Adrenobronchial fistula complicating a neonatal adrenal abscess: treatment by percutaneous aspiration and antibiotics.

A case of retroperitoneal pulmonary fistula caused by a neonatal adrenal abscess is reported. The adrenal abscess was diagnosed by means of needle aspiration which guided the choice of antibiotic therapy. The fistula was demonstrated by direct injection of contrast medium into the adrenal abscess. Treatment by needle aspiration of the adrenal abscess and intravenous antibiotics was successful.

[A case of pulmonary mesenchymal hamartoma in a 9-year-old child].

This case of mesenchymatous hamartoma in a nine-year-old boy, was an incidental finding on a chest X ray. CT and MRI suggested the diagnosis showing a large (9 x 11 x 14 cm) mass developed in the right lower lung with sharp margins, without any sign of pulmonary or mediastinal compression. This lesion contained fatty areas on both CT and MRI. It showed no calcification. It enhanced slightly after IV contrast. On T2 WI, it appeared lobulated with low signal intensity septa. Presence of fatty tissues and lobulated margins were suggestive of the diagnosis of mesenchymatous hamartoma. A 1.2 kg mass was surgically removed. The tumor was attached to the right lower lobe by a small pedicle. Pathological examination disclosed fatty and connective tissues. This rare observation shows a good correlation between CT, MR, surgery and pathological examination.

[Value of percutaneous nephrostomy in the management of posterior urethral valves in newborn infants].

OBJECTIVES: This study evaluates the place of percutaneous nephrostomy (PCN) in neonates with posterior urethral valves (PUV). MATERIAL AND METHODS: 11 neonates with PUV, 10 of which were diagnosed antenatally, were treated. PCN drainage was performed in 9 cases, prior to endoscopic resection. Six PCN were bilateral and 3 were unilateral, for the following indications: renal failure in 5 cases, severe infection in 2 cases, evaluation of a dilated kidney in 2 cases. RESULTS: These PCN were left in place for an average of 18 days. Two cases of asymptomatic postoperative bacteriuria were observed. One nephrectomy and one cutaneous ureterostomy followed by reimplantation for megaureter were performed on the diverted kidneys. CONCLUSION: PCN has become the method of upper tract diversion in most cases of neonatal PUV. In addition to the classical indications (severe urinary tract infection, renal failure), it allows perfectly safe resection of valves in the case of upper tract dilatation and assessment of the kidneys.

[Gorham disease with prominent pleuropulmonary manifestation].

Gorham's disease usually manifests as diffuse osteolysis but may be complicated with pleural effusion. We describe the case of a 12 year-old boy who had repeated pleural effusions. Radiographs show a mediastinal widening and an interstitial syndrome related to hemolymphangiomatous involvement.
