ABSTRACT

Computerized tomography (CT) scan and operative observations, and histolopathogical findings of 25 cases of intracranial hemangioblastoma were correlated. Solid hemangioblastomas showed a large number of thin-walled capillaries and abundant stromal cells with eosinophilic cytoplasm. Tumors with a cystic component and a mural nodule had a large number of stromal cells with vacuolated cytoplasm and microcysts.

ABSTRACT

Metastasis of intraventricular meningiomas through CSF pathways is a rarity and only 4 cases have been reported in world literature describing meningiomas which were intraventricular and malignant. Here we report a case of benign intraventricular meningioma which had spread through CSF pathways, the recurrences as well as the primary tumor being benign in nature.

ABSTRACT

Traumatic intracranial aneurysms constitute less than 1% of all intracranial aneurysms. A case of traumatic distal anterior cerebral artery aneurysm in 18 months old child, treated successfully by microsurgical excision of aneurysm is being reported, along with review of the literature.

ABSTRACT

Non-neoplastic, non-inflammatory cysts of the central nervous system may cause symptoms because of pressure, rupture or secondary inflammation. A total of 145 cases of cysts were reviewed during a study period of 12 years. The clinical details and histological features were noted in all cases. During this period 53 epidermoid cysts, 16 dermoid cysts, 38 colloid cysts, 23 arachnoid cysts, 5 neurenteric cysts, 5 ependymal and glial cysts, 2 Rathke's cleft cysts and 3 unclassified cysts were encountered. The possible histogenesis is also discussed.

ABSTRACT

AIM: To study the pattern of central nervous system aspergillosis in a tropical country. MATERIAL AND METHODS: Case records of patients with CNS aspergillosis seen by the authors in a university hospital in south India were reviewed. RESULTS: Of the 21 patients seen during the study period, 16 (76%) patients had intracranial invasion by contiguous spread from paranasal sinuses and one had from ear. Predisposing risk factors were present in two (12.5%) patients with sinocranial aspergillosis and in both patients with disseminated form. Skull bases syndromes were the presenting features in 13 patients, six patients presented with features of intracranial space occupying lesion and two patients had stroke like presentation. CT scans showed intracranial extradural contrast enhancing mass lesions in the anterior, middle or posterior cranial fossa in addition to mass lesions in the paranasal sinuses in 13 patients with sinocranial aspergillosis and in seven orbital lesions. Intracerebral contrast enhancing mass lesion was the CT finding in both the patients with solitary cerebral aspergillus granuloma and in the patient with otocranial aspergillus granuloma. Well-formed granuloma with dense fibrosis was the histological feature in patients with sinocranial and otocranial aspergillosis. Angioinvasion was the pathological feature in both the patients with disseminated form of aspergillosis. Surgical treatment was sub-radical in our series. Survival rates were not good even after surgical and antifungal chemotherapy. CONCLUSIONS: This study suggests that in this part of the world sinocranial aspergillosis is the most common form of histologically verified CNS aspergillosis. Associated predisposing factors and immune status of the host determine the clinical syndrome and type of pathology in patients with CNS aspergillosis.

ABSTRACT

A 50 year old female who was operated for atrial septal defect 8 years back, presented with clinical features suggestive of subarachnoid haemorrhage (grade I, Hunt and Hess). CT scan of brain revealed haemorrhage in all the supratentorial basal cisterns, sylvian cistern and small haematoma in the left occipital lobe. Conventional CT and MR angiography revealed aneurysm in relation to distal part of the calcarine branch of the left posterior cerebral artery (PCA). Left occipital craniotomy in prone position followed by deep dissection in the occipital lobe showed fusiform aneurysm of the distal part of the calcarine branch. PCA aneurysms constitute only 0.2 to 1% of all intracranial aneurysms and among them distal PCA aneurysms are most rare, constituting only 1.3%. They too are mostly seen at the bifurcation of the PCA. The present case however, is unique in the sense that it has developed as a fusiform aneurysm in the distal part of the calcarine branch. To the best of our knowledge this is rare among the rarest.

ABSTRACT

A seventy eight year old man sustained penetrating injury to right orbit about 15 years ago. Later he developed right orbital infection leading to phthisis bulbi. Two months before admission he developed CSF leak from the right orbit, tension pneumocephalous and meningitis. A rare case of CSF orbitorrhoea is reported here along with the discussion on mechanisms and management.

ABSTRACT

Cavernous hemangioma is the most common benign intraorbital tumor in the young and middle aged, producing painless proptosis. It is common in females in whom it may enlarge during pregnancy. There have however been very few series reported on this entity.

ABSTRACT

Positive neurological phenomena of cerebral palsied, especially spasticity are best relieved by neurosurgical procedures. But the procedures are indicated only in those cases who have developed resistance to nonsurgical therapies, especially rehabilitative therapy. However, surgical procedure cannot teach a child how to perform motor functions. Therefore, rehabilitative therapy plays immense role in development of motor functions which can be improved best during the physical developmental and learning ability age of the child. Therefore, it is recommended to start neurodevelopmental therapy at a few weeks age of the child, and perform the neurosurgical procedure as soon as the child develops resistance to the therapy. The child has to resume back to therapy following the surgery for further motor development. There are various neurosurgical procedures for the relief of positive neurological phenomena. The present article includes brief description of the procedures and review of the literature. The authors feel that the selective posterior rhizotomy is perhaps the best procedure among all other ablative procedures for the relief of diffuse spasticity of both the lower limbs in strictly selected cases.

ABSTRACT

Pulmonary function tests (VC, FEV1% and FEF25-75%) were evaluated in 15 to 18 years age workers employed in slate pencil industry exposed to silica dust, in wool carpet industry exposed to wool dust and in diamond cutting and polishing exposed to carbon dust. These values were compared with the values obtained in clinically healthy non-smokers of the same age group. The results revealed significant impairment of VC in diamond workers, and FEF25-75% in slate pencil workers. When the values were observed according to smoking habits in diamond workers, VC, FEV1 and FEF25-75% were all significantly reduced in smokers whereas in non-smokers only VC was lowered significantly. Among slate pencil workers FEF25-75% was significantly reduced in both smokers and non-smokers. Wool dust exposed workers showed reduced values than normal subjects. The detailed results including the prevalence of various pulmonary impairments were presented.

ABSTRACT

The effect of nifedipine, a calcium antagonist on fasting blood glucose level, glucose tolerance, glucose-induced insulin and glucagon secretion was studied in healthy nondiabetic volunteers. Nifedipine 10mg twice daily for four weeks did not affect fasting blood glucose level, glucose tolerance, glucose-induced insulin and glucagon secretion.
