Bronchial perforation and bronchoesophageal fistulas: tuberculous origin in children.

A case of bronchial perforation and two cases of bronchoesophageal fistula of tuberculous oritin are presented. The lesions were radiologically identified by bronchography in one patient and esophagography in the other two. One patient with bronchoesophageal fistula died. His lesion had been erroneously considered to be congenital. At surgery, widespread pulmonary tuberculosis was found. The other two patients responded to antituberculous chemotherapy. In one of them, a follow-up barium esophagogram showed a large esophageal diverticulum located where a previous fistulous opening had closed.

Traumatic pharyngeal pseudodiverticulum in neonates and infants. Two case reports and review of the literature.

Thirty one cases of pharyngeal pseudodiverticulum have been reported in the literature; twenty nine were diagnosed during the neonatal period. Respiratory distress, increased oral secretions, difficulty with feeding and the impossibility of passing a nasogastric catheter were the most common symptoms and/or signs. Pneumomediastinum, pneumothorax, cervical emphysema and ectopic location of a feeding catheter, alone or in combination, were identified in the chest roentgenograms of 16 patients. Esophagography and/or endoscopy were the diagnostic methods of choice. The exact location of the perforation was identified in 18 patients. Most of the perforations were in either the posterior pharyngeal wall or in the pyriform sinuses. The survival rate was as good amongst the medically treated patients as in those who underwent surgery.

Mastocytosis with skeletal and gastrointestinal involvement in infancy. Two case reports and a review of the literature.

Two cases of mastocytosis with skeletal involvement in children three and six months old are reported. Bone lesions, either sclerotic or lytic, were encountered in their skeletal surveys. Gastrointestinal lesions in children with mastocytosis are exceedingly rare; in addition to skeletal lesions, one of our patients had a large duodenal ulcer. The diagnosis of mastocytosis was established by skin biopsy in both patients. A review of the literature is also presented.

Congenital dilatation of the intrahepatic bile ducts (Caroli's disease).

Caroli's disease (congenital dilatation of the intrahepatic bile ducts) was diagnosed in an 11-year-old girl with the aid of intravenous cholangiography. Recurrent abdominal pain, fever, and intermittent obstructive jaundice are the most common symptoms and usually develop during childhood or young adulthood. Operative cholangiography has been the most valuable method of diagnosing the condition and determining the location and extent of the disease process.

[Acceleration of postnatal development, hypertony, enlargement of the middle phalanges and of the distal metaphyses of the femur, peculiar facies: a case of Weaver's syndrome?].

A child is described with accelerated bone maturation, large dysplastic ears, and hypertelorism. These are features of both the Marshall-Smith and Weaver's syndrome. The child was mentally retarded and had enlargement of the middle phalanges, features only seen in Marshall-Smith syndrome. However, there was also enlargement of the metaphyses, a characteristic of Weaver's syndrome. The possiblity that these syndromes may represent different manifestations of the same entity is discussed.

[Radiological features of urinary tract infection in childhood (author's transl)].

The diagnosis of one documented urinary tract infection in children establishes indication for carrying out a radiologic investigation of patient's urinary tract. Such an approach is mostly aimed at recognizing the presence of predisposing factors such as congenital malformations. Upon mentioning available techniques and its indications, the author describes radiologic findings of the most common inflamatory diseases of the urinary tract in childhood.

Spectrum of manifestations of Swyer-James-MacLeod syndrome.

PURPOSE: The clinical and imaging findings of children with Swyer-James-MacLeod syndrome (SJMS) were reviewed to determine the incidence and type of bronchiectasis and analyze whether the clinical course of patients with bronchiectasis differed from that of patients without bronchiectasis. METHOD: Our study population consisted of 13 patients. All had inspiratory/ expiratory chest X-ray films, chest CT, and lung scans. Eight underwent pulmonary function test. The results of these studies at diagnosis and during follow-up were analyzed and compared with the clinical features. RESULTS: Bronchiectasis was demonstrated in nine patients, being saccular in five and cylindrical in four. Expiratory slices were helpful for demonstrating bilateral lung involvement that had not been suspected on inspiratory CT scans or conventional radiographs. The clinical features of the five patients with saccular bronchiectasis resembled those of patients with classic postviral bronchiectasis who suffered recurrent pulmonary infections; three of them underwent lobectomy. The remaining patients presented mild respiratory symptoms, with a spontaneous tendency toward improvement. CONCLUSION: SJMS should be considered as a spectrum disease. Bronchiectasis is not a universal finding. The presence and type of bronchiectasis will influence clinical manifestations and prognosis. Patients without bronchiectasis or with cylindrical bronchiectasis had a lower incidence of pneumonia episodes than those with saccular bronchiectasis.

Cervicothoracic lesions in infants and children.

Cervicothoracic lesions are not uncommon in children. All cervicothoracic lesions except superficial lesions extend from the neck to the thorax through the thoracic inlet. Evaluation of this area involves multiple imaging modalities: plain radiography, ultrasonography, nuclear medicine, computed tomography, and magnetic resonance (MR) imaging. However, MR imaging is the method of choice for assessing the full extents of cervicothoracic lesions and their relationships to neurovascular structures. Cervicothoracic lesions can be classified as congenital lesions, inflammatory lesions, benign tumors, malignant tumors, and traumatic lesions. Lymphangioma is the most common cervicothoracic mass in children; other congenital lesions include hemangioma, thymic cyst, and vascular anomalies. Inflammatory adenopathy reactive to tuberculosis, mononucleosis, tularemia, cat-scratch fever, infection with human immunodeficiency virus, or other upper respiratory tract infections can manifest as cervicothoracic lesions; tuberculous abscesses and abscesses of other origins can also be seen. Lipoma, lipoblastoma, aggressive fibromatosis, and nerve sheath tumors (either isolated lesions or those associated with neurofibromatosis) can also occur as cervicothoracic masses. Malignant cervicothoracic tumors include lymphoma, thyroid carcinoma, neuroblastoma, and chest wall tumors (rhabdomyosarcoma, Ewing sarcoma, and neuroectodermal tumor). Traumatic cervicothoracic lesions include pneumomediastinum of traumatic origin, traumatic pharyngeal pseudodiverticulum, esophageal foreign-body granuloma, and cervicothoracic hematoma.

Worklists, preloading and archiving strategies; 3 years of clinical experience in the Barcelona PACS.

We present data on 3 years of clinical experience using PACS involving developments on worklists, preloading and archiving strategies in a teaching paediatric hospital with all modalities connected to a commercial PACS. A method allowing generation of and handling of different worklists for computed radiography examinations has been developed in our centre. Worklists and archiving strategies are presented and discussed. We conclude that, with adequate worklists and efficient preloading implementation, current PACS could be used successfully in several clinical settings of a multimodality department.
