Aspergillus sinusitis is an infection that can cause high mortality without appropriate treatment. The infection is not only found in immunocompromised patients, but also in immunocompetent patients. Management approaches to Aspergillus sinusitis include surgical debridement and intravenous or oral antifungal agents, including traditional intravenous amphotericin B. Here we describe a case of A...

True ossification of the face spaces is a very rare clinical entity. We present a rare case of unilateral ossification of infratemporal space the in an 11-years old male with swelling in the right temporal and orbital area. His medical history was unremarkable. Radiographic evaluation with spiral CT scan revealed separated ossified particles inside of infratemporal space. After 2 separate proce...

Olfactory groove schwannoma is a very rare tumor breaking through the skull base and orbit. The tumor may also extend to the subfrontal region intradurally. A case of olfactory groove schwannoma in a 35-year-old female, originating from the left olfactory groove with left proptosis, diplopia, supra-orbital mass, and gross intracranial extension is reported. The presence of bony scalloping on CT...

syndrome. The cerebellum within those cephaloceles is usually dysplastic and gliotic. Plexiform NF, hallmark of NF-I are found in 30-40% of all patients with NF-I. They usually arise along the axis of a major nerve, are unencapsulated and infiltrate producing fusiform appearance. They commonly occur along orbital division of V nerve, but other areas are not exempt often associated with sphenoid...

Purpose To radiologically examine for the presence of bony remodeling of the orbit in thyroid eye disease (TED). Methods Computed tomography (CT) scans of 248 orbits of 124 patients with TED and 185 orbits of 138 controls were retrospectively reviewed, and the following parameters measured: the angle of the inferomedial orbital strut (AIOS), the angle of the medial wall (AMW), and the diamete...

Combining precise B,V photometry and radial velocities, we have been able to derive a firm orbital solution and accurate physical parameters for the newly discovered eclipsing binary HD 23642 in the Pleiades open cluster. The resulting distance to the binary and therefore to the cluster is 132±2 pc. This closely confirms the distance modulus obtained by classical main sequence fitting methods (...

The first complete orbital solution for the double-lined spectroscopic binary system γ 2 Velorum, obtained from measurements with the Sydney University Stellar Interferometer (SUSI), is presented. This system contains the closest example of a Wolf-Rayet star and the promise of full characterisation of the basic properties of this exotic highmass system has subjected it to intense study as an ar...

PURPOSE To repair the segmental orbital rim defects of dogs with three-dimensional (3D) tissue-engineered constructs derived from culturing autogenous bone marrow stromal cells (BMSCs) on β-tricalcium phosphate (β-TCP) scaffolds. METHODS A 25-mm segmental defect on the canine inferior orbital rim was created. BMSCs were isolated and osteogenically induced in vitro, then were seeded onto 3D β-...

PURPOSE To investigate the results of graded decompression of orbital fat and walls in Graves' orbitopathy (GO) considering the degree of proptosis reduction at surgery and preoperative computed tomography (CT) findings. METHODS This is a retrospective interventional case series. Graded orbital fat and wall decompression was performed in 90 orbits of 55 patients. In patients with enlarged ext...

A NUMBER of bone diseases may affect the orbital bones decreasing the orbital volume and narrowing the optic canal, giving rise to unilateral exophthalmos and usually optic atrophy, simulating clinically an orbital tumour. Among such diseases are osteitis deformans (Paget, 1876); leontiasis ossea (Virchow, 1896); osteopetrosis (Albers-Schonberg, 1904), and the generalized and localized osteitis...
