  • This is a retrospective study of twenty-two patients (including 4 recurrent cases) with meningioma en-plaque, presenting with hyperostosis and proptosis. (springeropen.com)
  • Proper drilling of the lateral and superior orbital walls with excision of any intra-orbital soft tissue components is all key points for better surgical resection and clinical regression of proptosis. (springeropen.com)
  • The main presenting symptoms are proptosis, visual impairment, and not uncommonly retro-orbital pain. (springeropen.com)
  • We retrospectively studied and evaluated twenty-two patients with spheno-orbital meningiomas presenting with proptosis who underwent surgical resection. (springeropen.com)
  • Localized pain in or behind the eye or orbit may suggest intra-orbital pathology and headache may suggest intracranial pathology. (eyewiki.org)
  • However, factors such as extension of the hyperostosis to the infra-temporal fossa or medial orbital wall, tumor invasion of the cavernous sinus, or adherence of tumor to the orbital muscles, prevent total excision. (springeropen.com)
  • A brain tumor is an intracranial solid neoplasm, a tumor within the brain or the central spinal canal.Brain tumors include all tumors inside the cranium or in the central spinal canal. (absoluteastronomy.com)
  • It is a benign, nongranulomatous orbital inflammatory process characterized by extraocular orbital and adnexal inflammation with no known local or systemic cause. (wikipedia.org)
  • Its diagnosis is of exclusion once neoplasm, primary infection and systemic disorders have been ruled out. (wikipedia.org)
  • Ptosis and diplopia from ophthalmoplegia with an ipsilateral mydriatic pupil may suggest a third nerve palsy versus an ipsilateral miotic pupil and mild ptosis which may suggest a concomitant Horner syndrome. (eyewiki.org)
  • However, if there is muscle restriction (e.g., thyroid eye disease, orbital fracture, orbital myositis) then the diplopia may be worse in the opposite field of action of the restricted muscle. (eyewiki.org)
  • Spheno-orbital meningiomas (SOM) represent a subgroup of sphenoid ridge meningiomas that are also known as the en-plaque meningiomas account for 20% of intracranial meningiomas [ 1 ]. (springeropen.com)
  • They include inflammation of the extraocular muscles (myositis) with tendinous involvement, orbital fat stranding, lacrimal gland inflammation and enlargement (dacryoadenitis), involvement of the optic sheath complex, uvea, and sclera, a focal intraorbital mass or even diffuse orbital involvement. (wikipedia.org)
  • Rare cases of precursor B-LL involving orbital mass and plasmablastic lymphoma involving paranasal sinuses were studied. (ijmpo.org)
  • nonetheless, biopsy may be needed to exclude neoplasm or if symptoms are progressing, atypical, or recurrent. (medscape.com)
  • Spheno-orbital meningiomas are characterized by bone invasion with extensive hyperostosis and possible encroachment into the orbit, infra-temporal fossa, and/or the cavernous sinus that render total surgical excision challenging. (springeropen.com)
  • Spheno-orbital meningiomas are diagnosed by their pattern of growth, based on radiographic appearance and not on the basis of their histological morphology [ 7 ]. (springeropen.com)
  • In the authors' experience, thin-slice high-magnetic field MRI of the cavernous sinus region, including coronal sections with and without contrast and fat-suppressed cuts of the orbital regions, is the modality of choice. (medscape.com)
  • A differential diagnosis includes lymphoproliferative lesions, thyroid ophthalmopathy, IgG4-related ophthalmic disease, sarcoidosis, granulomatosis with polyangiitis, orbital cellulitis and carotid-cavernous fistula. (wikipedia.org)
  • Appropriate use of ancillary studies is important to support the diagnosis of RDD while excluding other histiocytic neoplasms and reactive histiocytic proliferations. (bvsalud.org)
  • Magnetic resonance imaging and computed tomography revealed a mass extending from the right cavernous sinus to the orbital fissure with neighboring bone lysis. (e-jvc.org)
  • It may occur as a complication of spreading infection from the ethmoid, sphenoid, or frontal sinuses or from midfacial, dental, or orbital infections. (medscape.com)
  • In the setting of extensive sclerosis there may be restriction, compression, and destruction of orbital tissue. (wikipedia.org)
  • Idiopathic orbital inflammation has a varied clinical presentation depending on the involved tissue. (wikipedia.org)
  • It can range from a diffuse inflammatory process to a more localized inflammation of muscle, lacrimal gland or orbital fat. (wikipedia.org)
  • Pediatric IOI accounts for about 17% of cases idiopathic orbital inflammation. (wikipedia.org)
  • proposes that organisms resembling Mollicutes cause orbital inflammation by destroying the cytoplasmic organelles of parasitized cells. (wikipedia.org)
  • The histopathology of idiopathic orbital inflammation is described as nondiagnostic and diverse. (wikipedia.org)
  • Inflammatory changes in the cavernous sinus, superior orbital fissure, and/or orbital apex are typically observed on high-resolution contrast-enhanced imaging. (medscape.com)
  • The most often reported are: intra- and extracavernous or metastatic neoplasms, intra-cavernous carotid artery aneurysms, carotid-cavernous fistulas (see image below), infections, thrombosis, and Tolosa-Hunt syndrome. (medscape.com)
