[MRI-based diagnosis of an acute bilateral compartment syndrome]

The acute compartment syndrome describes a posttraumatic or inflammatory edema, which leads to a painful constraint of muscular movement and paresthesia. An increase in pressure in the anatomical compartment is postulated. The main symptoms include local swelling, sensory loss, local muscle weakness as well as late livid discoloration. Therapy of choice is an early fasciotomy with decompression to avoid serious complications like muscle necrosis. Here we report a 22 year old patient who postoperatively suffered from a bilateral paresis of the foot jack. Further examinations by electromyography and magnetic resonance imaging (MRI) led to the diagnosis of an acute bilateral compartment syndrome

[Pneumatosis cystoides intestinalis: a rare illness in adults]

Pneumatosis cystoides intestinalis (PCI) is a rare illness in adults with gas filled blebs found in the submucosa or subserosa of the bowel wall. The main localization is the terminal ileum although all parts of the intestine can be affected. Clinical symptoms can vary from aqueous-slimy, bloody diarrhea to constipation and/or vague abdominal pain. Patients can also be completely asymptomatic. In symptomatic patients the therapy of PI is based on the assumed pathogenesis, so that a combined treatment of metronidazole 1500 mg daily during a period of 6-8 weeks additionally and oxygen application (PaO2 of 200-350 mmHg) for 7 days is suggested. In addition, elemental diets are recommended. Complications are indicated in the literature with 3%. In particular mechanical ileus, invagination and perforation as well as substantial intestinal bleeding up to the volvolus lead to further diagnostic and therapeutic steps. A surgical intervention is reserved for rare cases

[MRI-based diagnosis of giant cell arteritis]

The giant cell arteritis and its symptoms are usually non-specific and accompanied with symptoms of polymyalgia rheumatica. As complications of the giant cell arteritis ischemia, infarction or rupture of the damaged vessel can occur. We report on a 56-year-old female patient, who suffered for one year about weight loss, tiredness and intolerance as well as symptoms of polymyalgia rheumatica. Gastroscopy and colonoscopy showed normal findings. In the context of the malignancy search we made a computer tomography and magnet resonance tomography. The data showed an enlargement and an enhancement of the aorta, which led us to the suspicion of a giant cell arteritis. We started immediately with a medical treatment. The biopsy of the arteries temporales supported histological the diagnosis

Should 3K zoom function be used for detection of pneumothorax in cesium iodide/amorphous silicon flat-panel detector radiographs presented on 1K-matrix soft copies?

The purpose of the study was to evaluate observer performance in the detection of pneumothorax with cesium iodide and amorphous silicon flat-panel detector radiography (CsI/a-Si FDR) presented as 1K and 3K soft-copy images. Forty patients with and 40 patients without pneumothorax diagnosed on previous and subsequent digital storage phosphor radiography (SPR, gold standard) had follow-up chest radiographs with CsI/a-Si FDR. Four observers confirmed or excluded the diagnosis of pneumothorax according to a five-point scale first on the 1K soft-copy image and then with help of 3K zoom function (1K monitor). Receiver operating characteristic (ROC) analysis was performed for each modality (1K and 3K). The area under the curve (AUC) values for each observer were 0.7815, 0.7779, 0.7946 and 0.7066 with 1K-matrix soft copies and 0.8123, 0.7997, 0.8078 and 0.7522 with 3K zoom. Overall detection of pneumothorax was better with 3K zoom. Differences between the two display methods were not statistically significant in 3 of 4 observers (p-values between 0.13 and 0.44; observer 4: p = 0.02). The detection of pneumothorax with 3K zoom is better than with 1K soft copy but not at a statistically significant level. Differences between both display methods may be subtle. Still, our results indicate that 3K zoom should be employed in clinical practice

TAP deficiency syndrome: chronic rhinosinusitis and conductive hearing loss

Nose-ear-throat manifestations of immunodeficiency disorders represent a diagnostic challenge for clinicians as these diseases often constitute the initial sign for connective disorders or autoimmune disease. The history of chronic rhinosinusitis and conductive hearing loss is often non specific. Therefore attention to an HLA class I deficiency must be considered if the disease has not been diagnosed on routine examination. One of the syndromes is due to a defective TAP complex, the peptide transporter complex associated with antigen presentation. Herein, we report two sisters with TAP-deficiency. The treatment of choice for TAP-deficient patients is conservative
