The "nutcracker phenomenon" with orthostatic proteinuria: case reports.

The nutcracker phenomenon refers to compression of the left renal vein between the aorta and the superior mesenteric artery. Clinical features are hematuria, abdominal pain, left flank pain, pelvic or scrotal discomfort due to varicocele or ovarian vein syndrome. In this report, 2 patients with orthostatic proteinuria, in whom nutcracker phenomenon was detected as a cause, are presented. One of them had posterior nutcracker with also asymptomatic varicocele that was detected during ultrasonographic examination. Nutcracker phenomenon is a rare but important clinical condition that should be considered in the differential diagnosis of patients with proteinuria and hematuria.

Low back pain as the initial symptom of inferior vena cava agenesis.

Inferior vena cava (IVC) agenesis is a rare anomaly that is usually an incidental finding in radiologic work-up or it can rarely be symptomatic due to deep venous thrombosis of iliac veins. In this report, we present a case of IVC agenesis detected on lumbar spinal MR imaging scans by extensive epidural-paravertebral collateral vessels compressing the thecal sac and causing low back pain in a child.

Hypertrophic osteoarthropathy in a child with biliary atresia.

Hypertrophic osteoarthropathy is a syndrome characterized by clubbing of the digits of the hand/foot, periosteal reaction and arthralgia or arthritis which is usually secondary to cyanotic congenital heart disease and chronic pulmonary infections. This syndrome rarely occurs in association with chronic liver disease in childhood. Here, we report on a child with biliary atresia who developed arthralgia and arthritis during follow-up and which was diagnosed as hepatic hypertrophic osteoarthropathy. It is emphasized that hypertrophic osteoarthropathy should be considered in the differential diagnosis of arthralgia and arthritis in children with long-standing chronic liver diseases, especially if finger clubbing is also present.

Frequency of mtDNA A1555G and A7445G mutations among children with prelingual deafness in Turkey.

UNLABELLED: Considerable differences on the frequencies of the mitochondrial 12S rRNA A1555G and tRNA(Ser(UCN)) A7445G mutations have been reported in different populations. Our screening of 168 patients coming from independent Turkish families with prelingual sensorineural non-syndromic deafness revealed three deaf children with A1555G (1.8%) but no examples of A7445G. One proband with the mitochondrial A1555G mutation has also evidence for right parietal infarct on a brain imaging study, for which common thrombotic mutations were found to be negative. CONCLUSION: This study shows that the mitochondrial A1555G mutation is among the significant causes of prelingual non-syndromic deafness in the Turkish population.

A rare cause of cervical spinal stenosis: posterior arch hypoplasia in a bipartite atlas.

We describe CT and MRI of a previously unreported combination of atlantoaxial anomalies consisting of posterior arch hypoplasia in a bipartite atlas with an os odontoideum, in a 30-year-old woman presenting with neck and left arm pain. MRI showed the os odontoideum, marked stenosis of the spinal canal at the level of the atlas, with cord compression and evidence of myelopathy. CT revealed a bipartite atlas with midline clefts in anterior and posterior arches, thickening in the anterior arch and hypoplasia of the posterior arch with incurving of both hemiarches. Flexion and extension radiographs demonstrated atlantoaxial instability.

Intracranial lipoma with extracranial extension through foramen ovale in a patient with encephalocraniocutaneous lipomatosis syndrome.

We present CT and MR features of a large intracranial lipoma located in the left sphenocavernosal region in a patient with a history of spinal intradural lipoma excision. The lipomatous lesion surrounded the internal carotid artery and trigeminal nerve and extended extracranially into the infratemporal region through a smoothly dilated foramen ovale.

Post-traumatic intrasplenic pseudoaneurysms with delayed rupture: color Doppler sonographic and CT findings.

Post-traumatic intrasplenic pseudoaneurysms are very rare in children. Since pseudoaneurysms may expand a splenic hematoma and cause delayed splenic rupture, early diagnosis and treatment are crucial. In this report, we describe the case of a 12-year-old boy with a delayed splenic rupture caused by a splenic hematoma containing 2 pseudoaneurysms. Abdominal sonography showed free intraperitoneal fluid and a mildly enlarged spleen with a large heterogeneous area occupying the upper half of the organ. Two anechoic lesions (15 and 4 mm) were seen inside the hematoma near the splenic hilum. Color Doppler sonography demonstrated turbulent arterial flow within the lesions, suggesting pseudoaneurysms. On CT, the lesions enhanced simultaneously with the splenic artery in the arterial phase of contrast enhancement. CT also showed an intrasplenic arterial branch leading to the larger of the 2 pseudoaneurysms.

Gray-scale and color Doppler sonographic findings in intratesticular varicocele.

PURPOSE: We studied the gray-scale and color Doppler sonographic findings in intratesticular varicoceles in 7 testes in 5 patients. METHODS: The study group comprised 5 infertile men referred for scrotal sonography and found to have intratesticular varicocele. Patients were examined at rest and during Valsalva's maneuver in supine and standing positions. A diagnosis of intratesticular varicocele was made when intratesticular veins visible on gray-scale sonography showed retrograde flow on color Doppler sonography either spontaneously or during Valsalva's maneuver. The maximum diameter of dilated intratesticular veins and the predominant site of venous dilatation (mediastinum testis versus subcapsular) were recorded. RESULTS: Seven testes in 5 patients harbored visibly enlarged intratesticular veins that showed retrograde flow either spontaneously or during Valsalva's maneuver. The condition was bilateral in 2 patients and left-sided in 3 patients. The largest intratesticular vein measured less than 2.0 mm in diameter in 3 testes and was 2.0 mm or larger in 4 testes. In all affected testes, there was some degree of subcapsular venous dilatation, which in 3 testes was even more prominent than venous dilatation in the mediastinum testis. All intratesticular varicoceles were accompanied by extratesticular varicoceles. CONCLUSIONS: A threshold value of 2.0 mm seems inadequate for the diagnosis of intratesticular varicocele because obviously variceal venous structures with retrograde flow on color Doppler sonography may be smaller than 2.0 mm in diameter. Contrary to the previous descriptions of the entity, subcapsular veins may be affected to a greater degree than mediastinal veins in intratesticular varicocele.

Tuberculous fibrosing mediastinitis: CT and MRI findings.

Fibrosing mediastinitis is a rare entity usually caused by granulomatous disease. Most cases develop as a complication of histoplasmosis. Mediastinal involvement caused by tuberculosis most often produces focally enlarged lymph nodes, with diffuse mediastinal involvement a very unusual manifestation of disease. The authors describe a patient with extensive tuberculous fibrosing mediastinitis, in whom fibrotic masses produced compression of airways and vascular structures with resultant parenchymal changes.

DiGeorge syndrome associated with left lung aplasia.

We report a patient with clinical and cytogenetic findings consistent with DiGeorge-velocardiofacial syndrome and aplasia of the left lung. To the best of our knowledge, this is the first reported case of DiGeorge-velocardiofacial syndrome associated with unilateral lung aplasia. Gadolinium enhanced three-dimensional magnetic resonance angiography demonstrated associated right-sided aortic arch and left pulmonary artery agenesis.

Radiological findings in the diagnosis of genitourinary candidiasis.

The presence of fungus balls within the collecting system is an important clue to the radiological diagnosis of genitourinary candidiasis. In this report, an 8-month-old infant with this opportunistic infection is described. Emphasis is placed on the radiological findings of renal candidiasis, including previously unreported MR appearances. Sonographic and Doppler findings of accompanying Candida epididymitis are also described.

Radiologic findings in primary pulmonary leiomyosarcoma.

Leiomyosarcomas are uncommon smooth muscle tumors most commonly encountered in the female genital organs, gastrointestinal tract, and soft tissues. They are rarely encountered as primary pulmonary neoplasms. Herein we describe the conventional radiographic and computed tomographic findings in a patient with a pulmonary leiomyosarcoma.
