Prostate cancer is second most common with frequent metastasis occurring to bone. We report a unique case of soft tissue and bony orbital from carcinoma prostate. The patient presented after defaulting the advised treatment. He responded well radiation therapy lesion regressed completely. Our was diagnosed have an oligo-metastatic non-compliant treatment us proptosis, which later be prostate ca...
The mean distance between the apices of the maxillary posterior teeth and the floor of the maxillary sinus was measured from computed tomographic display data from 12 autopsy specimens and 38 human subjects. The distance from these apices to the adjacent lateral bony surfaces was also measured. The apex of the mesiobuccal root of the maxillary second molar was closest to the sinus floor (mean 1...
introduction: skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.case: 11 month female child had a trivial fall while standing near a bucket. the child developed fracture of right clavicle and left orbital swelling which was inadequately treated. this resulted in in spread of infection to...
AIM Lateral orbitotomy is a well-known approach for lesions of the lateral orbital cone. It is still appropriate for laterally situated tumors although contemporary cranial base approaches were defined and developed within the last decades. MATERIAL AND METHODS Here we report 10 orbital lesions operated with lateral orbitotomy, nine of which were extraconal. Cholesterol granuloma, arachnoid c...
BACKGROUND Orbital rhabdomyosarcoma (RMS) in childhood has an excellent survival rate after chemotherapy and radiation, and mutilating surgery can often be avoided. CASE REPORT As a rarity we present an unfortunate disease course in a child suffering from orbital embryonal RMS which did not enduringly respond to multimodal therapy including local excision and exenteration orbitae. After short...
BACKGROUND AND PURPOSE The possible relationship of orbit deformities in neurofibromatosis type 1 (NF1) to plexiform neurofibromas (PNFs) have not been fully elucidated. Our purpose was to review orbital changes in patients with craniofacial NF1. METHODS We retrospectively reviewed CT and MR imaging abnormalities of the orbit in 31 patients (18 male, 13 female; mean age, 14 years; age range 1...
BACKGROUND Mucoceles are slowly expanding cystic lesions with respiratory epithelium containing mucus most commonly affecting the frontal and ethmoidal sinuses. They are caused by obstruction of sinus ostium. Mucoceles exert pressure on the bony boundaries and due to the proximity to the brain and orbit extension to these areas are common. CASE PRESENTATION A case of a frontal mucocele with a...
BACKGROUND MPAs (minor physical anomalies) frequently occur in neurodevelopmental disorders because both face and brain are derived from neuroectoderm in the first trimester. Conventionally, MPAs are measured by evaluation of external appearance. Using MRI can help overcome inherent observer bias, facilitate multi-centre data acquisition, and explore how MPAs relate to brain dysmorphology in th...
