ABSTRACT

Introduction: Posterior fossa tumours are common inpaediatric population; however their occurrence in adults is notrare. They form a major cause of morbidity and mortality ineither population. Some of these tumours like pilocyticastrocytomas are rewarding, others, like medulloblastomasmay have a poor outcome. This study aims to analyse theepidemiology and surgical outcomes of posterior fossa lesions.Materials and Methods: This is a retrospective study done atDepartment of neurosurgery S.M.S Medical college Jaipur fromJanuary 2017 to December 2017. It included 32 patients withposterior fossa lesions. Cerebellopontine angle lesionsschwannomas, epidermoids were excluded. Only lesionsinvolving the cerebellum or occupying the fourth ventricle wereincluded in the study. Their surgical outcome in terms ofcomplications and mortality were analysed.Results: Thirty –two patients, in the age group of 2years to 68years were included in the study. Cerebello-pontine anglelesions were excluded. Only lesions involving the cerebellum oroccupying the fourth ventricle were included in the study. Mostcommon lesion was medulloblastoma, followed by pilocyticastrocytoma, cerebellar abscess, haemangioblastoma,arachnoid cyst, exophytic tectal gliomas, tuberculoma,metastasis, epidermoid. They underwent surgery dependingupon the nature of lesion. Overall mortality was found in 9 of 32patients. Mortality was especially high in medulloblastomapatients (54.55%).Conclusions: Various lesions may affect the posterior fossa,varying from neoplastic malignant or benign lesions to infectiveand developmental lesions. Medulloblastoma is a commontumour in the paediatric population and carries a badprognosis.

ABSTRACT

INTRODUCTION- 1 Posterior fossa tumours are common in paediatric population ; however their occurrence in adults is not rare. They form a major cause of morbidity and mortality in either population. Some of these tumours like pilocytic astrocytomas are rewarding, others, like medulloblastomas may have a poor outcome. This study aims to analyse the epidemiology and surgical outcomes of posterior fossa lesions. MATERIALS AND METHODS – This is a retrospective study done at Dr. B.R.A.M. Hospital between April 2016 and June 2018. It included 32 patients with posterior fossa lesions.Cerebellopontine angle lesions- schwannomas, epidermoids were excluded. Only lesions involving the cerebellum or occupying the fourth ventricle were included in the study. Their surgical outcome in terms of complications and mortality were analysed. RESULTS-Thirty –two patients, in the age group of 2years to 68 years were included in the study. Cerebello-pontine angle lesions were excluded. Only lesions involving the cerebellum or occupying the fourth ventricle were included in the study. Most common lesion was medulloblastoma, followed by pilocytic astrocytoma, cerebellar abscess, haemangioblastoma, arachnoid cyst, exophytic tectal gliomas, tuberculoma, metastasis, epidermoid. They underwent surgery depending upon the nature of lesion. Overall mortality was found in 9 of 32 patients. Mortality was especially high in medulloblastoma patients (54.55%). CONCLUSIONS – Various lesions may affect the posterior fossa, varying from neoplastic malignant or benign lesions to infective and developmental lesions. Medulloblastoma is a common tumour in the paediatric population and carries a bad prognosis

ABSTRACT

Von Hippel–Lindau (VHL) disease is a rare autosomal dominantly inherited multisystem disorder characterised by the development of a variety of benign and malignant tumours. We report a case of VHL disease that was inherited by a daughter from her father, who both presented at a young age with progressive headache and were found to have a posterior fossa haemangioblastoma (HB) on magnetic resonance imaging (MRI). Multiple benign pancreatic and renal cysts were also noted in both patients.

ABSTRACT

CT demonstration of 4 cases of infratentorial haemangioblastoma and 2 cases of supratentorial malignant haemangiopericytoma conformed surgically and pathologically in our hospital were analyzed in this article. We think, that Infratentorial cystic haemangioblastoma has typical CT demonstrations. In general, the qualitative diagnosis of it may be achieved. CT demonstration of supratentorial malignant haemangiopericytoma is atypical, so it is difficult to differentiate from other intracranial tumors and brain abscess. In the end it is only defined by histology.
