[Ultrasonic diagnosis of "hematoma" of the sternocleidomastoid muscle].

Fifty-five patients (38 and 17), whose age ranged 14 to 153 days, with a clinical suspicion of sternocleidomastoid mass, were examined with US. Neck movements were impaired in all patients and 6 of them exhibited no clinically palpable mass. Sternocleidomastoid masses were detected in 50 patients. Other neck masses (lymphadenopathy, neuroblastoma, lymphangioma) were demonstrated in the remaining 5 patients. US sensitivity was confirmed to be higher than that of clinical palpation in detecting the masses. Our results show that males (69%) and the right side (80%) were mostly affected. The sternal head (92%) and the lower third of the muscle (88%) were most commonly involved. Forty-four masses (88%) had homogeneous echostructure and their echogenicity relative to normal muscle was mostly isoechoic in 33 patients (66%) and hyperechoic in 11 patients (22%). Six masses (12%) had a patchy echotexture and mixed echogenicity. No cases of mostly hypoechoic echotexture or intralesional calcifications were observed. The mass to muscle ratio in the largest transverse sections ranged 25-175% (mean: 95%). Sternocleidomastoid masses disappeared in all 50 patients within their 6th month of age. US is confirmed as a valuable tool to diagnose and follow-up sternocleidomastoid masses.

[Echographic diagnosis of thyroid hemiagenesis].

Thyroid hemiagenesis is a rare anomaly with an uncertain incidence, since some patients have been found in a euthyroid state without abnormalities. Females account for 75% and males account for 25% of the cases, giving a female to male ratio of 3:1. The left lobe is absent in 80% of cases and the right lobe is absent in 20% of cases (a left to right hemiagenesis ratio of 4:1). The isthmus is absent in 50% of the patients. A variety of pathological conditions have been found in the remaining thyroid tissue in association with thyroid hemiagenesis: hyperthyroidism, multinodular goiter, hypothyroidism, benign adenoma, adenocarcinoma, Grave's disease. The differential diagnosis would include unilateral inflammatory disease and infiltrative disease, such as amyloidosis. We present two cases diagnosed in pediatric age, with absence of the left lobe and of the isthmus. Thyroid hemiagenesis has been found in association with congenital hypothyroidism in one case. The other patient was found to be in a euthyroid state without abnormalities. The diagnosis of thyroid hemiagenesis should be considered in any patients where, on physical examination, no apparent thyroid tissue is noted on one side of the neck. Sonography demonstrates an absent lobe, an eventually absent isthmus, and an eventually coexiting pathological condition in the remaining thyroid tissue. Sonography may be useful in distinguish between unilateral thyroiditis or other infiltrative processes and true hemiagenesis. Scintigraphy shows the remaining thyroid tissue uptake, and may reveal ectopic thyroid tissue not seen by ultrasound. Ultrasound may be useful in monitoring asymptomatic patients according to the high frequency of pathological condition associated with thyroid hemiagenesis.

[Ultrasonographic findings in Osgood-Schlatter disease].

The Osgood-Schlatter disease affects the patellar tendon in its attachment to the tibial tuberosity. It is quite frequent in adolescents, especially in young males practising sports. Its diagnosis is mainly clinical. The findings of tenderness and focal swelling of the tibial tuberosity are typical of this condition. The Osgood-Schlatter disease can damage bone, cartilage, tendon and serous bursa. US yields complete information on the involvement of these structures. High-resolution US of the knee was performed on 70 patients with clinically suspected Osgood-Schlatter disease. More or less apparent cartilage swelling was demonstrated in 100% of our patients, tibial tuberosity fragmentation in 75%, diffuse thickening of the patellar tendon, at times inhomogeneous, in 22% and finally bursitis of the infrapatellar bursa was demonstrated in 17% of our patients. US provides complete information on the involvement of the tibial tuberosity and of the surrounding soft tissues, thus proving to be a simple and reliable method to diagnose the Osgood-Schlatter disease. Moreover, US is suitable for the periodical follow-up of disease course.

[Persistent multiple urachal complex. Echographic-surgical correlations].

Urachus is a tubular structure lined between foetal bladder and the umbilicus and is susceptible to complete or partial involution after birth. Persistence of the urachus results in a wide spectrum of anomalies: patent urachus, vesicourachal diverticulum, urachal sinus and cysts are more frequently seen than rare multiple urachal remnants. This kind of pathology focuses the problem of differential diagnosis (tumours, omental and ovarian cysts, vesical diverticulum or duplication) and may be complicated by a superinfection. The Authors discuss a bizarre multiple urachal remnant, presenting with urinary tract symptoms, which may be clinically confused with acute appendicitis or Meckel's diverticulitis. Contribution of sonography for a complete diagnosis is stressed, such as the precise correlation with surgical findings.

[The echographic diagnosis of Candida albicans cystitis in childhood].

Candida albicans infections are opportunistic and range from asymptomatic infections to life-threatening involvement, with a wide spectrum of clinical manifestations. Urinary tract involvement is usually secondary to systemic infection, although the kidney or the bladder may be primarily infected without other organs being involved. Renal fungus infections, most commonly due to Candida, are usually seen in patients with altered host resistance due to diabetes, malignancy, other chronic illnesses, or prolonged antibiotic, corticosteroid or immunosuppressive therapy. Herein we report on an immunosuppressed 12 years-old girl with Candida albicans cystitis diagnosed with US. Sonography demonstrated a discrete dense fluid-fluid interface within the bladder, mobile with changes in position. US was used to monitor the progress of therapy. Treatment is usually conservative, related to removing the precipitating factors (catheters, antibiotics, steroids). Indeed, in our case, the immunosuppressed patient needed aggressive therapy: i.v. fluconazole. Sonography 15 days after treatment showed a normal bladder, without significant sequelae or the formation of vesical concretions.

Postaxial acrofacial dysostosis or Miller syndrome. A case report.

A case of postaxial acrofacial dysostosis (Miller syndrome) is presented. This rare syndrome is essentially characterized by a Treacher-Collins-like facial appearance together with absence of the fifth digital ray of all limbs and variable forearm hypoplasia.

[Giant parietal foramina. A surgical defect?].

Sinus pericranii is unusually demonstrated in the region of the obelion. The radiological findings are those of large parietal foramina and the overlying soft tissue is bulging, suggesting vascular collection. The possible relationship between ossification of parietal bone and vascular anomaly is discussed.

Lumbo-sacral radiculography with a new, water-soluble contrast medium: myelografin (meglumine ioserinate, SSH 239 AB).

The authors present the results of a clinical trial of a new water-soluble contrast medium for radiculography: meglumine ioserinate. This trial was conducted on eighty eight patients in the Orthopaedic Clinic of the University of Rome between 1975 and 1976. The patients were subdivided into two groups, one of fifty four in whom a single dose of 5 ml was injected, the other of thirty four who received a double dose of 10 ml of contrast medium. In the latter the medium was always injected undiluted. No disturbances following radiculography were reported by 58 per cent of the first group and 44 per cent of the second. The clinical side-effects encountered in the other patients are analysed. These side-effects were negligible in the majority of cases, and occurred less frequently than with meglumine iothalamate, and at least more often than with meglumine iocarmate. Finally, the findings in the cerebrospinal fluid are described, before and twenty four hours after the test, in a small group of these patients. The contrast and diffusibility were found to be excellent, as also was the tolerance, which has the advantage that the patient can be kept in the horizontal position after the examination. Despite this, because of some changes encountered in the cerebrospinal fluid, and because of a convulsive episode presented by one patient treated with the double dose, the authors advise diluting the contrast medium in distilled water, so as to lower the osmotic pressure.
