BACKGROUND Cavernous hemangiomas are the most common orbital tumors in adults. Traditional orbitotomy approaches to resect these intraconal lesions are associated with patient morbidity due to difficulties with visualization and access in the region of the orbital apex. METHODS In this retrospective chart review and case series, the records of 5 patients who underwent endoscopic resection of ...

Idiopathic granulomatous inflammation is regarded as a histopathologic variant of an orbital pseudotumor and has a similar clinical presentation and treatment. However, the differential diagnosis including sarcoidosis, Wegener's granulomatosis, trauma, and infection must be ruled out. We present a 77-year-old man with a biopsy-proven lacrimal gland granulomatous inflammation of an unknown origi...

BACKGROUND Osteoid osteoma is a benign bone neoplasm which is seen in the long bones of appendicular skeleton. It is rarely seen in the cranium. Skull base osteoid osteoma is extremely rare and has been anecdotally reported. CASE PRESENTATION The authors report a case of a large osteoid osteoma of the ethmoid with intraorbital and intracranial extension in a 33 year old male patient. He prese...

Objectives In anatomic and radiologic morphometric studies, we examine a predictive method, based on preoperative imaging of the anterior cranial base, to define when addition of orbital osteotomy is warranted. Design Anatomic and radiographic study. Setting In 100 dry skulls, measurements in the anterior cranial fossa included three lines and two angles based on computerized tomography (CT) sc...

Background Access to the intraorbital optic nerve segment can be facilitated via a transcranial approach that allows access to the entire orbital cavity. The endoscopic endonasal approach (EEA) combined with a transconjunctival-medial orbitotomy represents an alternative technique to achieve the same goal. Objective Report a surgical technique that allows total resection of the intraorbital opt...

Hemangiopericytoma (HPC) is a rare tumor originating from the mesenchyme. We will describe the clinical presentations, radiological and operative findings, and pathological features of a patient with lacrimal gland HPC. The patient was a 26-year-old female who presented with swelling of the left upper eye lid progressing over the past 12 months. On ophthalmological examination, no visual impair...
