OBJECTIVES: Cerebral arterio-venous malformations (AVM) are considered congenital lesions, emerging as an important cause of haemorrhagic stroke in children. The potential influence of age on clinical presentation and angio-architecture have been analysed extensively in the last years. Yet, comparative studies comprising ascending age groups may be limited in their conclusions, especially when comparing young children and adults. It is the aim of this study to evaluate characteristic clinical and angiographic features of AVM within a paediatric subgroup and their correlation to age at presentation...

CASE: The classic metaphyseal lesion, or corner fracture, is considered a strong indicator of nonaccidental trauma. In the present case, the parents brought their 8-month-old boy to a community hospital after he stopped crawling on the right leg. A knee radiograph demonstrated an isolated metaphyseal lesion, which prompted concern for child abuse. The patient was transferred to the nearest academic medical center; the pediatric radiology expert in child abuse determined that the lesion was a normal variant and not the result of abuse...

BACKGROUND: No well-controlled studies have compared the long-term outcome of anterior cruciate ligament (ACL) reconstruction with hamstring tendon autograft between adolescents and adults. Increased posterior tibial slopes (PTSs) have been reported in the ACL-injured versus controls, but the effect of PTS on the outcome after reconstruction is relatively unexplored. PURPOSE: To compare the prospective longitudinal outcome of "isolated" ACL ruptures treated with anatomic endoscopic ACL reconstruction using hamstring tendon autograft over 20 years in adolescent and adult cohorts and to examine factors for repeat ACL injury...

Background: The interval between progression and death in diffuse intrinsic pontine glioma (DIPG) is usually < 6 months. However, reports of longer patient survival following radiotherapy, in the presence of radiological signs of progression, suggest that these cases may be comparable to pseudo-progression observed in adult glioblastoma. Our aim was to identify such cases and compare their multimodal MRI features with those of patients that did not present the same evolution. Methods: Multimodal MRI of 43 children treated for DIPG were retrospectively selected at four time points: baseline, after-radiotherapy, during true-progression, and at the last-visit...

Aesthetic implant restoration in the anterior maxilla is a challenge for clinicians. Alveolar ridge and surrounding gingiva deficiencies aggravates implant placement in the aesthetic area. This case report describes a technique for aesthetic single implant placement with simultaneous bone grafting and soft tissue thickening. At the time of implant surgery, allogenic (Maxgraft, Botiss Biomaterials, Germany) and xenogenic bone substitute (Cerabone, Botiss Biomaterials, Germany) was used for bone grafting, soft tissues were augmented simultaneously with collagen tissue matrix derivate membrane (Mucoderm, Botiss Biomaterials, Germany)...

BACKGROUND: Dentigerous cysts are odontogenic cysts of the jaws accounting for approximately 24% of all epithelium-lined jaw cysts. Rarely, these cysts can become extremely large causing additional symptoms, while challenging treatment. This article represents a novel approach for radiological treatment follow up of large dentigerous cysts. MATERIAL AND METHODS: Dentigerous cysts were treated by marsupialization, using dedicated obturators and enucleation of the cyst afterwards...

Multinodular and vacuolating neuronal tumors (MVNT) are low grade neuronal tumors classified in cerebral tumors based on 2016 WHO central nerve system classification. Previously, MVNTs were probably tumors incidentally determined by imaging methods, but they could not be diagnosed or they were misdiagnosed. Two cases are reported in the present study, for which radiological imaging was carried out for epilepsy in one and for headache in the other. The first case was a twenty seven years old female patient with headache complaint...

Calcifying aponeurotic fibroma is a rare, benign fibroblastic tumor that typically occurs in the palms of the hands and soles of the feet in children and adolescents. We report an unusual case of a calcifying aponeurotic fibroma with diffuse intra-articular involvement of the carpal joints in a 59-year-old female. Radiographs and computed tomography scans revealed a large lobulated soft tissue mass with multiple stippled calcifications around the carpal joints and numerous erosions of the second to fifth carpometacarpal and intercarpal joints...

The majority of neurologically symptomatic cerebrospinal fluid HIV-1 escape cases are connected with resistance-associated mutations and potentially explained by low cerebrospinal fluid antiretroviral concentrations. However, there are still significant knowledge gaps regarding the physiopathology and long-term management of neurosymptomatic viral escape. We report a case of Parkinson-like syndrome following cerebrospinal fluid HIV-1 escape in a 40-year-old female patient with an history of persistent low-level plasma viremia under treatment...

BACKGROUND AND PURPOSE: Type I and IIa dural arteriovenous fistulas (DAVFs) have a low hemorrhagic risk, but are often the cause of debilitating tinnitus that requires treatment. While Onyx® and PHIL™ (Precipitating hydrophobic injectable liquid) transarterial embolization represent the first endovascular option, there are occasional cases where performing angioplasty and stenting of the affected sinus may lead to satisfactory results. MATERIAL AND METHODS: We retrospectively analyzed four consecutive cases of patients with DAVF-induced pulsatile tinnitus secondary to type I and II DAVFs who were treated with angioplasty and stenting of the sinus only...

BACKGROUND: Abdominal lymphatic malformations (LM) are relatively rare findings in the differential diagnosis of focal abdominal lesions; however, they represent a challenge especially in younger patients. The aim of this review article is to provide up-to-date information about the different kinds of LM manifestations. In addition, related syndromes and typical imaging features to facilitate the diagnosis are discussed. RESULTS: The clinical presentation of abdominal LM is unspecific, whereby most are asymptomatic and comprise incidental findings of thin-walled cystic masses anywhere in the abdomen...

BACKGROUND: Soft tissue sarcomas are most common mesenchymal malignancies in the abdomen. Their radiologic features are often unspecific and establishing a differential diagnosis to other pathologies can be difficult. OBJECTIVES: This review presents a selection of the most common mesenchymal abdominal tumors and their imaging characteristics, as well as the associated differential diagnoses. Knowledge of fundamental pathologic, anatomic and radiologic features of these malignancies is crucial for the differential diagnosis and key in clinical decision making and subsequent selection of an appropriate therapeutic regimen...

Introduction: In the customary wisdom, it is conceded that giant-cell tumor (GCT) is a pathology of fused epiphysis, but there are literatures available to depict that even though rare bit, but it occurs in the skeletally immature patients. Here, we are presenting a rare case of GCT of the fifth metacarpal in the skeletally immature patient. Case Report: It is a case report of a 13-year-old girl with the history of swelling over her right hand for 5 months. X-ray revealed that there was an osteolytic fusiform expansible lesion...

Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycaemia in childhood (Horm Res 70:65-72, 2008; J Clin Endocr Metab 93:869-875, 2008). 18-Fluoro-L-dihydroxy-phenylalanine (18F-DOPA) positron emission tomography (PET) can detect areas of increased activity in the pancreas and may differentiate focal from diffuse CHI (J Clin Endocr Metab 93:869-875, 2008; Radiology 253:216-222, 2009). We here report the case of a girl who complained of recurrent episodes of severe hypoglycaemia despite previous partial pancreatectomy...

Purpose: The differences in performance between the cadmium-zinc-telluride (CZT) camera or collimation systems and conventional Anger single-photon emission computed tomography (A-SPECT) remain insufficient from the viewpoint of the user. We evaluated the performance of the D-SPECT (Spectrum Dynamics, Israel) system to provide more information to the cardiologist or radiological technologist about its use in the clinical field. Materials and Methods: This study evaluated the performance of the D-SPECT system in terms of energy resolution, detector sensitivity, spatial resolution, modulation transfer function (MTF), and collimator resolution in comparison with that of A-SPECT (Bright-View, Philips, Japan)...
