patients with craniofacial NF1. Some stigmata of NF1 occur in the orbital region. Though these features are frequently emphasized, the psychosocial and emotional morbidities are often overlooked. This is a bone dysplasia allowing the frontal lobe to herniate, not a bone erosion due to en plaque meningioma, neurofibroma or other tumor. 1988 Aug; 151 (2):381–388.

Manifestations of neurofibromatosis in the orbit that have been described include osseous dysplasia of the orbit, orbital neoplasms (optic gliomas, perioptic meningiomas, neurofibro­ mas, and schwannomas), buphthalmos, and plexiform neu­ rofibromas [4]. BACKGROUND AND PURPOSE: The possible relationship of orbit deformities in neurofi- bromatosis type 1 (NF1) to plexiform neurofibromas (PNFs) have not been fully elucidated. Breast cancer is the most common malignancy to metastasize to the orbit, followed by prostate cancer, melanoma, and lung cancer. Br J Ophthalmol. Purpose: The aim of this study was to describe 3 cases of primary orbital schwannomatosis without associated systemic neurofibromatosis. 1-3 Men and women are affected equally. At imaging, gliomas often cause fusiform … Binet was a United States Public Health Service Trainee in Neuroradiology (Grant 0900-4147). To our knowledge, abnormalities of the orbital floor, however, have not been attributed to this disease in the literature until now. Subcutaneous diffuse neurofibroma of the neck: a case report. Neurofibromatosis is a multisystem genetic disorder that is commonly associated with cutaneous, neurologic, ophthalmic, and orthopedic manifestations. Cranio-orbital-temporal neurofibromatosis is an uncommon subtype of NF-1 and is characterized by pulsatile exophthalmos, orbital neurofibromas, sphenoid wing dysplasia, expansion of the temporal fossa, and herniation of the temporal lobe into the orbit. The clinical presentation, imaging features, surgical procedures, and outcomes were defined. The imaging group included five male and five female patients (mean age, 40.6± 19.1 [SD] years; range, 13–69 years) (Table 1).

Neurofibromatosis 1 (NF1) was present in seven patients and neurofibromatosis 2 (NF2) in one patient. … Moore RF. We present a patient with depressive disorder resulting in suicide in a patient with NF1. Axial T1 fat-saturated contrast-enhanced magnetic resonance imaging shows diffuse edema with heterogeneous enhancement of the preseptal soft tissue and superolateral extraconal right orbit consistent with plexiform neurofibroma (short arrow). Other tumor types within this family include neurofibromas and malignant PNSTs, which are more commonly seen in patients with neurofibromatosis (NF). Neurofibromatosis type 1 (NF1) is an autosomal dominant inherited disease. Diffuse neurofibroma of the orbit associated with temporal meningocele and neurofibromatosis-1.

Binet EF, Kieffer SA, Martin SH, Peterson HO. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Orbital Neurofibromatosis Type 1 The National Institute of Health has given the diagnostic criteria for neurofibromatosis type 1(NF1). Enophthalmos of the affected orbit, although rare, has been described as resulting from an overwhelming increase in size of the bony orbit compared to that of the orbital contents (Van der Meulen, 1987; Morax et al., 1988; Jackson and Shaw, 1990). 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. Orbital dysplasia in neurofibromatosis. Friedman JM, Birch PH. In women with bilateral enophthalmos, metastatic scirrhous breast cancer should be considered in the differential diagnosis. Radiology. Orbital manifestations of neurofibromatosis type 1 (NF1) reflects a mix of CNS, musculoskeletal and ocular disease. Neurofibromatosis has been reported to involve the eye and orbit by causing irregularities of the sphenoid and other facial bones and enlargement of the foramina. Neurofibromatosis of lid and orbit in early childhood. 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. 1931 May; 15 (5):272–279. The mean time between imag-ing and pathologic diagnosis was 7.3 months (range, 0–24 months). Methods: This is a retrospective interventional study of 3 patients who presented with multiple, distinct masses in the orbit (n = 3) as well as in the hemiface (n = 1). Magnetic resonance imaging (MRI) of orbit and brain revealed dysplasia of the greater wing of the sphenoid bone of left side with gross thinning and scalloping of outer and inner tables of anterior squamous temporal bone. AJNR 2003; 24 ... Binet EF, Kieffer SA, Martin SH, Peterson HO. NF1 is inherited in an autosomal dominant fashion with variable pathological and clinical expression. CONCLUSION.

Asterion defect : Lucent defects in the calvarium near the lambdoid sutures (refer image above). Cranial MR imaging in neurofibromatosis. David Yousem is currently the Director of Neuroradiology and Professor of Radiology at the Johns Hopkins Hospital. Usually, only one orbit is affected, commonly associated with an ipsilateral extracranial disease. Binet EF, Kieffer SA, Martin SH, Peterson HO. 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 Enlarged skull base foramina due to neurofibromas.

Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Orbital Neurofibromatosis Type 1 Note in this case the innominate line (tangential greater wing of sphenoid) remains intact. Because NF1 is one of the most common genetic disorders, radiologists should be familiar with its imaging manifestations. Orbital dysplasia in neurofibromatosis. Cranial MR imaging in neurofibromatosis. Bognanno JR, Edwards MK, Lee TA, Dunn DW, Roos KL, Klatte EC. Br J Ophthalmol. Orbital schwannomas typically involve the head and neck, and rarely occur within the orbit. Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is the most common of the neurocutaneous syndromes with an incidence of approximately 1 in 2,600 to 1 in 3,500 live births.
