1/20. Sellar chondroma--case report.A 12-year-old boy presented with right visual disturbance. Skull radiography and computed tomography (CT) showed an irregular deformity of the sella turcica, hypertrophic change of the dorsum sellae, and an inhomogeneously calcified mass in the sella turcica. Magnetic resonance (MR) imaging demonstrated the mass lesion filled the hypophyseal fossa, and extended to the dorsum sellae, right cavernous sinus, and right suprasellar region. The Dolenc pterional combined epidural and subdural approach was carried out. The histological diagnosis was chondroma. Sellar chondroma requires relief of the compression to the chiasm or optic nerve as soon as possible, so partial resection can still be beneficial. However, follow-up MR imaging or CT, visual examination, and control of pituitary dysfunction are required after the operation.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/20. Extraskeletal chondroma as a cause of carpal tunnel syndrome: a case report.We report a case of carpal tunnel syndrome as a result of an extraosseous chondroma in a 47-year-old gentleman. This case demonstrates the importance of clinical examination and occasional radiographs in this not uncommon condition. We also highlight that this well known entrapment syndrome is not only caused by the common causes that we all know, but also any space-occupying lesion in the carpal tunnel compressing the median nerve.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
3/20. Intracranial chondrosarcoma--case report.The authors report the case of a 54-year-old male who was found to have a large intracranial chondrosarcoma at the site from which chondromas had been partially removed twice, 6 and 10 years previously. On the third admission, the second through tenth and the twelfth cranial nerves on the right side were involved. Computed tomographic scans showed a large mass in the right middle and posterior fossae and the right ethmoid sinus. angiography demonstrated an extradural mass in the right middle fossa. The tumor in the middle and posterior fossae was subtotally removed, and second, third, and eighth cranial nerve function improved postoperatively. Histological examination of tumor specimens showed active proliferation of poorly differentiated cartilagenous cells, suggestive of sarcomatous transformation of the pre-existing chondroma. It is emphasized that chondromas should be removed as completely as possible and that patients must be followed carefully after surgery.- - - - - - - - - - ranking = 2keywords = nerve (Clic here for more details about this article) |
4/20. Chondroma of the lumbar spine, a rare cause of sciatica: case report.A case of chondroma of the lumbar spine causing nerve root compression is presented. This benign tumor was completely removed, resulting in relief of all radicular symptoms.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
5/20. Cervical osteochondroma (C2 level) with vertebral artery occlusion and second cervical nerve root irritation.A case of osteochondroma arising from the C2 transverse process, responsible for vertebral artery compression with complete occlusion and C2 nerve root irritation with C2 neuralgia, is reported. Complete surgical removal was achieved via the lateral anterior approach.- - - - - - - - - - ranking = 5keywords = nerve (Clic here for more details about this article) |
6/20. Synovial chondromatosis of the temporomandibular joint with intracranial extension. Case report.The authors report the unusual presentation of an intracranial extension of synovial chondromatosis of the temporomandibular joint. The patient presented with a peripheral facial nerve paralysis and anacusis. Computerized tomography revealed the lesion, but fine-needle biopsy was inconclusive. craniotomy with removal of the tumor was performed, and pathological studies confirmed the diagnosis. The facial nerve dysfunction was thought to be secondary to direct neural compression.- - - - - - - - - - ranking = 2keywords = nerve (Clic here for more details about this article) |
7/20. Lockjaw secondary to skull base osteochondroma: CT findings.Osteochondromas arising from the long bones, pelvis, or scapulae are common. However, osteochondromas originating from the base of the skull are extremely unusual. Although these tumors are histologically benign, intracranial extension and their close proximity to the cranial nerves may require complex surgery. We present a case in which CT clearly delineated an osteochondroma arising from the base of the skull. The tumor had created a fusion with the ipsilateral coronoid process of the mandible, thus causing lockjaw.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
8/20. Extraarticular chondromatosis of the hand. A case report.We present an uncommon case of large nonarticular chondromatosis of the hand. Some of the foci were found to cause compression of the median nerve, the ulnar artery, and also triggering of the third finger. The fourth lumbrical muscle was involved as well. A thorough, but not complete, excision with preservation of the median nerve and ulnar artery was performed. No recurrence was found during 5 years of follow-up.- - - - - - - - - - ranking = 2keywords = nerve (Clic here for more details about this article) |
9/20. Rare sacral space-occupying lesions, their surgical management and reconstructive measures involved.Nine cases of space-occupying lesions of the sacral bone are presented. The problems of the clinical diagnosis, which in many cases comes too late, are discussed together with the indications for surgical treatment in this special group of tumours. The main clues are provided by the changes in the x-rays as well as the more modern imaging techniques (CT and MRI). The surgical technique aims at a most radical tumour removal with preservation of the sacral nerve roots, after which stabilisation of the sometimes weakened pelvic girdle may be necessary. The good prospects of complete removal of these tumours of the sacrum with satisfactory results seem to be very little known and justifies further dissemination of this information.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
10/20. Synovial chondromatosis presenting with peripheral nerve compression--a report of two cases.We report two cases of synovial chondromatosis presenting with peripheral nerve compression syndromes involving respectively the median nerve at the wrist and the posterior interosseous nerve at the elbow. Only one previous instance of nerve compression due to this condition has been described, involving the ulnar nerve at the elbow. In one of our cases the disease process was at an early stage in its natural history and in the other at an advanced stage. The occurrence of nerve compression was related to the site rather than the stage of the disease. Full recovery followed local excision with decompression of the peripheral nerve involved.- - - - - - - - - - ranking = 11keywords = nerve (Clic here for more details about this article) |
