Incidental finding of metastatic malignancy involving the sphenoid sinus on a cone-beam computed tomographic scan: A case report

Abstract An 8-year-old boy presented in coma and was found to have a massive posterior fossa hemorrhage on computed tomographic scan. Autopsy disclosed a large cerebellar hematoma within a mixed glioma containing both juvenile pilocytic astrocytoma and oligodendroglioma. It is postulated that the hemorrhage originated from the oligodendroglial component of the tumor.

Progressive Necrosis

Abstract Gamma knife surgery employing a central dose of 70 Gy and a peripheral dose of 25 Gy caused progressive necrosis and shrinkage of a recurrent solitary metastasis of a cerebral hypernephroma, as verified by computed tomographic scan 2 and 4 months after treatment. Gamma knife surgery was an effective palliative treatment for this cerebral metastasis and was an alternative to craniotomy with microsurgical removal.

Multiple Nodules

We report the case of a 69-year-old man with acute pulmonary echinococcosis. A computed tomographic scan of the thorax revealed the presence of multiple nodules in both lungs, and laboratory tests showed eosinophilia and the presence of antibodies against Echinococcus granulosus. Therapy with albendazole led to resolution of the pulmonary nodules and a normalization of the white cell count. To our knowledge this is the first described case of acute echinococcosis, as the diagnosis of this disease is usually delayed to chronic phases. Therefore, finding unexplained eosinophilia, especially in association with pulmonary nodules, should lead one to suspect acute hydatid disease.

Volume Measurements

This case report describes a digital workflow used for three main purposes: to predict the volume of particulate grafting material required to perform alveolar ridge preservation; to conduct subsequent virtual implant planning; and to digitally design the respective implant-supported crown. The volume of equine-derived bone grafting material required for filling the alveolar socket is digitally estimated in cubic millimeters from cone beam computed tomographic (CBCT) data using a specific software tool for volume measurements. Digital crown design from an intraoral scan allows for milling the definitive implant-supported crown. For this purpose, a scan body can be used and even slightly trimmed externally to avoid excessive proximity with an adjacent rotated tooth.

Abstract A 17-year-old boy with neurofibromatosis presented with delayed puberty and epileptic seizures of recent onset. A computed tomographic scan revealed aqueductal stenosis due to a tumor of the aqueduct. This tumor was found at autopsy to be a pilocytic astrocytoma. Aqueductal stenosis in neurofibromatosis is uncommon and has been considered to be a result of periaqueductal gliosis. This seems to be the first report of neurofibromatosis associated with a tumor of the aqueduct.

Abstract The authors have treated a 20-year-old man with a dorsal intramedullary epidermoid cyst in whom magnetic resonance imaging was performed both before evacuation of the cyst and 3 months later. Intraspinal epidermoid tumors are rare, and the intramedullary location is quite uncommon. To our knowledge, this is the first description of magnetic resonance imaging of an intramedullary epidermoid cyst. The frequency, possibilities, and limits of surgical treatment of such intraspinal benign tumors are reviewed.
