[Virtual colonography in CT and MRI examinations].

The paper presents new ways of visualizing internal structures of the large intestine. Use of spiral computed tomography (CT) or magnetic resonance imaging (MRI) combined with appropriate software leads to imaging that can be compared with colonoscopy or double contrast enema. The authors discuss patients' preparation, methods for CT and MRI variants, indications, advantages and costs.

Extracolonic findings at CT colonography - additional advantage of the method.

BACKGROUND: In virtual colonoscopy (VC) we are capable to assess all organs located between a diaphragm and pelvic bottom. This report provides a breakdown of extracolonic pathological findings in VC performed in standard indications. MATERIAL/METHODS: We reviewed 71 consecutive VC (29 men and 42 women) performed using double-slice scanner General Electric High Speed NX/I Pro. Pathological findings were presented in a tabular form illustrated by sample images. RESULTS: Extracolonic findings were found in 53 cases (74.6%), and were equally frequent in subgroups with pathological colon and free from colon lesions. Renal cysts occurred most often. In 15 cases the extracolonic pathologies were clinically important, most of them tumors. CONCLUSIONS: VC is found to be a very useful tool in the detection and evaluation of extracolonic pathologies.

[Myositis ossifications progressiva].

Myositis ossificans progressiva (MOP) is a rare hereditary connective tissue disorder. Skeletal abnormalities and progressive ectopic ossifications are features of this condition. Diagnosis is often delayed because of heterogenous picture of MOP. Treatment is unknown, so MOP leads to prolonged disability.

[Melkersson-Rosenthal syndrome as a rare cause of recurrent facial nerve palsy].

Melkersson-Rosenthal syndrome is a rare cause of recurrent facial nerve palsy. The syndrome is classically characterized by a triad of signs consisting of facial edema, recurrent peripheral facial nerve paralysis, and congenital fissured tongue, although it may also present in a mono- or oligosymptomatic form. The paper presents a 24-year-old woman with right-sided peripheral facial nerve palsy and a history of left-sided episodes of facial nerve palsy. Magnetic resonance angiography of the cerebral vessels suggested compression of the right seventh and eighth cranial nerves by a vascular loop. The authors describe the patient with a complete picture of Melkersson-Rosenthal syndrome and discuss the diagnosing process and treatment.

[Role of perfusion imaging in computed tomography in diagnostics of cerebral gliomas].

CT perfusion is a new diagnostic method which enables imaging of the hemodynamics of tissues and organs. Until now most of the publications have been focused on the use of this technique to assess acute stroke. The aim of the presented work is to show the role of CT perfusion in the diagnosis of cerebral gliomas. These tumors are characterized by intensive vascularity which results in an increased blood volume (CBV), blood flow (CBF) and permeability surface (PS) values in perfusion CT examination. A correlation has been reported between perfusion parameters and the histopathological tumor grade. CT perfusion provides morphological and functional information which is useful in the diagnosis, planning treatment strategies and monitoring of the therapeutic effect in cerebral gliomas.
