In the second part of this exhibit, congenital bone anomalies of the lower extremity will be identified and reviewed. Through this exhibit, the reader will be able to: 1. Define the most common entities encompassing congenital lower extremity bone anomalies based on classic clinical presentation and demographics. 2. Highlight key multi-modality imaging characteristics to accurately differentiate between the various congenital bone anomalies of the lower extremity. Read More

Focal nodular hyperplasia (FNH) is a benign lesion. Gadoxetate disodium (Eovist), a hepatocyte specific contrast agent, is becoming more widely used in pediatric MR imaging. FNH is composed of hepatocytes and should demonstrate homogeneous enhancement on the hepatobiliary phase of imaging; however, in clinical practice a variety of enhancement patterns have been observed. The purpose of this study is to document the features of FNH on hepatobiliary phase MRI in pediatric patients. Read More

Pediatric calvarial lesions are uncommon and range in significance from incidental developmental variants to life-threatening disorders. Lesions often come to attention as nonspecific palpable abnormalities and initial imaging work-up may vary. A structured approach is therefore critical to differentiate between non-aggressive and aggressive lesions, between lesions germane to bone and those with secondary calvarial involvement, as well as between truly localized lesions and focal manifestations of multifocal or systemic disease. Lesions with a characteristic imaging appearance include atretic cephalocele, occipital encephalocele, parietal foramina, calcified cephalohematoma, dermoid cyst and fibrous dysplasia. Other lesions may require further imaging of other body regions in conjunction with clinical features and laboratory tests including pathology, laboratory markers and genetic testing. These include chronic non-bacterial osteomyelitis, Langerhans cell histiocytosis, sarcoidosis and neoplastic lesions such as Ewing sarcoma, osteosarcoma, lymphoma and metastasis. The aim of this pictorial essay is to illustrate the multi-modality imaging appearance of the most common focal pediatric calvarial lesions to aid in narrowing the differential diagnosis and to direct subspecialty referral where appropriate.

During the past one year we encountered three previously healthy children ages 10,8 and 2 years respectively who presented with localized colicky abdominal pain of few days duration. All three patients had eosinophilia ,one of whom had an associated fever and a high white blood cell count. Firm tender masses were palpated in the right side of their abdomens.
Their abdominal ultrasounds showed well defined hypoechoic masses with central components of gaseous artefacts, indicating bowel loop involvement. Computed tomography then done, showed aneurysmal dilatation with mural circumferential thickening of the ascending colon. The affected bowel loops were attenuating, showed perilesional fat stranding and multiple mesenteric lymph nodes some of which showed signs of necrosis. Neoplastic and infectious causes were therefore entertained.
Gastrointestinal lymphoma would show such aneuryusmal dilatation with mural thickening. However 50% of these affects the ileo-caecal segment. Moreover, our patients did not exhibit any symptoms or laboratory findings suggestive of a malignant process.
The presence of necrotic lymph nodes geared towards tuberculosis. However, again this is most commonly seen in the ileocecal segment. Since the patients were not septic and had high eosinophil count, atypical infections were considered. Having come across some reported cases of basidobolomycosis from the Arabian peninsula we therefore put this diagnosis at the top of our differentials.
The patients underwent hemicolectomies and were all confirmed histologically to have characteristic features of basidobolomycosis. In retrospective review of the patients' files we did observe that they were all from the coastal region of Oman.
The main objectives of this report is to draw the attention that such rare fungal infections are not uncommon in our country and the region and to enlighten the importance of a broad systematic approach when considering the various aetiological causes of focal bowel thickening including rare diseases that may be endemic in certain areas.

Detection of focal cortical dysplasias (FCDs) can be challenging. Our aim was to evaluate quantitative contrast differences between FCDs and the mirror-location normal gray matter, and the effect thereof on the ease of detection by radiologists.
