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)
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)
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)
A 33-year-old man presented with a long history of intractable partial seizures with the first episode at the age of 18 years. The seizure frequency had increased in the recent past. CT imaging revealed a low attenuation lesion in the left frontal cortex with calvarial scalloping. MR imaging revealed a heterogeneous signal intensity lesion with involvement(More)
