BACKGROUND: Ewing sarcoma/primitive neuroectodermal tumor is a family of highly malignant proliferation of neuroectodermal origin, most often skeletal, adrenal localization is extremely rare. Only few cases have been reported in the literature. Classical management includes radical surgery with adjuvant chemotherapy or radiotherapy or both. This case report is the only one where recurrence was surgically removed, and it confirms the importance of adjuvant treatment, and the efficacy of neoadjuvant chemotherapy...

Campomelic dysplasia is an autosomal dominant skeletal dysplasia caused by heterozygous SOX9 mutations. Most patients are sporadic due to a de novo mutation. Familial campomelic dysplasia is very rare. We report on a familial campomelic dysplasia caused by maternal germinal mosaicism. Two siblings showed the classic campomelic dysplasia phenotype with a novel SOX9 mutation (NM_000346.3: c.441delC, p.(Asn147Lysfs*36)). Radiological examination of the mother showed mild skeletal changes. Then, her somatic mosaicism of the mutation was ascertained...

BACKGROUND: The distal tibia is a common location for the classic metaphyseal lesion (CML). Prior radiologic-pathologic studies have suggested a tendency for medial, as opposed to lateral, cortical injury with the CML, but there has been no formal study of the geographic distribution of this strong indicator of abuse. OBJECTIVE: This study compares medial versus lateral cortical involvement of distal tibial CMLs in a clinical cohort of infants with suspected abuse...

Diagnostic errors in radiology are frequent and can cause severe patient harm. Despite large performance differences between radiologists and non-radiology physicians, the latter often interpret medical images because electronic health records make images available throughout the hospital. Some people argue that non-radiologists should not diagnose medical images at all, and that medical school should focus on teaching ordering skills instead of image interpretation skills. We agree that teaching ordering skills is crucial as most physicians will need to order medical images in their professional life...

In dentistry, methods for determining age and the degree of dental and skeletal development play an important role, in particular in the assessment of developmental disorders of the dentition as well as in the planning of orthodontic interventions. Dentistry is also important in the field of forensics due to the possibility of age determination based on the dentition. In addition to anthropometric and morphologic methods, numerous biochemical, histologic, radiologic, and radiation-free imaging methods exist to determine the chronologic, but also dental and skeletal age of a person or a patient...

BACKGROUND: Metastatic tumors to bone constitute the majority of bone malignancies. The site of metastasis to bone and the prognosis depend chiefly on the primary tumor. Despite all the advances in diagnostic techniques, identifying the primary tumor has not improved significantly. METHODS: A total of 576 cases (Lebanon; n = 306, Pakistan; n = 270) presenting with microscopic evidence of metastasis to bone were reviewed between 1996 and 2016. Clinical and radiologic data were recorded...

BACKGROUND: Dyssegmental dysplasia Silverman-Handmaker (DDSH; MIM 224410) type is an extremely rare skeletal dysplasia caused by functional null mutations in the perlecan gene. Less than forty cases are reported in the literature, of which only four were prenatally detected. METHODS: We report on a dizygotic twin pregnancy from consanguineous parents for which one of the twins presented prenatally with severe micromelia, limb bowing and scoliosis, and postnatally with clinical and radiological features compatible with a diagnosis of dyssegmental dysplasia...

Nail-Patella syndrome (NPS) is an inherited disease with characteristic nail, limb, and renal anomalies. While almost all patients manifest classical skeletal and nail abnormalities, renal involvement is seen in only 40% of patients. Asymptomatic proteinuria is the most common renal presentation. Although a substantial number of patients can progress to nephrotic range proteinuria, development of end-stage kidney disease is rare. Pathological abnormalities are appreciable only by electron microscopy. Our patient who had not been diagnosed with NPS previously presented with new-onset proteinuria during the second trimester of her first pregnancy...

Study Design: Retrospective radiological review. Purpose: To quantify the effect of sitting vs supine lumbar spine magnetic resonance imaging (MRI) and change in anterior displacement of the psoas muscle from L1-L2 to L4-L5 discs. Overview of Literature: Controversy exists in determining patient suitability for lateral lumbar interbody fusion (LLIF) based on psoas morphology. The effect of posture on psoas morphology has not previously been studied; however, lumbar MRI may be performed in sitting or supine positions...

BACKGROUND: Sleeve gastrectomy (SG) has become the primary procedure for many bariatric teams and staple-line leak represents its most feared complication. Sarcopenic obesity combines the risks of obesity and depleted lean mass leading possibly to an inferior surgical outcome after abdominal surgery. OBJECTIVES: The aim of this study was to evaluate the existence of a potential link between radiologically determined sarcopenic obesity and staple-line leak risk after SG...

The archaeological excavations carried out in 1999 in the Collatina necropolis of the Roman Imperial Age (1st-3rd centuries AD) (Rome, Italy) discovered the skeletal remains of two adult males with evidence of paranasal lesions. Both individuals showed postmortem damage in the frontal bone, through which it was possible to macroscopically detect an oblong new bone formation. In both specimens, radiological examination of the defects' morphology showed new pediculated-based bone formations. Radiology also confirmed the presence of benign osseous masses arising from the right frontal sinus and interpreted as osteomata...

Monoarticular tuberculosis of the wrist is a rare presentation of primary tuberculosis, being more common skeletal forms involving the spine. Extraspinal tuberculous osteomyelitis is rare and comprises only 2 to 3% of all cases of osteoarticular Mycobacterium tuberculosis infections. We present a case of a 49 years old female patient, who worked as an hospital cleaning employed without other comorbidity. After a low energy injury of the wrist she suffered pain syndrome diagnosticated as a flexor tendinopathy, managed with nonsteroidal antiinflammatory drugs and physical therapy...

The diaphragm is an unique skeletal muscle separating the thoracic and abdominal cavities with a primary function of enabling respiration. When abnormal, whether by congenital or acquired means, the consequences for patients can be severe. Abnormalities that affect the diaphragm are often first detected on chest radiographs as an alteration in position or shape. Cross-sectional imaging studies, primarily computed tomography (CT) and occasionally magnetic resonance imaging (MRI), can depict structural defects, intrinsic and adjacent pathology in greater detail...

Breast carcinoma with osteoclastic giant cells (OGCs) is a rare entity characterized by an admixture of giant cells and malignant epithelial cells within an inflammatory and vascular stroma. Denosumab is a monoclonal antibody that targets the pathway for osteoclast formation and activation, indicated for the prevention of skeletal-related events in patients with bone metastases, as well as for the treatment of giant cell tumor of bone. We report a patient who presented with aggressive bone recurrence of breast cancer 12 years after her original diagnosis, showing a transformed histology that included multinucleated OGCs, and that was refractory to traditional therapy...

BACKGROUND: Although a valve-like mechanism has been proposed for expansion of spinal extradural arachnoid cysts (SEACs), the detailed mechanism remains unclear. Moreover, closure of the communication site is essential during surgery, but the method to identify the communication site remains unclear. The aim of this study was to determine the detailed mechanism of expanding SEACs through retrospective analysis of SEAC cases undergoing surgery and to elucidate the characteristics of the communication sites...

Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations...
