[Cerebral hydatid disease: imaging features].

Cerebral hytatid cysts (HC) are extremely rare, forming 2% of all intra cranial space occupying lesions even in counties where the disease is endemic. HC diagnosis is usually based on a pathognomonic computed tomography (CT) pattern. In order to assess the value of MR we reviewed the CT (n=25) and magnetic resonance (MR, n=4 including diffusion and proton magnetic resonance spectroscopy in 1) imaging of 25 patients with pathologically confirmed cerebral hydatid disease. 19 HC were seen in children under 16 years. All were supra tentorial with 22 in the middle cerebral artery territory. HC was solitary in 18 cases, unilocular in 23 and multi-vesicular in 2 with heavily calcified pericyst in 1. 2 cysts were intra ventricular and 1 intra aqueducal. The most typical features were well defined, smooth thin walled spherical or oval cystic lesions of CSF density and/or signal with considerable mass effect (20/25). Surrounding oedema with complete or incomplete rim enhancement was seen in 3 cases which were labelled as complicated and/or infected cysts. Although CT is diagnostic of hydatid disease in almost all cases (22/25), MRI including diffusion and spectroscopy precisely demonstrate location, number, cyst capsule, type of signal and enhancement and allows diagnosis of atypical or complicated HC and appears more helpful in surgical planning.

[Esophageal mucocele: report of 2 pediatric cases].

Two cases of esophageal mucocele in pediatric patients are reported: two children of 5 and 9 years respectively underwent surgical isolation of the esophagus and esophagocoloplasty for caustic stenosis related to accidental ingestion of caustic soda. Clinical pattern of mediastinal compression was proved with cervical fistulous tract in one case. In both cases, thoracic computed tomography was a sensitive imaging method to demonstrate the mucocele and its extension. Esophageal mucocele is rarely described in children, especially following esophageal corrosive stricture.

[Post-traumatic adenoid cystic carcinoma of the lacrimal gland].

A young 17-year-old man was injured on the external orbital canthus and developed a tumefaction which remained stable. After 2 years the tumefaction with exophthalmia and visual troubles. Radiological investigations suggested two diagnosis: Organized hematoma or a lacrimal gland tumor. Surgical exploration found an apparently benign tumor but histologically it was a cystic adenoid carcinoma.

[Acute pyelonephritis and subcapsular hematoma revealing nephroblastoma at the age of 15 years].

BACKGROUND: Nephroblastoma' the most common renal tumor in children between 1 and 5 years, occurs rarely in the oldest child. CASE REPORT: A 16-year-old teenager suffered from acute pyelonephritis caused by Klebsiella pneumoniae. Renal ultrasonography showed a left subcapsular hematoma; the CT scan confirmed the finding and also showed renal scarring. However, a second CT scan showed pulmonary nodules suggestive of metastasis, a diagnosis that was confirmed by needle biopsy of pulmonary lesions. Recovery was obtained after chemotherapy and nephrectomy with a 3-year-follow-up. CONCLUSION: This nephroblastoma was particular because its development in an adolescent, its association with acute pyelonephritis and subcapsular hemorrhage.

[Ultrasonographic aspects of kidney pelvis tumors associated with infectious hydronephrosis of lithiasic origin].

The ultrasonographic findings of 4 patients with surgically confirmed urothelial tumors associated with calculic pyonephrosis are presented. All the involved were markedly enlarged and hydronephrotic with obstructive calculi, stigmata of pyonephrosis and, an echoic pelvic mass, extending in calyceas in 2 cases. The sonographic appearance correlated well with the gross pathological findings. The histological types were 2 squamous cell carcinomas, 1 adeno-squamous cell carcinoma and 1 transitional carcinoma. The chronic calculic irritation was proved to induce squamous and glandular metaplasia. The subsequent squamous carcinoma and adenocarcinoma were documented in the literature. The preoperative diagnosis of the associated tumor was rarely done. The sonographic features reported are highly suggestive of urothelial tumor and may lead to an accurate preoperative diagnosis.

[Non-surgical treatment of kidney abscesses. Apropos of 12 cases].

Twelve renal abscesses were treated with percutaneous aspiration (6 patients), percutaneous drainage (3 patients) or antibiotics alone (3 patients). The diagnosis was established based on computed tomography-guided aspiration in 9 cases and on radiographic findings and follow-up in the remaining 3. A bacterium was isolated in 2 out of 9 blood cultures, 2 out of 11 urine cultures and in all cultures of pus obtained by percutaneous aspiration. All patients had a good outcome. Our findings confirm the efficacy of percutaneous aspiration in the treatment of renal abscesses. Percutaneous drainage should only be considered when the abscess is very large or aspiration has failed.

[Adrenal tumors in Beckwith-Wiedemann syndrome. Apropos of a case].

A case of a neonate with Beckwith-Wiedemann syndrome is presented. Antenatal sonography detected a right adrenal cystic mass confirmed in post-natal which resolved spontaneously within 1 month. The child developed an adrenal adenoma detected by abdominal sonography at six months of surveillance. The authors review the different adrenal lesions possibly associated with Beckwith-Wiedemann syndrome and specially the pseudo-tumorous lesions. The value of abdominal sonography in the neonatal periods and in the surveillance of children with Beckwith-Wiedemann syndrome is emphasized.
