The tricho-rhino-phalangeal syndrome revisited.

The tricho-rhino-phalangeal syndrome (TRPS) is a rare congenital disorder, characterized by (1) a peculiar and somewhat pear-shaped nose, (2) sparse and brittle scalp hair, and (3) radiographic evidence of cone-shaped epiphyses of the hands. On the basis of clinical, radiographic and genetic criteria, two subtypes (type I and II) are discerned. We describe an intermediate "hybrid" variant of the TRPS in a patient with clinical and radiographic features of TRPS type I, but with a clearly abnormal karyotype, consistent with TRPS type II. The radiographic findings of the syndrome are reviewed, with particular emphasis on the cone-shaped epiphyses in the hands, the changes in the coxo-femoral joints and the atypical appearance of the pubic symphysis.

Paranasal sinus pathology in allergic and non-allergic respiratory tract diseases.

Two hundred and seventy patients with asthma and/or rhinitis (162 or 60% allergic, 108 or 40% non-allergic) were studied for sinus pathology by means of standard X-rays and tomograms. Sinus pathology was defined as abnormal sinus X-rays, either on standard or tomography. Fifty-four percent of the X-rays were classified as abnormal based on mucosal thickening, loss of translucency of the cavities of polyps. Asthma was significantly more often associated with sinus X-ray abnormalities (65.1%) than rhinitis and/or chronic cough (44.4%). Loss of translucency of the cavities is more frequent in children, whereas mucosa thickening becomes more frequent with progressing age. Since in this prospective study the taking of X-rays of the sinuses was not dependent on or related to temporarily occurring symptoms which could be attributed to acute sinusitis, the presence of sinus abnormalities on X-rays can be considered as an indicator of the chronicity of airways diseases and might provide an indication for prophylactic therapy of the associated airway disease in a continuous way. The importance of sinus tomograms is stressed, since only 32.5% of the patients with mucosa thickening could be detected on standard X-rays.

Roentgenographical detection of cocaine smuggling in the alimentary tract.

We report five cases of cocaine smuggling, by hiding multiple drug-filled foreign bodies in the colon, either after oral ingestion or by placing them in the colon per rectum. Several smuggling methods in the gastrointestinal (GI) tract and their radiological findings on abdominal plain film are presented. Computed tomography (CT) is found to be a more accurate method in the detection of the drug-filled bags, because of its improved contrast resolution and the absence of projections of overlapping structures on the transversal sections. Subsequently, CT is highly recommended in cases of negative or doubtful findings on conventional abdominal radiographs. In all cases conservative management was used and the drug-filled capsules and condoms passed spontaneously. No complications, such as intestinal obstruction by the bags of cocaine or intoxication by rupture of their wall were observed.

Intracranial tumors examined by intraarterial DSA: a comparative angiography study.

We compared intraarterial digital subtraction angiography (DSA) studies with those of conventional angiography, performed for 24 patients who had intracranial tumors. Intraarterial DSA is more effective in evaluating tumoral blush and venous phase, but neovascularization can be judged better by conventional angiography. In most cases, intraarterial DSA can replace conventional angiography for the diagnostic and preoperative evaluation of intracranial tumors. However, conventional angiography remains the technique of choice for the evaluation of neovascularization or if the patient is not cooperative.

Aphthoid esophageal ulcers in Crohn's disease of ileum and colon.

We report 4 cases of tiny aphthous ulcers of the esophagus occurring in patients with confirmed Crohn's disease of the terminal ileum and the colon. These ulcers presented as small collections of barium surrounded by a radiolucent halo, and were demonstrable on double-contrast radiographs of the esophagus. They were located in the middle and distal thirds of the otherwise normal esophagus. A more advanced stage of Crohn's ileocolitis was present in these patients.

Neurofibroma of the vagus nerve in the head and neck: a case report.

A case of a tumor of the vagus nerve, showing typical features of a neurofibroma, is presented. The natural history is reviewed, and several technical investigations, with particular reference to the contributions of magnetic resonance imaging and immunohistochemical techniques in the differential diagnosis, are discussed.

Choledochocele: diagnosis by magnetic resonance imaging.

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.

Esophagobronchial fistula following redo Nissen fundoplication.

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.

CT diagnosis and differential diagnosis of otodystrophic lesions of the temporal bone.

The purpose of this study was to assess the diagnostic and differential value of high-resolution computed tomography in the evaluation of temporal-bone dystrophies. The study group included 55 patients with osseous abnormalities of the temporal bone in general, and the labyrinthine capsule in particular. In 27 patients the CT scan revealed evidence of otodystrophic lesions. The CT findings in patients with otosclerosis (21 patients), osteogenesis imperfecta (two patients), fibrous dysplasia (one patient), Paget's disease (one patient) and osteopetrosis (two patients) are described. The CT scans of 17 patients revealed secondary osseous lesions due to metastasis (five patients), post-inflammatory changes (10 patients) or labyrinthitis ossificans (two patients). Normal variants and congenital mineralization defects were diagnosed in nine patients, Down's syndrome in two. Our results indicate the importance of high-resolution computed tomography as the primary imaging modality in evaluating osseous lesions of the temporal bone and labyrinth.

Reject analysis: a pilot programme for image quality management.

The radiographic film wastage and the different parameters affecting this wastage were analysed for a 9-week period at a 600-bed University Hospital. An overall reject rate of 7.6% was found. The different reasons for rejection were evaluated, while retake rate, relation between working experience of the personnel, amount of rejected films and total film wastage in surface (m2), were registered and analysed.
