A migrated sewing needle to the liver.
No full textA 52-year-old woman was investigated for right upper quadrant abdominal pain. Abdominal X-ray revealed a linear metallic object superposed to the liver (Fig. A, arrow). Patient’s history was irrelevant except for a breast biopsy 20 years previously. She did not report any blunt abdominal trauma. Unenhanced abdominal CT was performed for exact localization of the foreign body. A linear metallic opacity was observed in the medial segment of left liver lobe (Fig. B). At laparotomy, a needle was found in the parenchyma over the hilar plate of the liver. Its location was checked by intraoperative fluoroscopy then it was extracted with a clamp through a small incision in the liver parenchyma. High resolution X-ray graph revealed that the foreign body was a sewing needle (Fig. C). At eight months follow up, she is symptom free without any complication
Value of contrast-enhanced magnetic resonance cholangiography in patients undergoing laparoscopic cholecystectomy
No full textLaparoscopic cholecystectomy (LC) is the preferred treatment for symptomatic gallstone disease. Biliary injury during LC is still a serious problem. Knowledge of anatomic detail is important for not encountering the injury. Magnetic resonance cholangiography (MRC) is a noninvasive method for imaging the biliary ducts. However, MRC has many drawbacks such as not showing anatomic structures in detail and respiratory motion. In this study, contrast-enhanced MRC was used to show cystic ducts that are not seen on MRC. Reasons for patient referral for MRC and contrast-enhanced MRC included suspicion of cholecystolithiasis, adenomyomatosis, and gallbladder polyp. Our results show that routine MRC revealed cystic ducts in 38 patients (77.5%) and contrast-enhanced MRC in 46 patients (93.8%). Intraoperative cholangiography (IOC) was taken as gold standard for all patients. We found that contrast-enhanced MRC can provide a useful supplement to MRC in patients with cystic ducts not seen on MRC. To our knowledge, this is the first study of visualization of a cystic duct in patients undergoing LC depicted by both MRC and contrast-enhanced MRC
Diffuse pneumocephalus associated with infratentorial and supratentorial hemorrhages as a complication of spinal surgery
No full textA 23-year-old woman was transferred to our department with loss of consciousness 6 h after undergoing rod placement for thoracolumbar scoliosis. Both computed tomography and magnetic resonance imaging of the brain revealed diffuse pneumocephalus and infra- and supratentorial hemorrhages. The pedicular screw tracts were analyzed with computed tomography and misplacement of a screw was noticed. It was thought that inadvertent dural injury had occurred at the time of insertion. The patient was reoperated and the dural tear was repaired. To our knowledge, this is the first description of these uncommon complications in one patient after spine surgery
Retroaortic left renal vein: Multidetector computed tomography angiography findings and its clinical importance
No full textPurpose: To evaluate the appearance, type, frequency, and clinical importance of retroaortic left renal vein (RLRV) in patients examined with multidetector computed tomography (MDCT) angiography
Unusual Mass-Like Appearance of Tuberculous Osteomyelitis
No full textA 33-year-old woman with chronic tuberculosis was referred to our service with swelling and pain at her right elbow. A lytic lesion in the right distal humerus was found on radiographic examination. Magnetic resonance imaging (MRI) was performed with suspicion of a lytic tumor, and there was a hypointense lytic mass on T1-weighted images with soft tissue involvement and mild enhancement after contrast administration. Anterior and lateral bone scans with Tc-99m methylene diphosphonate (MDP) revealed increased uptake in only the right distal humerus. The diagnosis was caseous granulomatous osteomyelitis obtained by pathologic examination of the biopsy from the lesion
Computed tomography findings in diseases of the adrenal gland
No full textThe adrenal gland is a common site of disease, with an abnormality prevalence as high as 9% in autopsy series. With the increasing use of CT, adrenal lesions are frequently found in the daily practice of radiology and are diagnosed in up to 5% of CT examinations performed for varied reasons. Imaging features on CT can establish a specific diagnosis of many of these lesions, including myelolipoma, hematoma and cysts. Once a diagnostic dilemma, now adenomas can be accurately diagnosed using unenhanced CT, chemical shift magnetic resonance imaging and CT contrast washout analysis. Because the adrenal gland is also a frequent site of metastasis, recent literature has focused on imaging characterization of adrenal masses for differentiation of adenomas from metastases. In patients without known malignancy, most adrenal lesions are benign and a specific diagnosis can now be made on the basis of imaging features
