Ewing's sarcoma is an uncommon primary bone tumor. Primary Ewing's sarcoma of the cranium is extremely rare and constitutes only 1% of all Ewing's sarcoma cases. Usually, primary Ewing's sarcoma of the carnium manifests as an expansile osteolytic malignant bone tumor with or without intracranial extension. We report here the radiological findings of a case of Ewing's sarcoma mimicking a meningioma in an 18-year-old man.

Encephaloceles are known as rare craniofacial developmental anomalies which are herniation of cranial contents through a skull defect. Sphenoidal meningoencephalocele represents an important cause of reVersible visual loss. We report a rare case of pituitary adenoma accompanying sphenoidal meningoencephalocele with clival extension. Although the definitive diagnosis of cystic lesions in the sellar region before surgery is difficult, accurate diagnosis of these lesions is important to determine the type of treatment and predict prognostic outcome.

Multilobular tumour of bone (MTB) is an uncommon tumour and is usually located in the skull. A 13-year-old mixed breed dog was presented with a two-week history of progressively worsening vestibular dysfunction and cognitive abnormalities; it appeared demented and showed asymmetric ataxia and hypermetria of all limbs. The owner opted to have the animal euthanised. Necropsy revealed a large mass occupying the right occipital, parietal and temporal bones, severely compressing the cerebellum and the right occipital lobe. Histologically, it was characterised by the presence of multiple lobules containing osteoid or cartilage and separated by fibrous septae, features typical of MTB. Lung metastases were evident. To our knowledge, this is the first report of an MTB causing both severe cerebral and cerebellar compression and the second detailed report of an MTB of the occipital bone. MTB should be included in the differential diagnosis of bone tumours as well as in cases with central vestibular disease.

OBJECTIVE: The authors report an analysis of clinical data including incidence, clinical manifestations, diagnostic tools and surgical treatment of neoplasms of scalp and calvarium in adults. METHODS: The clinical, radiological, and pathological records of 67 patients who underwent mass excision in scalp or skull at our department during recent five years were reviewed. RESULTS: The mean age was 43 years(range 16 to 85 years) and male to female ratio was 42 : 25. There were 62 scalp and five calvarial masses. Among scalp masses, there were 52 tumors, three vascular lesions, three inflammatory lesions and four miscellaneous lesions. The scalp tumors were composed of 44 benign lesions and nine malignant lesions. The most common type of scalp tumor was lipoma, followed by epidermoid and dermoid. The calvarial masses consisted of four osteomas and one eosinophilic granuloma. Surgical excision was carried out in all cases. CONCLUSION: Most scalp and calvarial masses are benign lesions, however, surgical excision seemed to be indicated in most cases for diagnosis and treatment.

UNLABELLED: The patient was hospitalized for sudden hearing impairment for one day. PHYSICAL EXAMINATION: the blood pressure was 150/90 mm Hg, the tympanic membranes in both ears were complete and otopiesis. Audiogram showed total deafness in the right ear and slight sensorineural deafness at speech frequency and 80 db for high tone air conduction and 70 db for bone conduction at high frequency in left ear. Tympanogram showed "A" type in both ears and the ipsilateral and contralateral acoustic reflex in both ears were not induced. BAEP showed that the V wave threshold on the right was not induced and it was 50 dbnHL on the left. CT showed a limited low density area in the clivus. MRI showed a space-occupying lesion behind the basilar clivus and ahead of brain stem. Pathological examination showed CK(+), EMA(+), S-100(+) according to immunohistochemistry, which was in accordance with chondroid chordoma. DIAGNOSIS chondroid chordoma of clivus.
