Abstract A 54-year-old lady presented with a mass in the left atrium causing an acute mitral valve pseudo-stenosis. The tumour mass was assumed to be a myxoma. The patient was scheduled for tumour ...mass extirpation to clear the obstruction of the mitral orifice. Histological finding from the acquired specimen showed a leiomyosarcoma, as a rare primary malignant cardiac tumour.
The aim of this study was to assess effectiveness, stability, position, and expansibility of an expansible aortic annuloplasty ring with computed tomography (CT).
Ten men (median age 51 years) ...scheduled for aortic root remodeling with implantation of external annuloplasty ring underwent contrast-enhanced CT of the aortic root preoperatively, postoperatively, and at a median of 21 months after operation. A reconstructed transverse double oblique view of the aortic base (AB) and of the new defined annuloplasty ring base (ARB; plane of the lower edge of the ring) in systole and diastole were obtained. The diameters, perimeter, and area were measured. In addition, the distances between AB and ARB in the nadir of each sinus were measured.
We found 12% reduction of the postoperative AB and 19% of ARB perimeter in both systole (p = 0.004, p < 0.001, respectively) and diastole (p = 0.001, p < 0.001, respectively) compared with preoperative. There was 22% reduction of the postoperative AB area in systole and 24% in diastole (p = 0.002, p = 0.001, respectively) and 33% reduction of the ARB area in systole and 32% in diastole (p < 0.001 for both) compared with the preoperative period. Nearly all measured variables in the follow-up period showed a slight increase compared with the postoperative period; however, they did not reach statistical significance. The postoperative systolic-diastolic differences in the three measured variables at the level of AB and ARB were statistically significant and were maintained throughout the follow-up period. The base of the ring was implanted 2 ± 2 mm at the right, 0 ± 1 mm at the left above the AB, and 2 (-3 to 2) mm at the noncoronary nadir below the AB.
This study demonstrates imaging evidence of the effectiveness, stability, and pulsatility of the annuloplasty ring in aortic root remodeling in follow-up and describes the exact position of the ring at the base of the aortic root.
To investigate whether the use of magnetic resonance imaging (MRI) in prostate bed treatment planning could influence definition of the clinical target volume (CTV) and organs at risk.
A total of 21 ...consecutive patients referred for prostate bed radiotherapy were included in the present retrospective study. The CTV was delineated according to the European Organization for Research and Treatment of Cancer recommendations on computed tomography (CT) and T(1)-weighted (T(1)w) and T(2)-weighted (T(2)w) MRI. The CTV magnitude, agreement, and spatial differences were evaluated on the planning CT scan after registration with the MRI scans.
The CTV was significantly reduced on the T(1)w and T(2)w MRI scans (13% and 9%, respectively) compared with the CT scans. The urinary bladder was drawn smaller on the CT scans and the rectum was smaller on the MRI scans. On T(1)w MRI, the rectum and urinary bladder were delineated larger than on T(2)w MRI. Minimal agreement was observed between the CT and T(2)w images. The main spatial differences were measured in the superior and superolateral directions in which the CTV on the MRI scans was 1.8-2.9 mm smaller. In the posterior and inferior border, no difference was seen between the CT and T(1)w MRI scans. On the T(2)w MRI scans, the CTV was larger in these directions (by 1.3 and 1.7 mm, respectively).
The use of MRI in postprostatectomy radiotherapy planning resulted in a reduction of the CTV. The main differences were found in the superior part of the prostate bed. We believe T(2)w MRI enables more precise definition of prostate bed CTV than conventional planning CT.
Use of the prenatal MRI in the orofacial cleft diagnostics Aim: To evaluate the accuracy and credibility of MRI in the assessment of the fetal facial cleft lip defects severity using interobserver ...agreement between several specialists. Material and method: Our study consists of 23 MRI examinations of fetuses in gestation age before 24 week with differently severe lip clefts, which was detected by ultrasound as well as other 17 examinations without face anomaly (40 cases in total). Datasets were anonymized and analyzed by 3 radiologists and statistical analysis was performed. According to standardised protocol presence of cleft and degree of severity was evaluated - alveolar ridge involvement, continuation or noncontinuation to the pallate. The examinations were perfomed by Siemens Magnetom Symfony Masestro Class 1,5T with use of array coils. Results: Result of MRI was in 20 cases (87 %) in agreement with clinical findings. We found 3 discrepancies (13 %), mainly due to graphically limited examination caused by fetal movements. The best degree of interpretative agreement was in the evaluation of alveolar ridge involvement - 94 % (generalized kappa 0,894, SE 0,106), for isolated cleft lip it was 90 % (generalized kappa 0,848, SE 0,083) and for defect of palatte 86 % (generalized kappa 0,711, SE...
Uvedena kazuistika pětiletého chlapce s týden trvajícími bolestmi a výtokem z pravého ucha. Obtíže přetrvávaly i přes nasazenou antibiotickou léčbu. Otoskopický nález odpovídal polypózní mase ...obturující zevní zvukovod se sanguinolentní sekrecí. Chlapci bylo provedeno vyšetření hlavy počítačovou tomografií s vysokým rozlišením (HRCT) a magnetickou rezonancí (MR) s nálezem měkkotkáňové masy, vyplňující zevní zvukovod, středoušní dutinu a pneumatický systém mastoidního výběžku a s rozsáhlou destrukcí skeletu v oblasti mesotympana, protympana, hrotu pyramidy a stěny karotického kanálu vpravo. Konečnou diagnózu rhabdomyosarkomu stanovilo histologické vyšetření vzorku odebraného z polypózní masy ze zevního zvukovodu. Cílem sdělení je upozornit na možnost málo časté, ale závažné příčiny sekrece z ucha.
We report a case of 5-year-old boy with a week lasting pain and a discharge of the right ear. Symptoms persisted without improvement despite antibiotic treatment. The otoscopic finding seemed to be a polyp mass obturing an external auditory canal and was accompained with a sanguinolent discharge. The boy's head was examined by high resolution computer tomography (HRCT) and magnetic resonance imaging (MRI) with finding of soft tissue mass filling the external auditory canal, a middle ear, mastoid and its air cell system and large bone destruction in the area of the mesotympanum, protympa-num, apex of pyramid and carotic canal on the right side. The final diagnosis of rhabdomyosarcoma was set down by histological examination of a sample obtained from polyp mass in external auditory canal. The aim of this article is to call attention to a possibility of rare but serious cause of the ear discharge.

Ve třech kazuistikách je demonstrován dnešní pohled na diagnostiku a léčbu nitrolebních komplikací vznikajících v průběhu akutního či chronického středoušního zánětu. Jde o závažná onemocnění, která ...vyžadují přesnou diagnózu a rychle nasazenou odpovídající terapii. Mezi nitrolební zánětlivé otogenní komplikace patří: ohraničená pachymeningitida, periflebitida esovitého splavu, epidurální a perisinuózní absces, trombóza a tromboflebitida nitrolebních splavů, difuzní hnisavý zánět mozkových obalů, subdurální empyém, mozkový a mozečkový absces. Základní úlohu v diagnostice nitrolebních otogenních zánětlivých komplikací hrají zobrazovací metody, hlavně počítačová tomografie (CT) a magnetická rezonance (MR). Léčba nitrolebních otogenních komplikací je založena na podávání antibiotik a chirurgické sanaci zánětu spánkové kosti.
In these three case reports is demonstrated today's perspective on the diagnosis and treatment of intracranial complications arising during an acute or chronic otitis media. These are serious diseases, that require the accurate diagnosis and rapid deployment of appropriate therapy. Among the intracranial complications are included the bordered otogenic inflammatory pachymeningitis, sigmoid sinus periflebititis, epidural and perisunusoidal abscess, thrombosis and thrombophlebitis of intracranial sinuses, diffuse suppurative inflammation of the brain round, subdural empyema, brain and cerebellar abscess. The basic role in the diagnosis of otogenic inflammatory intracranial complications plays the imaging , especially computed tomography (CT) and magnetic resonance imaging (MRI).The treatment of otogenic intracranial complications is based on the use of antibiotics and surgical rehabilitation of the temporal bone inflammation.
