We examined the prenatal development of the human anterior cranial fossa and considered its clinical aspects. Our purpose was an evaluation of anterior cranial fossa geometry, its measurements and connections with the nasal cavity and middle cranial fossa. The study was performed on 29 foetuses from the first and second trimester of pregnancy. New methods of computer image analysis, Scion for W...
The majority of anatomical structures within the heart during typical atrial flutters' ablation, right sided accessory pathway ablation or slow pathway ablation are invisible or blurred. Therefore it is very important to know in details interior right atrial structures during such procedures. In the neighborhood of coronary sinus orifice small concavity is visible. This area, called subthebesia...
Germ cell tumors comprise approximately 2-5% of all childhood brain tumors. They arise predominantly in the pineal and suprasellar region, but may occur throughout the brain. Teratomas are generally divided into gonadal and extragonadal types. A posterior fossa teratoma is a rare occurrence. The focus of this discussion is a 5-year-old boy with posterior fossa teratoma who recovered completely ...
A 70-year-old man presented for evaluation of recurrent urinary tract infection. He had history of hypertension and had undergone suprapubic prostatectomy 8 years ago for enlarged obstructive prostate. Digital rectal examination found a stony irregular prostate and urine culture grew Escherichia Coli that was susceptible to Cephalosporines. As part of the evaluation, a plain radiograph was perf...
It is well known that head injuries with a linear skull fracture in infancy sometimes cause a growing skull fracture') with or with out a leptomeningeal cyst.') This condition, however, is mainly located in the supratentorial portion of the cranium. Leptomeningeal cysts in the posterior fossa are rare, and to our knowledge, there have been only four cases reported in the literature. The leptome...
A series of 6 patients with arachnoid cysts of the posterior fossa who were treated surgically is presented. The diagnosis of the nature of the lesion and of the exact location within the posterior fossa could not be established on a clinical basis. CT scanning is the best method for diagnosing the lesion and for observing the postoperative evolution. Treatment consisted of removing the cyst wa...
Dystrophic calcifications have been detected in the prostatic fossa, especially after de-obstructing procedures or radiotherapy for prostate cancer. These calcifications can be recalcitrant in patients with poor tissue healing. Hyperbaric Oxygen (HBO) therapy has multiple applications in urology but has not been reported as a treatment of recalcitrant dystrophic calcifications of the prostatic ...
INTRODUCTION Traditionally, the prone position is used for dissecting the popliteal fossa, which requires endotracheal intubation. Access to the airway in this position is limited, hence the complications. It is not surprising that the prone position is not favoured by the anaesthetists, especially in patients with a high body mass index. We describe a safe and novel alternative to the prone po...
We prospectively analyzed the learning process for transseptal catheterization guided by intracardiac echocardiography, in 50 patients who underwent radiofrequency ablation for left atrial arrhythmias. In 20 patients the intracardiac echocardiography catheter was positioned in the right atrium to visualize the fossa ovalis and the tenting of the fossa caused by the Brockenbrough needle. In the ...
PURPOSE Our purpose was to determine the neuroradiologic findings of Marinesco-Sjögren syndrome on plain skull radiographs, CT, and MR images. METHODS Eight patients with proved Marinesco-Sjögren syndrome (age range, 4 to 56 years) had a total of nine CT scans, seven MR imaging studies, and two plain radiographic examinations of the skull. The findings were reviewed retrospectively, with part...
