Vertebral osteomyelitis is one of the most common manifestations of tuberculosis. Magnetic resonance imaging is considered the main imaging modality for the diagnosis, the demonstration of the extent of the disease, and follow-up studies. Vertebral destruction involving two consecutive levels with sparing of the intervertebral disc, disc herniation into the(More)
Focal nodular hyperplasia is an uncommon benign hepatic tumor that continues to pose diagnostic dilemmas. Imaging techniques are of great value in diagnosis of this tumor. In this article we present the US, CT, MR imaging, scintigraphy, and angiography findings. The demonstration of a central vascular scar is very helpful. Although the radiologic features(More)
A 33-year-old female patient was investigated for a right lower quadrant pain. The investigation, which included an excretory urography and a computed tomography examination, revealed a normal kidney on the right side and another two normal sized, complete kidneys on the left side, which appeared to have a small parenchymal bridge. The patient was treated(More)
Localisation of spinal cord lesions by MRI was correlated with neurological symptoms and signs in 16 patients with clinical and laboratory evidence of multiple sclerosis. There was good correspondence between spinal cord lesions and motor tract signs. On the other hand, superficial or deep sensory disturbances correlated with spinal cord lesions in only(More)
Five cases of tumour-like extramedullary haemopoiesis (EH) causing spinal cord compression or back pain are reported. Three patients were suffering from thalassaemia major, one from sickle cell anaemia and one from thalassaemia intermedia. CT findings included soft tissue masses in the epidural space of the spinal canal, spinal cord displacement and(More)
A 54-year-old man first was admitted with a right oculomotor nerve palsy that ameliorated spontaneously. Two months later, he was readmitted with right proptosis, ophthalmoplegia, and optic nerve involvement. MR showed an enlarged right cavernous sinus. There was dramatic improvement after high doses of steroids. MR findings 10 months later were normal.(More)
Magnetic Resonance (MR) imaging features of pineal region tumors were analyzed in 14 oncologic cases. The tumors were classified as germ-cell tumors, glial tumors, pineal parenchymal tumors, meningiomas, and cysts. They demonstrated different MR signal characteristics on precontrast scans and nodular or ring type enhancement with occasional central(More)
A case of extramedullary hemopoiesis in an 18-yr-old girl suffering from beta-thalassemia is reported. Extramedullary hemopoietic masses were localized apart from the paraspinal region in the retrocrural areas as well as the presacral region associated with massive destruction of the sacrum. The importance of recognition of hemopoietic masses in these(More)
The role of cerebral and spinal cord MRI was investigated in 65 patients with myelopathy suspected of having demyelinating disease. Cerebral MRI demonstrated lesions compatible with demyelination in 80% and spinal cord MRI in 68.6%. In 28.5% of our patients brain lesions were present with normal spinal cord images, but in 17% spinal cord lesions were(More)
