Lymphomatoid Granulomatosis Involving the Lung and Brain in a Child: A Case Report
황숙민,유소영,김지혜,전태연,오세린,조은윤,제보경 대한영상의학회 2021 대한영상의학회지 Vol.82 No.1
Lymphomatoid granulomatosis (LG) is a rare B-cell type angiocentric lymphoproliferative disease that can progress to extranodal lymphoma with high mortality. It most commonly affects the lungs, although extrapulmonary systems, including the brain and skin, can also be involved. LG in pediatric patients has been very rarely reported in the literature with limited imaging features. Herein, we report a pediatric case of LG involving the lung and brain with characteristic imaging findings.
상장간막동맥증후군처럼 보이는 위날문막힘이 있는 소아의 호산구성 위장관염

Eosinophilic gastroenteritis (EGE) is known to have a low incidence among the pediatric population, but it can result in serious complications, such as gastric outlet obstruction. In previously published EGE cases with the obstruction in adults, surgeries were often performed. In this report, we present a 14-year-old girl who came to our facility with severe abdominal pain and vomiting. On the initial abdominal physical examination, diffuse tenderness and severe epigastric pain were noted. Computed tomography scan of the abdomen showed the findings of superior mesenteric artery (SMA) syndrome. However, she had no history of recent weight loss, and the medical history was inconsistent with SMA syndrome. We planned upper gastrointestinal series with barium, and then verified gastric outlet obstruction. We performed esophagogastroduodenoscopy and obtained a final diagnosis of EGE through mucosal biopsy specimen. Corticosteroids and anti-inflammatory medications were administered. Dietary modification and education were done as well. The symptoms resolved, and the follow-up esophagogastroduodenoscopy and ultrasonography showed improvements in the obstruction. Our case emphasizes that gastric outlet obstruction due to EGE must be carefully differentiated from SMA syndrome because of their similarities in clinical features and radiologic images. In doing so, we can avoid surgical intervention and perform medical/dietary treatment for gastric outlet obstruction. .
Ileocolic Intussusception Accompanied with Inflamed Appendix: 2 Case Reports
이형주,황숙민,원영주,우지영,이건희,홍민의 대한영상의학회 2021 대한영상의학회지 Vol.82 No.3
Intussusception and acute appendicitis are common emergency conditions in children. They should be promptly differentiated in pediatric patients presenting with suggestive symptoms. However, both diseases may occur simultaneously. Herein, we present two cases of intussusception of the appendix accompanied with appendicitis.
Value of Repeat Brain MRI in Children with Focal Epilepsy and Negative Findings on Initial MRI

Objective: To evaluate the value of repeat brain magnetic resonance imaging (MRI) in identifying potential epileptogenic lesions in children with initial MRI-negative focal epilepsy. Materials and Methods: Our Institutional Review Board approved this retrospective study and waived the requirement for informed consent. During a 15-year period, 257 children (148 boys and 109 girls) with initial MRI-negative focal epilepsy were included. After re-evaluating both initial and repeat MRIs, positive results at repeat MRI were classified into potential epileptogenic lesions (malformation of cortical development and hippocampal sclerosis) and other abnormalities. Contributing factors for improved lesion conspicuity of the initially overlooked potential epileptogenic lesions were analyzed and classified into lesion factors and imaging factors. Results: Repeat MRI was positive in 21% (55/257) and negative in 79% cases (202/257). Of the positive results, potential epileptogenic lesions comprised 49% (27/55) and other abnormalities comprised 11% of the cases (28/257). Potential epileptogenic lesions included focal cortical dysplasia (n = 11), hippocampal sclerosis (n = 10), polymicrogyria (n = 2), heterotopic gray matter (n = 2), microlissencephaly (n = 1), and cortical tumor (n = 1). Of these, seven patients underwent surgical resection. Contributing factors for new diagnoses were classified as imaging factors alone (n = 6), lesion factors alone (n = 2), both (n = 18), and neither (n = 1). Conclusion: Repeat MRI revealed positive results in 21% of the children with initial MRI-negative focal epilepsy, with 50% of the positive results considered as potential epileptogenic lesions. Enhanced MRI techniques or considering the chronological changes of lesions on MRI may improve the diagnostic yield for identification of potential epileptogenic lesions on repeat MRI.
MRI Findings of Intercostal Schwannoma: A Case Report

Intercostal schwannomas are uncommon, encapsulated neoplasms that originate in nerve sheaths of intercostal nerves. They account for less than 10% of primary neural tumors of the chest wall. Herein, we report a pathologically confirmed case of intercostal schwannoma with typical magnetic resonance imaging findings.

Adenosquamous carcinomas of the duodenum are extremely rare neoplasms in which both glandular and squamous elements demonstrate malignant characteristics. Few cases of adenosquamous carcinoma involving the second or third segment of the duodenum have been reported in the literature. Herein, we report the first case of adenosquamous carcinoma of the bulb of the duodenum that mimicked subepithelial tumor on computed tomography in a 59-year-old man.
