Recurrent vertebral hydatid disease: spectrum of MR imaging features.

Introduction: This study aimed to describe a spectrum of magnetic resonance (MR) imaging findings in a case series of four patients with recurrent vertebral hydatid disease (HD).

Methods: Four patients with recurrent spinal HD, who were studied with MR imaging at 1.5T or 0.

Acute segmental intestinal ischemia: diagnosis with spiral computed tomography.

The purpose of this study was to examine the usefulness and the validity of spiral computerized tomography (CT) in assessing acute segmental intestinal ischemia. We present the spiral CT imaging findings in surgically proven cases of intestinal ischemia. 46 patients were admitted to our facility over a five-year period with suspicion of acute enteric ischemia.

Traumatic retropharyngeal hematoma and prevertebral edema induced by whiplash injury.

Whiplash injury commonly results in cervical spine trauma. We report a case of a 58-year-old man, who sustained a whiplash injury from contact with the headrest of his seat after his car was involved in a rear-end collision. He presented with sore throat, hoarseness, difficulty in swallowing and progressing dyspnea.

Contrast-enhanced spiral CT evaluation of blunt abdominal trauma.

The purpose of this study was to examine the usefulness and validity of contrast enhanced-spiral computerized tomography in assessing blunt abdominal trauma. 257 patients were admitted in a general hospital over a period of five years and were examined with computed tomography. Two-dimension reconstruction and delayed imaging were used when appropriate.

MR imaging of tuberculous vertebral osteomyelitis: pictorial review.

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 vertebral body, epidural involvement, and paraspinal abscess are the most common MRI findings suggestive of tuberculous vertebral osteomyelitis.

Cognitive function in non-demented individuals complaining of short-term memory disturbances: a study with event-related potentials (P 300) and brain CT scan.

Event-related potentials (ERPs) were elicited in 30, non-consecutive, non-demented individuals, complaining of short-term memory disturbances. Fifteen of them had a moderate diffuse cerebral atrophy on their brain CT and the other 15 had a negative brain CT. ERPs were also elicited in 15 age-matched controls with no reported memory disturbances and negative brain CTs.

MRI of nasopharyngeal carcinoma metastatic to the cerebellopontine angle.

In patients with nasopharyngeal carcinoma, intracranial spread may occur via direct extension from the base of the skull or via perineural spread. Perineural spread usually affects branches of the trigeminal nerve. We describe two patients with recurrent nasopharyngeal carcinoma, who presented with a solitary mass in the cerebellopontine angle without associated bony destruction.

Evaluation of hydatid disease of the heart with magnetic resonance imaging.

Two patients with cardiac involvement of hydatid disease are presented: one with hydatid cyst of the interventricular septum and pulmonary arteries and the other with multiple pulmonary cysts associated with intracardiac and pericardial cysts. The ability of magnetic resonance imaging (MRI) to provide a global view of cardiac anatomy in any plane with high contrast between flowing blood and soft tissue ensures it an important role in the diagnosis and preoperative assessment of hydatid disease of the heart.

MRI features in a malignant glomus jugulare tumour.

Magnetic resonance imaging (MRI) features in a case of malignant glomus jugulare tumour are reported. Chemodectomas are benign in 95 per cent of cases and malignant in five per cent. Only one case report of CT findings in this unusual CP angle tumour with pulmonary metastases has been cited in the literature.
