Evaluation of temporal bone computed tomography and paranasal sinuses magnetic resonance images in acromegalic patients.

Objective: Acromegaly is a rare disease, which symptoms are caused by excess secretion of a growth hormone (GH) from the anterior pituitary benign tumor - adenoma. Authors present an evaluation of computed tomography (CT) and magnetic resonance (MR) images of temporal bone and paranasal sinuses of patients with acromegaly.

Conclusions: 1.

MRI image characteristics of materials implanted at sellar region after transsphenoidal resection of pituitary tumours.

Background: Post-surgical evaluation of the pituitary gland in MRI is difficult because of a change in anatomical conditions. It depends also on numerous other factors, including: size and expansion of the tumour before surgery, type of surgical access, quality and volume of implanted materials and time of its resorption. The purpose was to demonstrate the characteristics of the implanted materials on MRI performed after transsphenoidal resection of pituitary tumours and to identify imaging criteria helpful in differential diagnosis of masses within the sellar region.

Late presenting diaphragmatic hernia: clinical and diagnostic aspects.

Background: The congenital diaphragm hernia presents most frequently in the neonatal period. In a small group of children his defect can be diagnosed beyond the newborn age, during late infancy or early childhood. The late presenting congenital diaphragm hernia is characterized by a variable clinical picture and represents a considerable diagnostic challenge.

[The usefulness of contrast-enhanced sonography in the differential diagnostic of adrenal tumors].

Introduction: The occurrence of gland tumors causes significant clinical problem. Non hormone-secreting tumors provide the most complicated diagnostic difficulties. The application of contrast-enhanced sonography could improve the vessels visualization and point out characteristic features of benign and malignant changes.

[Usefulness of imaging in the diagnosis of salivary gland diseases].

Unlabelled: The aim of this study was to evaluate the value of modern imaging modalities in the diagnosis and management of different salivary gland diseases.

Material And Methods: Material comprised of 135 patients (79 women and 56 men) at the age 14-70 (mean aged 35, 7). Ultrasonography (US) was basic examination in every case.

Femoral and iliac vein stenoses after prolonged femoral vein catheter insertion.

Background/aims: Catheterization of the femoral vein is a safe and recommended method of temporary access for haemodialysis. In some patients, however, because of the lack of other possibilities, it is necessary to maintain long-term femoral cannulation. The aim of the study was to evaluate the frequency of stenosis after prolonged femoral cannulation.
