Right nutcracker syndrome associated with left-sided inferior vena cava, hemiazygos continuation and persistant left superior vena cava: a rare combination

The term nutcracker syndrome refers to compression of left renal vein between aorta and superior mesenteric artery causing renal venous hypertension. Right nutcracker syndrome associated with a left-sided inferior vena cava is an extremely rare anomaly. Reported two cases in English literature were diagnosed by ultrasonography and computed tomography angiography in adulthood. Herein, we present a case of right nutcracker syndrome with left-sided inferior vena cava and hemiazygos continuation in a 12-year-old girl.

Suprasellar masses in children: Characteristic MR imaging features.

Pediatric suprasellar masses are unique in their clinical presentation and imaging features. The differential diagnosis, incidence, surgical approach and adjuvant treatment options differ from adult tumors. Magnetic resonance (MR) imaging is fundamental in preoperative evaluation and provides detailed information about the suprasellar region. In this article, we review the characteristic MR imaging findings of common suprasellar masses in children. We also briefly discuss useful MR imaging sequences and planes used in the initial evaluation of a pediatric suprasellar mass and clinical findings at presentation.

A Novel Approach to Lung Imaging in Children: Magnetic Resonance Imaging

Objective: There has been increased interest in magnetic resonance imaging (MRI) of the lung parenchyma in recent years. We aimed to evaluate the pulmonary MRI findings of patients in the light of literature data in this study. Material and Methods: Fifteen patients who underwent pulmonary MR imaging between April 2017 and January 2018 were included in our study. Demographic information, clinical preliminary diagnosis and imaging findings of the patients were retrospectively evaluated. Axial and coronal T2-weighted (T2W) and axial fat-saturated T2W images were obtained from all patients. Results: The mean age of the patients (7 girls, 8 boys) was 7.8 years (5 months -18 years). Lung MRI was used for the diagnosis of neutropenia-related infection during follow-up for hematologic-oncological diseases (n=6), lung hydatid cyst and follow-up of complications (n=2), metastasis scan (n=2), empyema diagnosis and/or follow-up of treatment (n=4), and lung mass-infection distinction (n=1). Twelve of the children were also imaged with computed tomography before lung MRI. In the follow-up MR imaging of patients with neutropenia and lung infection; the nodules and consolidated areas disappeared and became smaller in three patients, the number of nodules increased in one patient, and the number of nodules remained stable but became cavitated in one patient. In the patient with Fanconi aplastic anemia, a diagnosis of fungal infection was made by showing the reverse target sign on MRI. Patients with lung hydatid cyst and tuberculosis were differentiated from a lung mass easily. In the follow-up of three patients with necrotizing pneumonia 2 Yıldız AE ve Güneş A.

Lung Hydatid Cysts in Children: Imaging Findings of Complicated and Non-Complicated Lesions

Amac: Cocuklarda akciger kist hidatigi eriskinlerden daha sik gorulur. Akciger kist hidatigi bronsiyal ruptur ve/veya sekonder enfeksiyon ile komplike olabilir. Komplike lezyonlar ozgun olmayan goruntuleme bulgulari gosterebilir. Arastirmada komplike ve komplike olmayan akciger kist hidatiklerinin tanisal radyolojik bulgularinin karsilastirilmasi amaclanmistir. Gerec ve Yontemler: Calismaya akciger kist hidatigi olan 23 cocuk hastada toplam 28 akciger kist hidatik lezyonu dahil edildi. Hastalarin demografik bilgileri, basvuru semptomlari, akciger grafileri, bilgisayarli tomografi (BT), manyetik rezonans goruntuleme ve abdominal ultrasonografi bulgulari retrospektif olarak degerlendirildi. Radyolojik goruntulemelerde lezyon sayisi, lobar yerlesim, bronsiyal ruptur, enfeksiyon varligi, en genis boyut, duvar kalinligi, BT incelemesi olan sivi icerikli lezyonlarin sivi dansitesi degerlendirildi. Bulgular: Calismaya dahil olan 23 cocugun (kiz: 7, erkek: 16) yas ortalamasi 10.1 (yas araligi, 4-17)’di. Lezyonlarin 17’si sag, 11’i sol akcigerde izlendi. Soliter lezyon sayisi 19’du (%82.6). Lezyonlar iki hastada cift tarafli (%9.5) goruldu. Lezyonlar en sik sag akciger alt lobda yerlesim gostermekteydi (%42.9). Hastalarin 19’u (%82.6) tani aninda semptomatikti. Yirmisekiz lezyonun 19’u (%67.9) bronsiyal ruptur ve/veya sekonder enfeksiyon ile komplike olmustu. Akciger grafilerinde bronsiyal ruptur sonucu 12 lezyonda (%42.9); nilufer (n=5), meniskus (n=5) ve cift kubbe (n=2) isaretleri saptandi. BT incelemesi olan 16 hastada toplam 21 lezyon degerlendirildi. Bronsiyal ruptur ve/veya enfeksiyon bulgusu olan 16 lezyonda (%76.2) hava kabarcigi (n=6), nilufer (n=4), meniskus (n=4), cift kubbe (n=3) ve sarmal (n=1) isaretleri saptandi. Kist hidatik icin tanisal bulgunun gosterildigi lezyon sayisi BT incelemede istatistiksel anlamli olarak daha fazlaydi (p=0.031). Sekonder enfeksiyon ile komplike olan kist hidatik lezyonlarinin duvar kalinligi komplike olmayanlara gore daha kalin olculdu (p=0.028). Sonuc: Komplike akciger kist hidatigi lezyonlarinda direkt grafiler ile tanisal zorluk yasanabilir. BT goruntuleme lezyonun kistik yapisini ortaya koymada, kist hidatige ait ozel isaretlerin ve sakli alanlarda yerlesim gosteren kistlerin gosterilmesinde, komplike lezyonlarin degerlendirmesinde, cerrahi oncesi planlamada direkt grafilere ustundur. Bu nedenle akciger kist hidatiklerinin goruntulemesinde ilk tercih edilen yontem akciger grafileri olmakla birlikte komplike kistlerin BT ile degerlendirilmesi tanisal dogrulugu artirir.Objective: Lung hydatid cysts are more common in children than adults. Lung hydatid cysts may be complicated with bronchial rupture and/or secondary infection. When complicated, they can demonstrate non-specific imaging findings. We aim to present the diagnostic radiological signs of complicated and non-complicated hydatid cysts. Material and Methods: Twenty three children who had 28 lung hydatid cysts in total were enrolled in the study. Demographic information, referral symptoms, chest X-ray, computerized tomography (CT), magnetic resonance imaging and abdominal ultrasonography findings of the children were retrospectively evaluated. The number of lesions, lobar location, bronchial rupture or infection signs, maximum diameter, wall thickness, and fluid density imaged with CT were analyzed. Results: The mean age of the 23 children (girls: 7, boys: 16) was 10.1 (age range, 4-17). Seventeen lesions were observed in the right lung and 11 in left lung. The number of solitary lesions was 19 (82.6%). The lesions were bilateral

Branchial Cleft Cyst in the Differential Diagnosis of Recurrent Lymphadenitis

Lymphadenitis is a condition characterized by inflammation of one or more lymph nodes in the same region and is generally caused by infectious agents in childhood. The Epstein-Barr Virus (EBV), Cytomegalovirus (CMV), Human Immunodeficiency Virus (HIV), Human Herpes Virus 6 (HHV-6) as well as the causative agent of infectious mononucleosis, and bacterial agents such as Group A Streptococcus, S. aureus, S. epidermidis, tuberculous and non-tuberculous mycobacteria, F. tularensis, Group B Streptococcus and Yersinia are among the factors. Non-infectious etiology of cervical adenitis less frequent but includes malignancies, collagen vascular diseases, drugs, and masses simulating adenopathy. Here, a 15-year-old male patient, who presented with a complaint of recurrent swelling in the neck with no previous known disease, is presented to draw attention to a complicated branchial cleft cyst mimicking lymphadenitis.

Assessment of developmental and radiological long-term outcomeof children with surgically treated midgut volvulus

BACKGROUND/AIM The aim is to evaluate the long-term outcome of asymptomatic patients who underwent surgical correction for midgut volvulus. MATERIALS AND METHODS Seven patients managed surgically for midgut volvulus in the last 3 years were included. Demographic features, symptoms at presentation, diagnoses, surgical procedures, and complications were recorded. Patients were then contacted for follow-up and evaluation of long-term outcomes. General physical conditions, anthropometric parameters, feeding habits, and defecation histories were evaluated. Laboratory examinations were performed. Color Doppler ultrasonography (CDUS) was performed to evaluate blood flow in the superior mesenteric artery (SMA). RESULTS In total, seven patients were identified. The median age at admission was 3 days (0-90 days). Mean age at follow-up was 17 ± 2 months. Growth parameters were normal in all cases. Four patients had low levels of ferritin and transferrin saturation. One patient had microcytic anemia. Another patient had low serum zinc level. One patient who had ileal resection had a high level of steatorrhea in stool examination. In CDUS, SMA blood flow volume was low in all cases. Peak-systolic velocity and resistance index were low in all but one case. CONCLUSION Despite uneventful postoperative courses, all patients operated on for midgut volvulus showed mild laboratory changes and decreased blood flow in the SMA in long-term follow-up.

Herlyn-Werner-Wunderlich Syndrome: Sonographic and Magnetic Resonance (MR) Imaging Findings of This Rare Urogenital Anomaly

Summary Background Herlyn-Werner-Wunderlich syndrome is a rare congenital urogenital anomaly characterised by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. Children usually have progressive pelvic pain after menarche, palpable mass due to hemihaemato(metro)colpos or pelvic inflammatory disease. The diagnosis usually requires a suspicion of this rare genitourinary syndrome. Case Reports We present ultrasonography and MR imaging findings of this rare anomaly in two cases. Conclusions Early recognition of this rare syndrome can lead to an immediate, proper surgical intervention and is necessary to prevent complications and preserve future fertility. Ultrasound and MR imaging findings can collectively delineate uterine morphology, indicate the absence of ipsilateral kidney and show obstructed hemivagina.
