OBJECTIVE The purpose of this study was to perform histological and histometric analyses of the repair process of autogenous bone grafts fixed at rat calvaria with ethyl-cyanoacrylate adhesive. MATERIAL AND METHODS Thirty-two rats were divided into two groups (n=16), Group I - Control and Group II - Adhesive. Osteotomies were made at the right parietal bone for graft obtainment using a 4-mm-d...

Calvarial hemangiomas are rare benign tumours of the skull bone for which seizure as a presentation is unusual; neurological deficits are uncommon. We report a case of cavernous hemangioma of the parietal bone causing seizure disorder in a 47 year old man. The tumor was removed enbloc with satisfactory methylmethacrylate cranioplasty. Pathological examination confirmed the diagnosis. Patient re...

Primary intraosseous cavernous hemangiomas (PICHs) are benign vascular tumors that may involve any part of the body. PICH occurs more frequently in the spine and less commonly in skull. The earliest description in the English literature was in 1845 by Toynbee, who reported a vascular tumor arising in the confines of the parietal bone. Skull PICHs do not always have typical radiologic features a...

The McCune-Albright syndrome was described as a syndrome of polyostotic fibrous dysplasia, café au lait skin pigmentation, and autonomous endocrine hyperfunction in 1937. We report a 17-year girl with early menarche and accelerated growth for the past three years. The endocrinological examination showed slight rise of growth hormone with other hormones in normal range. The CT showed an expansiv...

Fibrous dysplasia is a benign fibro-osseous lesion progressing with one or more bone involvements in the skeleton. Even though it is a benign tumor, it may potentially transform into a malignant one. While the most frequently involved zones in the head-neck zone include the maxilla, mandible, parietal, occipital, and temporal zones, the involvement of the ethmoid bone is rather rare. This artic...

The patient had pneumocephalus due to a bony defect at the level of his scalp tumour. As shown in fig 1, the frontal lobes are compressed and the interhemispheric space between the two tips of the frontal lobes gives rise to the “Mount Fuji” sign, named after its resemblance to the silhouette of the Japanese volcano. A CT of the vertex on a bone window (fig 2) shows the scalp defect, with exten...

We present an 82-year-old woman, admitted for generalized status epilepticus, showing an osteolytic lesion of the right parietal bone associated with underlying focal brain pseudohypertrophy. A radiological diagnosis of diploic epidermoid cyst based on MRI characteristics was made. The aspect of focal brain pseudohypertrophy was probably caused by direct involvement of the underlying meningeal ...

A 30‐year‐old man presented with progressive blurred vision and cosmetic facial problems within 2 years ago. Neurological examination demonstrated impaired visual acuity and constricted visual field associated with both forehead and right side craniofacial deformity in the general examination. The craniofacial computed tomography (CT) scan showed expansion and thickening in right mandible, ante...

Intraosseous cavernous hemangiomas of the skull are rare. Meningiomas are quite frequently encountered in a neurosurgical practice. The association between these two entities is nevertheless very uncommon. The authors present a case of a 72-year-old woman suffering from headache. The MRI showed a parietal meningioma with adjacent thick bone. The meningioma and the bone were removed. The histolo...

(1) An incised wound semi-circular in shape, 4|inches in length, near the crown of the head, ou tiie left side of the median line; a portion of the skull (left parietal bone at its posterior inferior angle) by 2" having been entirely cut off in a slanting way, and the brain substance protruding through the cavity thus created. (2) Another wound, similar in shape and length to the above, but sit...
