1/61. Intracranial Castleman's disease of solitary form. Case report.This 62-year-old woman presented with clumsiness in her right hand. magnetic resonance imaging demonstrated a small lesion mimicking a meningioma, which had arisen from the tentorium and contained notable edema. Full recovery was achieved by total removal of the lesion, which was diagnosed as a lymphoid mass resembling giant lymph node hyperplasia on histological examination. The lack of notable findings on whole-body and laboratory studies was compatible with a rare case of intracranial Castleman's disease of solitary form. The authors document clinical, neuroradiological, and pathological features of this rare disease.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/61. Atypical measles infections in leukaemic children on immunosuppressive treatment.One case of giant-cell pneumonia and two of encephalopathy, all due to measles infection in children in leukaemic remission on immunosuppressive treatment, were seen recently. The clinical syndromes were variable and atypical and the antibody responses unpredictable. Conventional doses of pooled immunoglobulin failed to protect the two children to whom it was given. Degeneration rather than inflammation seems to characterise the encephalopathy in immunosuppressed children infected with measles virus.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
3/61. A giant intracranial mucocele associated with an orbitoethmoidal osteoma. Case report.The authors present a rare case of a giant intracranial mucocele associated with an orbitoethmoidal osteoma in a patient suffering from a generalized convulsive disorder. The broad pedicle of the osteoma had penetrated the cribriform plate and extended intracranially to form a nodular mass in the olfactory groove. The intracranial portion of the osteoma was surrounded by a mucocele. Both the cyst wall and multilayered intracystic septations of the mucocele were indented by layers of the osteoma. Although the extracranial portion adhered to the mucosa of the ethmoidal sinus, there were no signs of sinus obstruction. No direct communication other than the osteoma was identified between the mucocele and the ethmoidal mucosa. The large cerebral defect, which the mucocele occupied, communicated directly with the lateral ventricle without any intervening membranous structures. A frontal craniotomy is recommended for exposure of the lesion and plastic repair of the dural defect.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
4/61. Giant hypothalamic hamartoma with cystic change: report of two cases and review of the literature.We describe the MRI findings in two patients with giant hypothalamic hamartomas with cystic areas. Cystic change within hypothalamic hamartomas is rarely reported in the literature.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
5/61. Intracranial spread of a giant frontal mucocele: case report.A giant mucocele eroded both the anterior and posterior wall of the frontal sinus and infiltrated the dura mater. Its extracranial growth caused a frontal bony prominence. The tumour and part of the dura were resected. A 12 x 6cm defect in the dura was repaired with a freeze-dried patch. A split-thickness bone graft from the right parietal region was used to repair the anterior frontal bony defect. The result one year later was satisfactory. Spiral computed tomography with thr ee-dimensional reconstructions excluded any recurrence of the tumour and showed good integration of bone grafts.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
6/61. September 2000: 15 year old girl with intracranial lesion.The September COM: We reported the case of a 15 year old white girl with solitary brain cortical lesion clinically mimicking meningioma. Microscopic examination revealed histiocytic lesion with foamy and giant cells predominately of Touton type. Subsequent clinical examination did not reveal any similar lesion in the skin or in other location. Expression of S-100 protein in histiocytes is unusual finding, but has been reported recently in juvenile xanthogranulomas (JXG). The only specific ultra-structural finding differing JXG from histiocytic neoplasm of Langerhans' cells histiocytosis type seems to be Birbeck granules.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/61. Intracranial giant cell reparative granuloma arising from the temporal lobe area: MR findings.SUMMARY: We present an unusual case of a giant cell reparative granuloma arising from the left temporal lobe area of a 38-year-old man and provide clinical and MR findings. Current diagnosis and treatment options are also discussed.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
8/61. Giant ependymal cyst of the temporal horn -- an unusual presentation. Case report with review of the literature.Primary benign cystic lesions in the brain are uncommon. However, extracerebral cysts like arachnoid cyst, epidermoid cyst and craniopharyngiomas are fairly common lesions. Also, colloid cyst in the third ventricle, dermoid cyst and endodermal cyst in the extracerebral location are not uncommon. On the contrary, intraventricular ependymal and choroidal cysts in the intraventricular location are infrequent. Surgical intervention is warranted in cysts, which produce a mass effect and raised intracranial pressure. We present an interesting case of a giant intraventricular ependymal cyst in the temporal horn in a 14-year-old boy, who presented with recent onset of headaches and epilepsy. He also had long-standing progressive proptosis of the left eye and left temporal bossing. Excision of this cystic lesion was curative. Interesting clinical and neuroimaging features are presented.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/61. Two cases of melanose neurocutanee with development of malignant melanoma: a microspectrophotometric and electron microscopic study.Two cases of neurocutaneous melanosis with development of malignant melanoma in the Japanese are presented. The first case was a 4-year-old boy in whom a retroperitoneal melanoma appeared with giant nevi, and cerebral and spinal melanosis. The second case was a 39-year-old man, in whom a primary leptomeningeal melanoma developed with leptomeningeal melanosis and smaller pigmented nevi. Microspectrophotometric and electron microscopic studies were made on the neoplastic and non-neoplastic melanotic tissues to elucidate the histogenesis of this rare disorder. Two different patterns of nuclear dna histograms, corresponding to melanosis and melanoma, were obtained by microspectrophotometry, Considerable variation in the ultrastructure of the melanocytes was seen by electron microscopy.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/61. Immunohistochemical study of six cases of Taylor's type focal cortical dysplasia: correlation with electroclinical data.PURPOSE: Cortical specimens from six patients operated on for drug-resistant epilepsy diagnosed as Taylor's type focal cortical dysplasia were submitted to neuropathological and immunohistochemical studies. methods: All patients were submitted to presurgical investigations including clinical and neuropsychological evaluations, EEG/video telemetry of ictal and interictal events, magnetic resonance imaging, and ictal and interictal single-photon emission computed tomography (SPECT). Recordings from electrocorticography (ECoG) were obtained in four cases and from subdural electrode implantation in two. Postsurgical follow-up was assessed according to Engel's score. immunohistochemistry (IHC) was processed for parvalbumin (PV), calbindin D28-K (CB), nonphosphorylated neurofilaments (SMI-311), glial fibrillary acidic protein (GFAP) in all cases. RESULTS: We found continuous/quasi-continuous spikes and sharp-wave patterns in three cases and frequent repetitive bursting of polyspikes and ECoG seizures in two cases. Every patient showed cortical dyslamination, abnormal and giant neurons, and balloon cells. GFAP immunoreactivity was found in astrocytes and some balloon cells that were less intensely stained. Nonphosphorylated neurofilaments SMI-311 immunoreactivity was found in normal and giant neurons and in some balloon cells, making visible thin neuropils. PV immunoreactivity was present in normal interneurons and in fibers in layers IV-V. PV-negative balloon cells were surrounded by abundant PV-positive fibers. CB immunoreactivity was found mostly in interneurons in layers II-III. CONCLUSIONS: Our research is inconclusive. More cases should be investigated, and we must draw more accurate anatomic correlations between the ECoG recordings and surgical specimens studied with IHC.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
