Solitary fibrous tumours are rare spindle cell tumours that generally arise from the pleura but on rare occasions arise in other locations such as the head and neck region, stomach and retroperitoneum. Very few reports exist on the imaging findings of these tumours in extra pleural sites such as the mesentery. We report the computed tomography (CT) imaging(More)
Frontonasal encephaloceles involve herniation of meninges and brain tissue through defects in the floor of the anterior cranial fossa affecting the frontal, ethmoid and nasal bones. Subependymal nodular heterotopias are malformations of cortical development resulting from abnormal neuronal migration. This report describes the coexistence and association of(More)
The authors describe imaging patterns of intracranial metastases in 2 children with grade 4 neuroblastoma. Central nervous system metastases from neuroblastoma are extremely rare and may involve the cerebral parenchyma, leptomeninges, or dura. Cerebral parenchymal metastases can be cystic with mural nodules or solid with hemorrhagic elements. The first(More)
CASE REPORT A 3-day-old baby was referred to our institution with seizures since birth and a presumptive diagnosis of cerebral tumor detected by prenatal ultrasound. Computed tomography (CT) and Magnetic Resonance (MR) imaging performed immediately after birth revealed the presence of an enhancing mass in the left cerebral hemisphere. DISCUSSION The(More)
This report describes the case of a 50-year-old woman with carcinomatous meningitis from squamous cell carcinoma of the uterine cervix. Ultrasound showed an irregular hypoechoic mass in the cervix. Contrast enhanced computed tomography imaging revealed intense linear enhancement along the falx cerebri suggestive of pachymeningeal metastasis with involvement(More)
PURPOSE Diffusion-weighted imaging (DWI) is a widely used medical imaging modality for diagnosis and monitoring of cerebral stroke. The identification of exact location of stroke lesion helps in perceiving its characteristics, an essential part of diagnosis and treatment planning. This task is challenging due to the typical shape of the stroke lesion. This(More)
We describe the proton ((1)H) magnetic resonance spectroscopic (MRS) imaging of central neurocytoma (CNC), a rare benign intraventricular neuronal tumor. Multivoxel MR Spectroscopy is a feasible and reproducible non-invasive tool for the specific diagnosis of CNC and to distinguish CNC from other intraventricular tumor types. The detection of glycine and(More)
PURPOSE Desmoplastic infantile gangliogliomas (DIG) are rare benign intracranial neoplasms of early childhood with involvement of superficial cerebral cortex and leptomeninges. The purpose of the study was to determine the alterations in metabolite ratios occurring in the neoplasm and combine with magnetic resonance (MR) imaging features to narrow down the(More)
Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological phenomenon seen in a wide spectrum of clinical conditions and is characterized clinically by headache, altered mental status, visual loss and seizures and reversible neuroimaging findings. This study evaluated MR imaging in PRES in a clinical oncology setting. MR findings may be(More)
We report an extremely rare case of malignant hemangiopericytoma (HPC) of the parotid gland and its metastatic spread to lung, liver, and skeletal muscle. Computed tomography (CT) imaging, histopathological and immunohistochemical methods were employed to study the features of malignant HPC and its metastases. CT imaging was helpful to determine the exact(More)
