A 60 year old lady presented with progressive increasing swelling over the scalp for 1 year and mild headache for 2 months. Examination revealed a non tender bony hard mass over the left parietal region. CT scan showed localized hyperostosis and thickening of the left parietal bone, with normal underlying brain parenchyma. The mass was surgically excised. Histopathology was suggestive of mening...

INTRODUCTION Gorham's disease is a rare bone disease, is characterized by the proliferation of thin-walled vascular channels associated with regional osteolysis. There have been fewer than 150 cases reported in the literature. Shoulder and pelvic region is common site. Skull is the least common site of involvement. CASE PRESENTATION We describe a case of a 35-year-old female of Indian origin ...

OBJECTIVE to compare the amount of new bone produced by Bio-Oss((R)) Collagen to that produced by collagen matrix in vivo. METHOD eighteen bone defects, 5mm by 10mm were created in the parietal bone of 9 New Zealand White rabbits. 6 defects were grafted with Bio-Oss((R)) Collagen. 6 defects were grafted with collagen matrix alone (positive control) and 6 were left empty (negative control). An...

Abstract The pan-sirenian Bauplan is conservative, probably owing to the constraints of adaptation an aquatic lifestyle. Gathering morphological data from extinct forms complex, resulting in poorly resolved phylogenies for stem pan-sirenians. Extant sirenians ossify falx cerebri and tentorium cerebelli, membranes dura mater brain attached parietal bone. Nevertheless, these ossifications are not...

We present a rare case of self-inflicted penetrating head trauma by a 34-year-old male who hammered four nails into his own head; he had been diagnosed with schizophrenia seven years before. On the physical examination, four nails were observed in the hairy scalp that had been driven into the cranium in the right temporal and parietal areas of the head. No cerebrospinal fluid fistulas were pres...

Malignant fibrous histiocytoma (MFH) is a rare primary neoplasm that constitutes less than 1% of the malignant tumors of bone, and involvement of the skull is very rare. We present a case of malignant fibrous histiocytoma of the skull, presenting an intraosseous lesion in a 43-yr-old woman. She had a rapidly growing, tender mass in the right parietal region. A plain radiograph showed an osteoly...

Extraskeletal mesenchymal chondrosarcoma (EMCS) is a rare malignant soft tissue tumor of chondroprogenitor cell origin. Originally, it was restricted to the bone only but that no longer case. Recent literature reports 20–33% these tumors occur at extraskeletal sites. We report one such case, in which involved anterior abdominal wall muscles and also had large intra- mass covered part peritoneal...

Purpose: Low intensity pulsed ultrasound stimulation (LIPUS) has been clinically applied to promote bone fracture healing in the orthopedic field. Thus, it is likely that LIPUS also stimulates bone regeneration in bone defects in the cranial-maxillofacial area. However, this has not been clearly proved. Furthermore, optimal time point and period of the application after the surgery has not been...
