Imaging of neonatal pulmonary sequestration including Doppler ultrasound.

Seven cases of neonatal pulmonary sequestration are reviewed which illustrate the varied clinical presentations and radiological findings. In four patients, real time ultrasound scanning was used to image the chest and the features are described. In three cases, the systemic supplying artery was demonstrated by duplex Doppler scanning and further invasive investigations were avoided; after a chest radiograph, this should be the examination of choice in the investigation of a neonate with a possible pulmonary sequestration.

Initial investigation of childhood urinary tract infection: does the plain abdominal X ray still have a role?

To reassess the plain abdominal X ray (AXR) in the initial investigation of childhood urinary tract infection, radiologists from four paediatric units prospectively collected data on the yield from the AXR in 683 children. Five children had renal calculi. All were detected on ultrasound, but one was not visible on the initial AXR. Four spinal abnormalities were identified, none of which prompted any action by the clinician involved. While the costs, in both financial and radiation risk terms, may be small, the benefit of the AXR appears equally small. Where expert paediatric ultrasonography is available we would recommend that the AXR be reserved for patients with haematuria, loin pain, family history of calculus disease, or where further urinary tract infection occurs despite a normal ultrasound scan.

Complete laryngotracheoesophageal cleft: CT diagnosis and associated abnormalities.

A case of complete laryngotracheoesophageal cleft is described in a male infant in which bronchoscopy could not be performed due to a narrow tracheal orifice. CT scan of the thorax demonstrated a common tracheal and oesophageal lumen extending inferiorly to the carina, with hypoplasia of the right lung and cardiac dextroposition. Contrast studies demonstrated a hypoplastic intrathoracic stomach. Chromosome analysis revealed satellites on the Y chromosome with karyotype 46XYqs.

Fibromuscular dysplasia of the renal artery in a child: detection by Doppler ultrasound and correction by percutaneous transluminal angioplasty.

We describe the case of a fourteen-year old girl with hypertension, in whom renal arterial stenosis was identified by Doppler ultrasound examination, with subsequent demonstration of typical features of fibromuscular dysplasia by selective renal arteriography. Percutaneous transluminal balloon angioplasty was performed, and a sustained improvement in renal arterial flow was confirmed by follow-up Doppler ultrasound examinations.

Arthrosonography of the irritable hip in childhood: a review of 1 year's experience.

A retrospective study of 87 children presenting acutely with an "irritable hip" was undertaken to assess the role of arthrosonography of the hip joint. Arthrosonography detected 52 hip-joint effusions, of which 16 were aspirated and an effusion confirmed in 14 (88%). In 82 cases plain radiography was compared with arthrosonography for the detection of hip-joint effusions. Of 47 children with a positive ultrasound diagnosis, 28 (59%) showed abnormal findings on plain radiographs and, of 35 cases with negative ultrasound findings, 22 (63%) had a negative diagnosis by plain radiography. Patients with more severe clinical signs were more likely to have an ultrasonic diagnosis of an effusion (87%-100%) than those with mild clinical signs (25%). The ultrasonic measurement of the hip-joint capsule to femoral neck distance was 2.2 mm +/- 0.5 mm (mean +/- 1 SD) in normal hips and 6.3 mm +/- 1.5 mm in the joints with effusions. Our study suggests that arthrosonographically the normal capsular space is less than 3 mm and the difference between the two sides less than 2 mm. It is suggested that hip arthrosonography is a more accurate method for detecting hip-joint effusions than plain radiography; it may help select cases for hospital admission and should be performed before aspiration is attempted.

Real time ultrasound scanning of the head in neonates and infants, including a correlation between ultrasound and computed tomography.

The results of ultrasound (US) head scans performed in a children's hospital over a 6 month period have been reviewed and correlated with the results of computed tomography (CT). Two hundred and twenty-four scans were performed on 141 children ranging in age from a few days to 18 months. The clinical indications with which these children were referred were: abnormal neurological symptoms or signs, screening for hydrocephalus in neural tube defects (NTD), enlarging heads, suspected intra-cranial haemorrhage (ICH) and its sequelae, suspected complications of meningitis, investigations of suspected syndromes and following trauma. Twenty-nine of these children also had CT scans. There was good correlation between the two examinations and in only one case (a subdural collection) was a serious abnormality missed by US. US head scanning has been found to be a very reliable technique. It is the initial investigation of choice for imaging the brain of neonates and infants and in many instances it is the only investigation necessary.

Rickets of prematurity: calcium and phosphorus supplementation.

Seventy-four infants weighing less than 1500 gm at birth were fed enterally from birth until day 47. Group A (18 infants) were given SMA Gold Cap: group B (18 infants), supplementary calcium to 21 mmol/L (84 mg/dl); group C (16 infants), further calcium supplementation to 31.2 mmol/L (125 mg/dl); and group D (22 infants), milk with calcium content 31.2 mmol/L (125 mg/dl) and phosphorus supplementation to 15.7 mmol/L (49 mg/dl). The addition of calcium reduced the radiologic evidence of rickets, and combined calcium and phosphorus supplementation maintained plasma alkaline phosphatase activity within the normal range for 6 weeks.

The ultrasonic appearances of the septa of Bertin in children.

The ultrasonic appearances of the septa of Bertin are described in relation to eight children. These septa may be of varying echogenicity from the remaining cortex and may lead to a misdiagnosis of a true pathological lesion. In our series, two children had an initial suspicion of an abdominal mass; one an intrarenal neoplasm and the other an intrarenal haematoma. It is of importance to recognise this normal variation to avoid misdiagnosis of a pathological mass and to avoid further unnecessary investigation.

Abdominal ultrasound in the diagnosis of cerebrospinal fluid pseudocysts complicating ventriculoperitoneal shunts.

Pseudocysts filled with cerebrospinal fluid caused complications at the distal end of ventriculoperitoneal shunts in five children. Only one of these cysts was infected. The children presented with raised intracranial pressure or abdominal symptoms, or both. We report on the usefulness of abdominal ultrasound examination in the diagnosis and follow up of these patients and suggest that abdominal ultrasound should form part of the initial assessment of children with ventriculoperitoneal shunt dysfunction.
