BACKGROUND:  Arteriovenous malformations (AVMs) of the scalp are rare and infrequently encountered by the neurosurgeon. CASE DESCRIPTION:  We report a unique case of a 42-year-old patient who presented with a progressive worsening of visual acuity in the right eye (lower quadrantanopia) and palpebral ptosis. Physical examination revealed a right exophthalmos and a right frontoparietal scalp soft swelling when the patient was in the supine position. Neurologic work-up showed a scalp AVM extending into the orbit and connected to an intraorbital cavernous angioma...

INTRODUCTION: Thyroid eye disease (TED), is a term referring to the extrathyroidal manifestation of Grave's disease, a disorder which is currently the most common cause of hyperthyroidism and is characterised by underlying autoimmunity.The pathogenic course of the disease can be broadly classified into two stages, an early inflammatory and a late fibrotic stage. These stages are reflected in clinical severity and activity classifications, such as Clinical Activity Score and Class 0: No signs or symptoms, 1: Only signs, no symptoms (e...

We present a case of a 36-year-old man who developed rapid onset of proptosis and orbital compartment syndrome resulting in no light perception vision. He was treated with surgery and subsequent rituximab therapy with some recovery of vision and motility. Though the range of presentations of idiopathic orbital inflammation is broad, such rapid evolution of proptosis with complete vision loss is very uncommon.

BACKGROUND: In transsphenoidal endoscopic cranial base surgery, a precise navigational support may be crucial. This is particularly evident in case of tumors extending to the parasellar region or in recurrent tumors whereas the normal anatomy has been altered by previous surgery/radiotherapy. METHODS: Previous unsatisfactory experiences with a variety of navigation techniques in this type of surgery, encouraged us to perform an endoscopic endonasal approach with an OArm® (Medtronic, Inc...

BACKGROUND: Malignant melanoma predominantly occurs in whites, and is potentially fatal. Distant metastases often occur in lung, liver, brain, and could occur without prior regional disease. Conjunctival melanoma metastasis to contralateral orbit has never been reported. PATIENT PRESENTATION: A 60-year-old man who underwent a left primary conjunctival neoplasm resection 11 months ago presented for the evaluation of a conjunctival dark-colored mass with a bulging left lower eyelid that directly invaded the orbits bilaterally...

BACKGROUND: Wide surgical access to the orbital floor and medial wall is often impaired by the course of the inferior oblique muscle. There is no current consensus on the optimal surgical approach for exposure, and techniques involving inferior oblique division are generally shunned for concern of possible complications. OBJECTIVE: To determine the safety and outcomes of inferior oblique division and reattachment for surgical access to the orbital floor and medial wall during orbital fracture repair...

PURPOSE: To test the hypothesis that the orbit expands in the cranial vault after wide dural exposure after minimally invasive extradural transorbital decompression for thyroid eye disease. METHODS: A cross-sectional cohort study of 36 patients (60 orbits). Preoperative and postoperative (6 months) orbital CT following extradural transorbital decompression was analyzed. Primary outcome measure was the percentage area of the cranial vault occupied by orbital and brain tissue in a predefined window before and after surgery...

Several surgical options are available for treating the different types of craniosynostosis, including fronto-orbital advancement and remodeling, total or subtotal cranial vault remodeling, barrel stave osteotomy with cranial remodeling, endoscopic suturectomy, monobloc advancement and cranioplasty, and revision cranioplasty. High-resolution, low-dose CT with 3D reconstructed images and volumetric analysis can be useful for evaluating the craniofacial skeleton following surgery. The various types of craniosynostosis surgery and corresponding imaging findings are reviewed in this article...

Sinonasal organized hematoma, which has locally aggressive characteristics, is a non-neoplastic disease. We report a rare case of sphenoid sinus organized hematoma causing acute visual loss. A 35-year-old male presented with progressive headaches, retro-orbital pain, and frequent epistaxis. He had a medical history of aplastic anemia and of taking warfarin for a valvular heart disease. On image studies, an expansive soft tissue density lesion with bony destruction was found in his left sphenoid sinus. While waiting for elective surgery, acute visual loss occurred...

Schwannoma (neurilemmoma) is a benign tumour that arises from the Schwann cells which cover the nerve sheaths of the peripheral or autonomic nervous system especially the sympathetic system. Reported cases of schwannoma arising from the sinonasal tract are rare. We report a case of a 28-year-old man who presented to otolaryngology-head and neck surgery clinic with left cheek swelling and left-sided nasal obstruction for 1-year period. Endoscopic examination and high-resolution CT scan revealed a homogenous expansile mass occupying the left maxillary antrum extending to the left orbit and left ethmoidal air cells...

Undifferentiated pleomorphic sarcoma (UPS) is an extremely rare tumor that occurs in the head and neck region. Here, we report a unique case of a primary undifferentiated pleomorphic sarcoma in the orbital region. A 35-year-old woman presented with a progressive proptosis and periocular edema for 1 year. She had no previous history of surgery, skin malignancy, or radiation. Imaging tests showed an extraconal mass, not involving the muscles. The tumor was surgically removed and adjuvant radiotherapy was required after histological examination, which showed an undifferentiated pleomorphic sarcoma of the orbit...

OBJECTIVE One of the principles of the surgical treatment of craniosynostosis includes the release of fused bone plates to prevent recurrence. Such bone defects require a reossification process after surgery to prevent a cosmetic problem or brain vulnerability to damage. The objective of this study is to describe and analyze the radiological and clinical evolution of bone defects after craniosynostosis. METHODS From January 2005 to May 2016, 248 infants underwent surgical correction of craniosynostosis at HUiP La Fe Valencia; the authors analyzed data from 216 of these cases that met the inclusion criteria for this study...
