Abdominal mass child

BACKGROUND: Congenital infantile fibrosarcoma (CIF) and congenital hemangioma (CH) have similarities on prenatal ultrasound and are rare. CASE SUMMARY: We report 3 cases of fetuses with superficial hypervascular tumors, confirmed by postnatal pathology as CIF (1 case) and CH (2 cases, including 1 in a twin fetus). In Case 1, a mass with a rich blood supply in the fetal axilla was discovered by prenatal ultrasound at 28+0 wk of gestation. The postpartum pathological diagnosis was CIF, the mass was surgically removed, and the prognosis of the child was good...

A previously healthy but overweight (body mass index (BMI) of 24.4) adolescent boy presented with fever and significant right-sided abdominal pain. An abdominal ultrasound scan revealed an omental infarction (OI), which was treated conservatively. OI has been described in overweight teenage children with abdominal trauma but can be missed if not considered. A missed diagnosis could result in an unnecessary laparotomy or laparoscopic surgery. Although CT is the gold standard for diagnosis, ultrasonography is an effective approach to identifying OI in children...

BACKGROUND: Common complications following kidney transplant include infection, rejection, and malignancy. Multiple masses in a transplanted kidney raise suspicion for malignancy. CASE PRESENTATION: A 20-year-old female with chronic kidney disease stage 3 T presented with graft tenderness, acute kidney injury, and heterogeneous masses in her transplanted kidney visualized via ultrasound. She was inadequately treated for chlamydia 1 month prior and retested positive upon admission...

BACKGROUND: The ratio of triglycerides-to-high-density lipoprotein cholesterol (TG/HDL-C) is considered a robust biomarker of metabolic syndrome (MetS) and is associated with several diseases, including type 2 diabetes mellitus (T2DM) and hypertension (HTN). This study examined the independent association of adiposity and fitness with the TG/HDL-C ratio. MATERIALS AND METHODS: This is a cross-sectional study comprising 403 (201 girls) Nigerian adolescents aged 11-19 years...

BACKGROUND: Studies in adults have shown that low baseline muscle mass at intensive care unit (ICU) admission was associated with poor clinical outcomes. However, no information on the relationship between baseline muscle quality or mass and clinical outcomes in critically ill children was found. METHODS: 3775 children were admitted to the pediatric ICU (PICU), 262 were eligible for inclusion. Abdominal computed tomography was performed to assess baseline skeletal muscle mass and quality...

Three-year-old boy who presented with colicky abdominal pain, diarrhoea and vomiting was investigated with computed tomography which revealed a mass in the peripancreatic region. An imaging possibility of duodenal intramural hematoma was considered after reassessment with ultrasound which was subsequently confirmed by magnetic resonance imaging. The development of a spontaneous duodenal hematoma lead to further evaluation of the patient and revealed X linked hyper IgM syndrome.

Primary sarcoma of the ovary is extremely rare. There are inadequate data in the literature regarding ovarian sarcoma in the pediatric age group. We report a case of an 8-year-old girl presenting with large abdominal mass and cachexia. Raised alpha-fetoprotein levels suggested germ cell tumor. Tru-cut biopsy histopathological report suggested a spindle cell tumor. The IHC staining suggested non rhabdomyosarcoma. As tumour was large and ovarian pediatric non rhabdomyosarcoma was not reported in the literature, we started on rhabdomyosarcoma neoadjuant regimen...

INTRODUCTION: Polycystic liver disease (PCLD) is a genetic disorder characterized by the growth of >10 cysts in the liver. PCLD is associated with polycystic kidney disease (PKD) in 80-90%of cases (Kothadia et al., 2023 [1]). PCLD can occur in isolation though rarely in children. We present a case report of a child with symptomatic isolated PCLD. CASE PRESENTATION: A 23-month old female child presented with a 17-month history of gradual increase in abdominal mass...

INTRODUCTION AND IMPORTANCE: Pediatric hepatic tumors present diagnostic challenges due to diverse clinical presentations and limited patient communication. Elevated serum alpha-fetoprotein (AFP) levels, often associated with hepatoblastoma, can occur in various hepatic conditions, adding complexity to diagnosis. This report emphasizes the importance of comprehensive assessment and integrated interpretation in such cases. CASE PRESENTATION: We present a rare case of a 1-year-old female child with abdominal swelling and hepatomegaly...

This case report describes a previously healthy pediatric patient with acute onset of abdominal pain and distention who was found to have an epigastric mass on physical examination. Point-of-care ultrasound (POCUS) demonstrated a large gastric mass with ultrasonographic features consistent with a trichobezoar. After POCUS was performed, trichophagia was confirmed on history, and the patient went to the operating room for removal of a large trichobezoar. We conclude POCUS may be helpful for evaluation of epigastric masses and diagnosis of gastric trichobezoars...

This case study delves into the unique presentation of bezoars in a 14-year-old autistic female who exhibited chronic diarrhea and abdominal pain. While trichobezoars, masses formed from ingested hair, are rare, they are predominantly seen in young females and are associated with psychiatric conditions. Through rigorous diagnostic procedures, including a computed tomography imaging of the abdomen and pelvis (CTAP) scan, fecal impaction, and multiple bezoars, including hair and non-biological items, were identified...

The differential diagnosis for an abdominal mass in a 2-year-old child is broad and includes lesions of renal, hepatic, gastrointestinal, adrenal, and lymphatic origins. Of these, Wilms' tumor and neuroblastoma are the most common tumors, where Wilms' tumor represents about 92% of renal masses in children. Non-Wilms' renal tumors, rhabdoid tumors, and clear cell sarcoma of the kidney (CCSK) are uncommon. CCSK constitutes approximately 3% of all malignant renal tumors in childhood. In this report, we present a child presenting with a huge renal mass consistent with Wilms' tumor on computed tomography and initial biopsy...

OBJECTIVES: Intussusception is one of the most common surgical emergencies in children. We aimed to analyze the current clinical characteristics of intussusception. METHODS: We retrospectively reviewed 209 children diagnosed with intussusception, who were admitted to our hospital between January 2009 and August 2022. We grouped the patients according to symptom duration (before and after 12 hours and before and after 24 hours) and age (younger and older than 1 year, and younger and older than 2 years)...

Pheochromocytomas are catecholamine-producing tumors derived from the adrenomedullary chromaffin cells. The presentation is a classic triad of episodic headaches, sweating, and tachycardia. Hypertensive crisis can occur due to profuse catecholamine excess. Unusual manifestations mimicking cardiogenic shock, arrhythmia, and myocarditis have been rarely reported in children. We present a case with uncommon manifestations of pheochromocytoma in a child, including the episodes of exercised-induced presyncope with QT prolongation, and subsequently cardiogenic shock due to fulminant myocarditis...

Neuroblastomas commonly metastasize to the cranium and orbit, although other facial bones were less implicated. In this report we present a 3 years old child with metastatic neuroblastoma to the mandible that presented with swollen right jaw. The first assessment of the head with computed tomography revealed soft tissue mass with permeative lytic changes of the osseous structures centered on the right mandible, as well as osteo-meningitis metastases. These masses were proven to be metastatic lesions from intra-abdominal neuroblastoma of the right adrenal gland...

The need for cholecystectomy during pediatric age has significantly increased in the last two decades. As biliary pathology increases, the probability of complicated cholecystectomies increases too. The aim of this article is to analyze our experience with difficult laparoscopic pediatric cholecystectomy, focusing on the importance of an accurate pre-operative imaging study. We retrospectively analyzed all patients affected by cholelithiasis who underwent laparoscopic cholecystectomy at the Pediatric Surgery Department of San Camillo Forlanini hospital of Rome and Santa Maria alle Scotte University Hospital of Siena from 2017 to 2022...

BACKGROUND: Wilms tumor (WT) is the most frequent renal tumor in children. The SIOP-UMBRELLA Guidelines allow for nephron-sparing surgery (NSS) in syndromic patients, as well as in cases of small (<300 mL) non-syndromic unilateral WTs, without lymph node involvement, and with a substantial expected remnant renal function, following neoadjuvant chemotherapy. We present a case of prechemotherapy transperitoneal robot-assisted partial nephrectomy (RAPN) for a unilateral, non-syndromic Wilms tumor...

BACKGROUND: Sclerosing angiomatoid nodular transformation of the spleen is a relatively rare benign vascular lesion in both adult and pediatric age groups with unclear etiopathogenesis and variable clinical presentations. Many benign and also malignant splenic masses could mimic sclerosing angiomatoid nodular transformation, both clinically and radiologically. Herein, we report our experience with a case of sclerosing angiomatoid nodular transformation in a 3-year-old girl. CASE REPORT: A 3-year-old Iranian girl presented with abdominal pain, back pain, and constipation for 2 weeks...

BACKGROUND: Body composition between prepubertal children and adolescents varies, and it is unclear how physical activity and sedentary behaviour affect adolescent body composition. OBJECTIVES: This study aimed to examine the associations of physical activity and screen time with overall and specific fat depots in the general adolescent population. METHODS: In a population-based prospective cohort study, among 3258 adolescents aged 13 years, physical activity and screen time were assessed via self-report questionnaires...

BACKGROUND: Disadvantaged neighborhood environments are a source of chronic stress which undermines optimal adolescent health. This study investigated relationships between the neighborhood social environment, specifically, chronic stress exposures, adiposity, and cardiometabolic disease risk factors among 288 Louisiana adolescents aged 10 to 16 years. METHODS: This cross-sectional study utilized baseline data from the Translational Investigation of Growth and Everyday Routines in Kids (TIGER Kids) study...
