We report a case of a young male who received multiple surgical treatments for repeated recurrence of skull base mesenchymal chondrosarcoma (MC). When the patient was 18 years old, we subtotally removed the skull base MC and he was treated with stereotactic radiosurgery for remnant tumors in the left cavernous sinus. After 30 months, we removed residual tumors that had regrown partially, via combined endonasal endoscopic and orbitozygomatic approaches. Over the next 65 months, the patient refused radical resection, and received six salvage surgeries, two stereotactic radiotherapies, and five stereotactic radiosurgeries for repeated recurrence...

Optic nerve hemangioblastoma (ONH) is a rare tumor that is usually unilateral and most commonl occurs in the context of von Hippel-Lindau (VHL) disease. Differential diagnosis is based on clinical history and imaging. Magnetic resonance imaging with gadolinium enhancement is the most useful imaging modality as it can reveal flow voids and an absence of dural attachment, differentiating ONH from other more commonly encountered optic nerve tumors. ONH are usually well-circumscribed vascular lesions composed of stromal cells and vascular endothelial cells...

Orbital invasion of pituitary adenomas has been previously reported. In this report, the authors describe a 71-year-old female with a prolactinoma that presented with invasion of and apoplexy within the orbit. The patient underwent exenteration, followed by rapid tumor recurrence and growth. Given the hemorrhagic nature of the tumor, she subsequently underwent preoperative embolization and surgical resection. This case is notable in that it illustrates both apoplexy of a pituitary tumor within the orbit and the benefit of presurgical embolization...

Orbital location of extraskeletal osteosarcoma is extremely rare with only 4 cases reported so far in the English literature. We present the case of a 32-year-old female who presented with proptosis and complete loss of vision of the left eye. Contrast-enhanced computed tomography scan showed a densely calcified lobulated lesion in the left optic nerve showing strong enhancement. A left fronto-occipito-zygomatic osteotomy was conducted and a greyish brown tumor was identified. Histopathological and immunohistochemical examination of the curetted material revealed it to be extraskeletal osteosarcoma...

PURPOSE: Orbital inflammation can be idiopathic or in the context of a specific disease and it can involve different anatomical orbital structures. On imaging, inflammatory disease is frequently mistaken for infection and malignant tumors, and its underlying cause is often not determined. Through this article we aim to improve orbital inflammation diagnosis and underlying inflammatory diseases recognition. METHODS: The imaging protocols and characteristics of orbital inflammation were reviewed...

For removal of tumors and foreign bodies from the orbit, for treatment of severe inflammatory diseases, and for repositioning of bone fragments following fractures or during reconstruction of the bony orbit, several different surgical approaches are available. During the past decade, improved understanding of the pathology and pathophysiology of particular orbital diseases, advancements in clinical endoscopy and microscopy, the introduction of modern imaging techniques for preoperative visualization of pathologic findings, modern approaches to orbital reconstruction, as well as developments in adjuvant therapy have led to a reduction in invasiveness and development of the modern minimally invasive surgical approaches to the orbit usually used today...

Undifferentiated pleomorphic sarcoma is a malignancy of mesenchymal origin, which was previously known as malignant fibrous histiocytoma. It is known to occur on rare occasion as a primary orbital tumor, but no known cases of metastatic orbital involvement have been reported since 2002, when the reclassification of these tumors took place. The authors report a patient who presented with a metastasis to the left orbit 2 years after undergoing treatment of a high-grade undifferentiated pleomorphic sarcoma of the right thigh...

Skeletal cavernous hemangiomas are rare, benign tumors that may involve the supraorbital rim and orbital roof. However, such involvement is extremely rare. We report a case of skeletal cavernous hemangioma of the frontal bone involving the orbital roof and rim. En bloc excision and reconstruction, using a calvarial bone graft for the orbital roof and rim defect, was performed. It is important not only to perform total excision of skeletal cavernous hemangiomas, but to properly reconstruct the defects after the total excision since several complications can arise from an orbital roof and rim defect...

Cavernous hemangioma (CH) is the most common benign tumor of the orbit which can expand the bony orbit by gradual growth of a large tumor. In this article, the authors report a 28-year-old man presented with a longstanding unilateral proptosis secondary to a huge orbital CH which also caused optic disc deformation and bone erosions in the adjacent orbital walls. The optic disc deformities resolved after the tumor removal.

Orbital metastasis is a rare event, and metastatic disease affecting the extraocular muscles is an even less frequent complication of solid tumors. Herein, we report an unusual case of ptosis as the initial presentation of an invasive breast cancer. A 68-year-old woman presented with III and VI partial nerve paresis, secondary to a compressive retrobulbar mass. Magnetic resonance imaging revealed an infiltrative lesion involving the extraocular muscles. Tissue biopsy yielded a result compatible with metastasis to the orbit, with immunohistochemistry analysis suggesting breast as the primary organ...

BACKGROUND The clivus is a depression in the anterior occipital bone of the skull base, posterior to the dorsum sellae, at the junction with the sphenoid bone. Chordoma is a rare tumor arising from embryonic remnants of the notochord and can be locally aggressive with a tendency to recur. The optimal management of this rare tumor remains controversial. A report of a case of recurrent chordoma of the clivus is presented to illustrate the value of volumetric three-dimensional (3-D) reconstruction with computed tomography (CT) and magnetic resonance imaging (MRI) to determine optimal surgical management...

Introduction: Reactive lymphoid hyperplasia (RLH) is a rare and benign lesion found in organs of the gastrointestinal tract, skin, lung, orbit, and more rarely in the liver. Due to its similar appearance on imaging, it is hard to differentiate from primary liver malignancies. The following is a case report of a patient presenting with a suspicious liver lesion found to be RLH associated with primary biliary cirrhosis (PBC), after surgical resection. Presentation of Case: A 54-year-old woman presented with nonspecific abdominal pain, and her workup included axial imaging of the abdomen that showed a suspicious lesion in her liver...
