Elastofibroma dorsi: typical radiological features.

Elastofibroma dorsi is a rare benign and slow-growing fibro-proliferative lesion. It has a characteristic location (periscapular region) and a specific imaging appearance (sonography, CT, MRI) allowing accurate prospective diagnosis. The recognition of this benign lesion avoids unnecessary biopsy and/or surgery.

Detection of colonic masses with MR colonography.

Background/aims: Magnetic resonance colonography based on magnetic resonance imaging is a relatively new diagnostic modality for diagnosing colon pathology. The aim of this study was to evaluate its performance in detecting colorectal masses.

Methods: Thirty-three patients (20 male, 13 female; age range 28-85 years; mean age 78.

Characterization of focal liver lesions: use of mangafodipir trisodium (MnDPDP)-enhanced MR images.

Background/aims: We evaluated the characterization and detection of liver lesions using mangafodipir trisodium.

Methods: A total of 51 patients with liver lesions [13 hepatocellular carcinomas, 18 metastases, 14 hemangiomas, three cholangiocellular carcinomas, two hydatic cysts, and one focal nodular hyperplasia (FNH)] were examined by unenhanced and mangafodipir trisodium-enhanced MRI.

Results: After administration of mangafodipir trisodium by slow intravenous infusion, mangafodipir trisodium-enhanced MRI was performed at 15-30 min and 24 h.

Experimental evaluation of the effects of zoledronic acid on regenerate bone formation and osteoporosis in mandibular distraction osteogenesis.

Purpose: The aim of this study was to evaluate the effects of systemically administered zoledronic acid (ZA) on the bone mineral density (BMD) and bone mineral content (BMC) at mandibular distraction sites in rabbits.

Materials And Methods: Eighteen New Zealand white rabbits were randomly divided into 2 groups. Bone lengthening was performed in the left portion of the mandible through distraction osteogenesis at a rate of 0.

Three-dimensional MR and axial CT colonography versus conventional colonoscopy for detection of colon pathologies.

Aim: To evaluate the sensitivity and specificity of MR colonography (MRC) and CT performance in detecting colon lesions, and to compare their sensitivity and specificity with that of conventional colonoscopy.

Methods: Forty-two patients suspected of having colonic lesions, because of rectal bleeding, positive fecal occult blood test results or altered bowel habits, underwent the examinations. After insertion of a rectal tube, the colon was filled with 1000-1500 mL of a mixture of 9 g/L NaCl solution, 15-20 mL of 0.

Mangafodipir trisodium-enhanced magnetic resonance imaging for evaluation of pancreatic mass and mass-like lesions.

Aim: To investigate the role of mangafodipir trisodium (MnDPDP) in focal pancreatic masses and mass-like lesions by evaluating contrast uptake features of the lesions and pancreatic parenchyma after contrast medium injection.

Methods: A total of 37 patients with pancreatic mass or mass-like lesions were examined by unenhanced and MnDPDP-enhanced magnetic resonance imaging (MRI).

Results: MRI was obtained 20-40 min after infusion of MnDPDP and homogeneous contrast enhancement was observed in normal pancreas parenchyma.

Spontaneous rupture of choledochal cyst presenting in childhood.

Spontaneous rupture of choledochal cysts is one of the rare complications, and can sometimes be the initial manifestation. It should be considered in the presence of bile-like fluid. A 10-year-old girl had acute onset of abdominal pain, vomiting, and elevated bilirubin, alkaline phosphatase, glutamic oxaloacetic transaminase and glutamic-pyruvic transaminase levels.

Distal femur morphometry: a gender and bilateral comparative study using magnetic resonance imaging.

Among the anthropometric factors to be considered, anatomic differences in the distal femur and intercondylar notch have been implicated as a cause of the different rates of anterior cruciate ligament (ACL) rupture between men and women; therefore, in this study our aim was to evaluate a number of morphometric measurements in the distal part of the femur. Two hundred knee MRI examinations were analyzed: 56 male right, 44 male left, 42 female right and 58 female left. Measurements of the intercondylar height (ICH), intercondylar width (ICW), medial condylar width (MCW), lateral condylar width (LCW) and epicondylar width (EW) were obtained.

Diagnostic value of diuretic-enhanced excretory MR urography in patients with obstructive uropathy.

Purpose: Ultrasonography and conventional intravenous urography are most common methods in diagnosis of obstructive uropathies. The disadvantage of ultrasonography is inability of visualizing middle and lower one thirds of ureter, while intravenous urography is using radiation, also functionally extra loading effect on kidneys. In this study, the diagnostic value of MR urography on obstructive uropathy were investigated.

Mesenteric ischemia: an unusual presentation of fistula between superior mesenteric artery and common hepatic artery.

Chronic mesenteric ischemia is an uncommon condition associated with a high morbidity and mortality. We reported a 36-year old women with postprandial abdominal pain due to chronic mesenteric ischemia caused by a fistula between superior mesenteric and common hepatic artery.

[Plexiform neurofibroma in the gingiva].

Neurofibromatosis type 1 is the most common autosomal dominant disorder of the nerve sheath and best defined phakomatosis. It usually affects skeletal system, central nervous system, eye, endocrine gland and cardiovascular system. Gingival involvement is very rare.

Post-traumatic arteriovenous fistula presented with hypertrophic palmaris digitalis II.

A 19-year-old female was admitted to our department because of a hypertrophic palmaris digitalis II of the left hand displaying color changes. A thrill was easily palpated over the medial part of the finger. A review of her history revealed that this hypertrophy occurred after a blunt trauma to the left hand.

Uncommon locations of hydatid cysts.

Hydatid disease is endemic in many parts of the world. It may develop in almost any part of the body. The location is mostly hepatic (75%) and pulmonary (15%), and only 10% occur in the rest of the body.

The role of hyperbaric oxygen in the management of subarachnoid hemorrhage.

Objective: To determine the role of hyperoxic and hyperbaric therapy following experimental subarachnoid hemorrhage (SAH).

Design: Prospective, randomized, controlled animal study.

Subjects: Thirty male Wistar rats.

Omental transposition decreases ischemic brain damage examined in a new ischemia model.

Purpose: The aim of this study was to determine whether omental transposition at the time of focal cerebral ischemia can decrease ischemic brain damage produced in dogs, in a new ischemia model, which had been described by us.

Methods: In group 1 (n = 5), the left internal carotid artery and arterial circle of the brain (posterior communicating artery in humans) were occluded permanently. In group 2 (n = 5), additionally to this ischemia model, omental transposition was performed simultaneously.

Contrast media-enhanced power Doppler sonography for evaluation of hemangiomas and malignant tumors in the liver.

Aim: To evaluate the characterization of liver hemangiomas and malignant tumors using power Doppler sonography before and after intravenous injection of a sonocontrast agent.

Methods: Forty-five patients with 57 liver tumors (22 hemangiomas, 24 metastases, 10 hepatocellular carcinomas (HCC) and one cholangiocellular carcinoma) were examined prospectively. The distribution (peripheral, central, mosaic) and extent (none, minimal, moderate and strong) of intratumoral flow pattern in each sonographic examination was subjectively classified.

Bilateral common carotid occlusion without neurological deficit.

A 40-year-old man presented with pain and numbness in his right arm. On his clinical examination, no neurological deficit was found. Bilateral common carotid artery duplex sonography scan demonstrated no flow in either lumen.

Fluoroscopy-guided intraarticular corticosteroid injection into the sacroiliac joints in patients with ankylosing spondylitis.

Purpose: Our goal was to prospectively study the therapeutic efficacy of CT-marking and fluoroscopy-guided intraarticular corticosteroid instillation of inflamed sacroiliac joints in patients with ankylosing spondylitis.

Material And Methods: A total of 22 fluoroscopy-guided intraarticular corticosteroid injections in the sacroiliac joints were performed in 17 patients with ankylosing spondylitis and severe low back pain. Needle puncture point, angle of intervention and distance of sacroiliac joint from the skin were determined by sacroiliac joint axial CT examination in prone position.
