    Notes: Abstract Gastrobronchial fistula is a rare complication of antireflux surgery, whereas esophagobronchial fistula as a complication of Nissen fundoplication has, to the best of our knowledge, not been reported previously. We report on a case of esophagobronchial fistula in a patient with left subphrenic abscess following redo Nissen fundoplication. Chest radiographs suggested an unresponsive pneumonia of the left lower lobe. Computed tomography (CT) of the abdomen showed partial consolidation of the left lower lobe and contrast filling of the left bronchial tree from a left subphrenic abscess. CT diagnosis of fistula originating from the region of fundoplication was confirmed by Gastrografin® follow-through.

    Notes: Abstract The value of magnetic resonance imaging (MRI) and magnetic resonance cholangiopancreatography (MRCP) is demonstrated in a case of a 22-year-old female with a small choledochocele clinically presenting with acute cholecystitis and pancreatitis. Previous abdominal sonography and computed tomography were not diagnostic. MRI and MRCP showed a cystic dilatation of the distal common bile duct, intramurally located in the second portion of the duodenum and protruding into the duodenal lumen. These findings allowed a confident diagnosis of a choledochocele.

    Imaging findings in diffuse axonal injury after closed head trauma (1998)
    Springer

    Notes: Abstract. Even in patients with closed head trauma, brain parenchyma can be severely injured due to disruption of axonal fibers by shearing forces during acceleration, deceleration, and rotation of the head. In this article we review the spectrum of imaging findings in patients with diffuse axonal injuries (DAI) after closed head trauma. Knowledge of the location and imaging characteristics of DAI is important to radiologists for detection and diagnosis. Common locations of DAI include: cerebral hemispheric gray-white matter interface and subcortical white matter, body and splenium of corpus callosum, basal ganglia, dorsolateral aspect of brainstem, and cerebellum. In the acute phase, CT may show punctate hemorrhages. The true extent of brain involvement is better appreciated with MR imaging, because both hemorrhagic and non-hemorrhagic lesions (gliotic scars) can be detected. The MR appearance of DAI lesions depends on several factors, including age of injury, presence of hemorrhage or blood-breakdown products (e. g., hemosiderin), and type of sequence used. Technical aspects in MR imaging of these patients are discussed. Non-hemorrhagic lesions can be detected with fluid attenuated inversion recovery (FLAIR), proton-density-, or T2-weighted images, whereas gradient echo sequences with long TE increase the visibility of old hemorrhagic lesions.

    New concepts in understanding evolution of desmoid tumors: MR imaging of 30 lesions (1997)
    Springer
    European radiology 7 (1997), S. 1013-1019

    ISSN: 1432-1084
    Keywords: Key words: Desmoid ; Aggressive fibromatosis ; Soft tissue tumor ; MR imaging

    Topics: Medicine
    Notes: Abstract. The objective of this study was to evaluate the appearance and the natural evolution of desmoid tumors on MR imaging, given histologic correlation. The MR images of 30 desmoids (20 primary and 10 recurrent) in 26 patients were scored for a multiplicity of morphological parameters, signal intensity (SI) on different pulse sequences, and behavior after contrast administration. Natural evolution was evaluated in 2 primary and 3 recurrent lesions, and correlated with evolution on histologic specimens. Desmoid tumors are mostly found in muscles of shoulder and hip girdle and are often fusiform with partially ill-defined margins. Rare subcutaneous desmoids have a more stellar morphology. Variable amounts of low-SI areas are present on all sequences. On T1-weighted images (T1-WI), most lesions are near homogeneous and isointense to muscle, whereas on T2-WI they are more heterogeneous with an overall SI equal to or slightly lower than fat. Histologic correlation reveals that SI on T2-WI cannot be explained solely by cellularity. After initial growth, spontaneous evolution of desmoids is characterized by shrinking and an increase in low-SI areas on T2-WI. While distal lesions shrink, the more recent lesions in asynchronous multicentric desmoids have a tendency to develop proximally in the same limb, and should not be confused with recurrences. Fast growth, extracompartmental spread, and bone involvement are often seen in recurrences. Follow-up MR imaging of desmoids indicates natural regression of desmoids and more aggressive behavior of recurrences, which may justify a more conservative therapeutic approach.

    Notes: Abstract. We report a rare case of dysplasia epiphysealis hemimelica (DEH) in the wrist of a 7-year-old boy. Clinical, radiological and histopathological manifestations are discussed. The correct diagnosis of DEH, however, was made by the confrontation of the radiological and pathological data. The radiologist should inform the pathologist correctly about the imaging findings in order to avoid misdiagnosis of the lesion as osteochondroma.

    Subcutaneous granuloma annulare: MR imaging and literature review (1998)

    Notes: Abstract. Subcutaneous granuloma annulare (SGA) is little known to radiologists. Better knowledge of this lesion may prompt accurate diagnosis. A typical case is presented with plain radiography, ultrasound and MR imaging, and is confirmed by histology. When an otherwise healthy child presents with a rapidly growing, solitary, nontender, subcutaneous soft tissue mass, located on the scalp or extensor aspect of the limbs, that radiologically presents as an indistinct radiodense and hypoechoic mass, isointense to muscle on T1- and slightly hypointense to fat on T2-weighted MR images, without calcifications, bone involvement or extracompartmental invasion, SGA should be suspected.

    Intestinal stenosis from mesenteric injury after blunt abdominal trauma (1999)

    Notes: Abstract. We report a case in which blunt abdominal trauma resulted in injury to the mesentery with subsequent ischemic stricture of the adjacent small bowel. We present CT images at the time of trauma and 5 weeks later when clinical signs of intestinal obstruction occurred. We include images of enteroclysis and angiography of this uncommon sequela of blunt abdominal trauma. At surgery, a stenotic small bowel loop was found adjacent to a healed defect in the mesentery. Histological examination of the resected segment showed mucosal and submucosal ischemia with mucosal ulceration, mural inflammation, and fibrosis. Posttraumatic intestinal stenosis subsequent to a mesenteric tear should be included in the differential diagnosis in a patient with a history of blunt abdominal trauma and signs of intestinal obstruction.

    Diagnosis and nonsurgical management of bile leak complicated by biloma after blunt liver injury: report of two cases (1998)

    Notes: Abstract. We report on two patients with biliary tract injury and associated biloma following blunt abdominal trauma. Both patients underwent emergency surgery because of hemodynamic instability and bloody peritoneal aspiration. Computed tomography in the postoperative days showed severe hepatic parenchymal injury and the presence of hypodense collections with intraparenchymal and subcapsular extension, suggestive for biloma, but otherwise failed to demonstrate the exact location of the bile duct injury. One of them underwent temporary percutaneous drainage. Bile duct injury was well demonstrated on endoscopic retrograde cholangiography (ERCP) and treated by endobiliary stent placement. This report advocates the use of ERCP and endobiliary stenting in the management of biliary injury resulting from liver trauma.

    Notes: Abstract. Transient myometrial contraction as a physiological phenomenon may simulate pathological conditions, such as a focal or diffuse adenomyosis. Clinicians should be aware of the potential presence of this phenomenon and imaging should be repeated after a suitable interval when the nature of a bulge or a region of low intensity in the myometrium is in doubt. In this paper, we report a transient myometrial contraction that mimics an adenomyosis, but disappears in repeated series.
