We report tumoral calcinosis, an uncommon disease of uncertain origin, in an infant-only the sixth instance of the disease reported in this age group. The radiologic features are typical as illustrated by three modalities. The clinical, radiologic and pathologic features are discussed along with comments concerning possible etiologies and management.
McMahon M J - - 1996
BACKGROUND: Teratomas of the head and neck are rare and occur almost exclusively in neonates. Prenatal diagnosis of these tumors allows for a carefully planned delivery that maintains an open airway and potentially improves perinatal outcome. We report the perinatal management of a huge intrapharyngeal and intra-oral teratoma that had ...
Ferguson H L - - 1996
Cardiac fibromas are rare lesions which occur more frequently in infants and children than in the adult population. These tumors are nonmalignant proliferations of connective tissue most often found in the left ventricular myocardium or septal myocardium. No cytogenetic studies of cardiac fibromas have been reported. We report a case ...
Tsai S Y - - 1996
A 3-month-old Chinese male infant with typical manifestations of Beckwith-Wiedemann Syndrome (BWS), such as macroglossia, hepatomegaly, umbilical hernia and hypoglycemia, presented with a large hepatic tumor.

OBJECTIVES: The purpose of this study was to test observations that might aid prenatal prediction of the presence of coarctation of the aorta in newborn infants with and without other forms of heart disease. BACKGROUND: Previous reports have suggested that abnormal growth of the aortic arch in utero may be ...
Burns J R - - 1993
Branched renal calculi are extremely unusual in infants. We report a case of a partial staghorn calculus in a 9-month-old boy and discuss how techniques routinely used in the treatment of staghorn calculi in adults (extracorporeal shock wave lithotripsy, nephrostolithotomy, percutaneous irrigation) can be applied to the infant kidney.
Azumagawa K - - 1993
A 4-month-old male infant was seen because of an asymptomatic undescended left testis and a right sided abdominal mass. CT revealed a calcified retroperitoneal tumour. Histological examination of surgical specimens showed a mature primary teratoma of the contralateral undescended testis. While this is very rare, infants with undescended testis should ...
Resnick S D - - 1993
A 3-week-old infant had a massive hemangioma-like vascular neoplasm that had enlarged rapidly since being noted at birth. Less than a day after this initial evaluation the tumor underwent spontaneous ulceration and the infant had a near-fatal hemorrhage. Histologically, the tumor was a spindle cell neoplasm most consistent with the ...

Nmadu P T - - 1993
Gastric teratoma is a very rare, usually benign, tumour of childhood. In industrialized countries, the diagnosis is facilitated by advanced technology when the infant is still in utero or soon after birth, and surgery is performed quite early in life, long before symptoms appear. This tumour was seen in our ...
Hudson M E - - 1992
Teratomas of the testis in infants are rare tumors which often display immature elements, disturbing in their histologic appearance. Although the presence of similar histologic features worsens prognosis in testicular teratomas in adults and in teratomas of infants and children presenting at other anatomic sites, the presence of immature elements ...
Itoh M - - 1992
We report a 2-month-old female infant with a false aneurysm of the brachial artery and an 8-month-old male infant with a true aneurysm of a common digital artery. These traumatic aneurysms in the upper extremity are extremely rare in infants. In the former infant, reanastomosis of the brachial artery was ...
Brouwer M H - - 1992
Surgical treatment of a hypoplastic aortic arch associated with an aortic coarctation is controversial. The controversy concerns the claimed need to surgically enlarge the diameter of the hypoplastic arch, in addition to resection and end-to-end anastomosis. The purpose of this prospective study is to determine the fate of the hypoplastic ...

Proliferations of mature adipose tissue, while common in retroperitoneal and subcutaneous sites, rarely occur in the orbit. We describe the clinical, radiographic, and histopathologic findings of a nonencapsulated lipomatous tissue overgrowth of the right orbit in a 35-year-old man. The mass had caused proptosis since childhood and was apparently present ...
Dumbell H R HR Department of Paediatrics, University of Natal, - - 1990
A case of mediastinal teratoma, diagnosed in utero by realtime ultrasonography during a late 3rd trimester evaluation of polyhydramnios, is described. Prompt respiratory assistance to the infant at birth and early surgical intervention led to a successful outcome.
Sauter E R - - 1990
Oropharyngeal teratomas are rare congenital neoplasms that distort orofacial anatomy and often cause respiratory embarrassment at birth. Immediate management of such lesions should include establishment of a secure upper airway, radiographic exclusion of midline central nervous system anomalies, and early surgical excision to prevent asphyxia or permanent disfigurement. Perioperative assessment ...
Chien C H - - 1990
Immature mediastinal teratomas are rare, found in only 1% of all mediastinal teratomas; those occurring in the neonatal period are even more rare. A male baby suffering from tachypnea, weak crying and hoarseness since birth was noted, from a chest radiograph, to have a superior mediastinal mass. This mass enlarged ...
Whyte A M - - 1990
We report the case of a rapidly expanding mediastinal and chest wall lipoblastoma in an 11-month old infant. Clinical presentation was respiratory distress and chest radiographs revealed a large soft tissue mass in the anterior mediastinum without specific features. CT scanning demonstrated a mass of principally fat attenuation, with enhancing ...
