Spiral-Computertomographie der Mamma

1994

Aim To evaluate the use of spiral CT in the diagnosis of breast lesions. Material and methods 93 female patients with suspicious or uncertain mammographic findings were examined by CT before and after contrast enhancement according to the following practical method: table movement, 6 mm/s, slice thickness 6 mm, increment 4 mm, contrast 200 ml, injection rate 3 ml/s, scan start 50 s after the beginning of the injection. Histological confirmation was present in 85 patients. Results All 44 invasive carcinomas were recognised. They were characterised by intensive focal contrast uptake. Only 2 out of 7 intraductal carcinomas were not shown by CT. 36 out of 38 benign lesions were correctly diagno…

Gegenwärtiger Stellenwert der perkutanentranshepatischen Cholangiodrainage

2002

Percutaneous transhepatic biliary drainage (PTBD) is a well established method in the treatment of obstructive jaundice. Major indications are malignant diseases. PTBD may be necessary preoperatively in cases with severe jaundice or cholangitis or as part of palliative treatment concepts. In the past, it has been proposed that a period of preoperative PTBD may improve the morbidity rates of surgery. Various studies could not prove this theory. The significance of preoperative PTBD has changed, as observed during a 15 years period in our own institution, the indications for preoperative PTBD have decreased by half. At present, the majority of treatments with PTBD are palliative (almost 70 % …

Multiple sclerosis, an unlikely cause of chronic cerebrospinal venous insufficiency: retrospective analysis of catheter venography.

2013

Objectives It is unknown if a relationship exists between multiple sclerosis and chronic cerebrospinal venous insufficiency and if this venous pathology is a causal factor for multiple sclerosis or is a product of a neurological disease. Even so, one should expect that if multiple sclerosis were the cause for venous lesions, then patients with an extended history of the disease would present with a more severe venous pathology. Design Retrospective analysis of catheter venography of the azygous and internal jugularveins, and duration of clinical history of the disease in multiple sclerosis patients. Setting Mono-profile specialist hospital. Participants 353 multiple sclerosis patients, with…

Spontaneous Resorption of an Occipital Meningocele: Computed Tomography and Magnetic Resonance Imaging Evaluation

2016

Cranial meningocele is a very rare variant of encephalocele. Meningocele can be associated with other disorders and may cause complications. Therapy is usually based on surgical treatment. To our knowledge, we describe the first case of spontaneous resorption of an occipital meningocele in a full-term newborn boy. A full-term newborn was noted to have a large non-skin covered, semitransparent cystic lump in the occipital bone. He underwent computed tomography and a diagnosis of meningocele was proposed. After a few hours, the cystic lump spontaneously readsorbed. After 1 week the patient underwent magnetic resonance. Histology confirmed the diagnosis.

Oral Squamous Cell Carcinoma Mimicking Medication-Related Osteonecrosis of the Jaws (MRONJ): A Case Series

2021

(1) Background: Medication-related osteonecrosis of the jaw (MRONJ) is a potential adverse drug reaction of antiresorptive and/or antiangiogenic treatment. MRONJ is mostly diagnosed by anamnestic data, clinical examination and radiological findings, with signs and symptoms often unspecific. On the other hand, oral squamous cell carcinoma (OSCC) is characteristic for its pleomorphic appearance (e.g., ulcer, mucous dehiscence, non-healing post-extractive socket). We report three cases where OSCC mimicked MRONJ lesions. (2) Patients: Three patients undergoing amino-bisphosphonate treatment for osteoporosis presented with areas of intraorally exposed jawbone and unspecific radiological signs co…

Endometrial receptivity: evaluation with ultrasound.

2013

An adequate endometrial receptivity is a crucial factor for embryo implantation. We describe endometrial morphology (endometrial appearance or pattern, endometrial thickness, volume, and delimitation), based on the concepts and possibilities of the new ultrasound modalities (3-dimensional/4-dimensional ultrasound, automatic volume calculation, virtual organ computer-aided analysis, tomographic ultrasound image, inverse mode, and 3-dimensional Doppler angiography) as markers of endometrial receptivity.

PET Lung Ventilation/Perfusion Imaging Using 68Ga Aerosol (Galligas) and 68Ga-Labeled Macroaggregated Albumin

2012

Pulmonary imaging using ventilation/perfusion (V/P) single-photon emission tomography (V/P scan) with Tc-99m-labeled radiotracers is a well-established diagnostic tool for clinically suspected pulmonary embolism (PE). Ga-68 aerosol (Galligas) and Ga-68-labeled macroaggregated albumin (MAA) are potential tracers for positron emission tomography (PET) lung V/P imaging and could display an advantage over conventional V/P scans in terms of sensitivity and specificity. After radiochemical and animal studies, the clinical applicability of Ga-68 aerosol (Galligas) and Ga-68-labeled MAA was investigated in an exploratory study in patients with clinical suspicion of PE. PET scans were acquired using…

Drainage of a Mediastinal Cyst by Endobronchial Ultrasound-Guided Needle Aspiration

Nachsorge des Mammakarzinoms

1994

7865 follow-up examinations were performed on 420 patients who had had surgery for carcinoma of the breast; there were 2755 radiographs of the chest, 2660 sonographic examinations of the upper abdomen and 2450 contralateral mammograms. The most common findings were metastases seen on the chest radiographs during the 13-24 and 25-60 months intervals in 4.7% of cases. The incidence increased with initially higher tumour stages and in ductal carcinomas. Sonography of the upper abdomen showed 4.3% of liver involvement, mostly between the second and fifth year; this was independent of tumour stage or the histology of the primary tumour. Positive mammography of the contralateral breast was found …

Pulmonale Manifestationen bei HIV-Patienten: Rolle von Thoraxübersicht, CT und HRCT

1995

Aim To determine the prevalence of pulmonary changes on chest radiographs and computed tomography (CT/HRCT) in HIV patients and their relation to pulmonary symptoms. Material and method 64 HIV patients were examined prospectively. 15 had no respiratory symptoms (group I), 30 had non-specific respiratory symptoms (group II), 19 complained of dyspnoea (group III). Chest radiographs and CT were performed within a week. In patients with positive findings, bronchoscopy was carried out with bacteriological and histological examinations. Results In group 1, 13% of chest radiographs and 40% of CTs showed infiltrative changes. In group II, the figures were 27% and 57% respectively. In group III, abn…
