Symptomatic congenital hemangiomatosis in a neonate: Imaging of a life-threatening presentation with multifocal liver involvement

Hemangiomas are the most common benign vascular neoplasms of infancy. Congenital hemangiomas proliferate in utero, and are fully formed at birth. They are usually solitary. Generalized forms are exceptional. The liver is the second most common site of hemangiomas after the skin. When >5 cutaneous hemangiomas are present, screening abdominal ultrasound is recommended. Based on the degree of liver parenchyma involvement, 3 hepatic hemangiomas’ subtypes are defined: focal, multifocal, and diffuse. Hepatic hemangiomas’ clinical presentation varies from asymptomatic to life-threatening. High output cardiac failure, consumptive coagulopathy, abdominal compartment syndrome, and liver dysfunction are possible complications. We report an unusual case of symptomatic congenital hemangiomatosis in a male infant born with innumerable generalized cutaneous hemangiomas whose screening abdominal ultrasound revealed multifocal hepatic hemangiomas with extensive mixed shunts. We aim to highlight this unique entity with severe associated complications and stress the role of imaging at initial presentation, for follow-up, and to guide therapeutic choices

Cerebral tuberculoma and convulsion in infants: A case report

Tuberculosis of the central nervous system is the second most common site after tuberculous meningitis. It represents 0.2% of intracranial expansive lesions in some Western countries compared to 10%-30% in developing countries. We report the case of an infant of 1 year and 2 months old who presented for 15 days with convulsions with asthenia, hypotonia, without fever. The clinical examination and laboratory workup were without abnormalities. His father had ongoing pulmonary tuberculosis, but the infant had no clinical or radiological signs of pulmonary tuberculosis. A brain MRI was showed multiple punctiform brain lesions, suggesting intracerebral tuberculomas in the first place, given the clinical and radiological appearance and the father's history of tuberculosis. The patient was put on anti-convulsant and antibacillary treatment. Through this case, we can see the clinical and radiological polymorphism of cerebral tuberculoma. The diagnosis of certainty remains anatomopathological. The prognosis is poor when it is detected late

Mandibular Metastasis in Neuroblastoma in a 3 Year-Old Child: A Case Report

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. Over the previous several years, only 29 cases of neuroblastoma metastasis to the mandible have been reported in the literature

Tension Hydropneumothorax Caused by a Ruptured Hydatic Cyst in the Pleural Cavity: Case Report

Hydatid disease is a zoonosis caused by a larva of the tapeworm Echinococcus. All organs can be involved, but it is frequently located in liver for adults and lung for children. The clinical features are nonspecific. Imaging findings has an important place in the diagnosis and the follow-up. Rupture is the most common complication of a hydatic cyst and has a variety of imaging findings depending on the ruptured layer, the amount of air within the cyst and the type rupture. We report the case of a 10-year-old boy presenting shortness of breath and fever among other symptoms revealing by chest X-ray and thoracic CT scan, a lung ruptured hydatic cyst to the pleural cavity causing a tension hydro-pneumothorax and a superadded infection

The white cerebellum sign: Classic but under recognized sign of brain injury

The white cerebellum sign is a concerning but uncommon radiological imaging result that is frequently seen in patients with severe, frequently irreversible anoxic-ischemic brain injury. Due to its frequent correlation with an unfavorable prognosis, radiologists must recognize this sign. We report the case of a 1 year old girl with history of epilepsy who presented with deterioration of conscious level and focal fits and brain computed tomography scan done on her revealed the white cerebellum sign

Pediatric myositis ossificans circumscripta following traumatic hip dislocation: A case report

Myositis ossificans is non-neoplastic heterotopic bone forms in skeletal muscle. We recognize 3 subtypes: fibrodysplasia ossificans progressiva, myositis ossificans with no history of trauma (nontraumatic or pseudomalignant), and circumscribed or traumatic myositis ossificans. Traumatic myositis ossificans circumscripta has not, as far as we are aware, been previously documented as a complication of traumatic hip dislocation. We present the radiological findings of a 10-year-old girl with Thevenards syndrome, whose traumatic hip dislocation was complicated by circumstantial myositis ossificans. X-rays and computed tomography scan enabled us to diagnose by the presence of mature bone in the periphery of the lesion with a smooth contour and well separated from the bone. The treatment of dislocation and complication was nonoperatively

Posterior Reversible Encephalopathy Syndrome: A Complication of Acute Renal Failure in a Child

Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological entity occurring during several conditions and more frequently in those associated with severe hypertension. The diagnostic approach is possible by considering the clinical context and MRI data, where white matter abnormalities are observed predominantly in the parietal and occipital territories secondary to the formation of a vasogenic edema. The evolution is characterized by a reversibility of the lesions in case of early diagnosis and management. The authors report a case of reversible posterior encephalopathy in a 12-year-old child who presented with a status epilepticus, revealing an acute renal failure

A rare case of Ewing's sarcoma of the maxillary sinus

Ewing's sarcoma is generally an aggressive, poorly differentiated bone and soft tissue tumor affecting children and young adults, it accounts for 4%-6% of all primary bone tumors and primary facial locations occur in only 1%-4% of all cases, primarily in the mandible and calvaria. Involvement of the paranasal sinuses is rare. Here we report the case of an 11-year-old girl with no medical, surgical, or traumatic history, who presented for 1 month and progressive evolution of swelling of the left cheek, associated with pain, nasal obstruction, rhinorrhea, and a slight weight loss not quantified. A craniofacial computed tomography (CT) scan showed a mixed lytic and condensing lesional tissue process centered on the left maxillary sinus, heterogeneously enhanced after contrast injection, lysing the walls of the sinus extended to the homolateral nasal cavity and slightly infiltrating the adjacent soft tissues. An incisional biopsy was performed and the pathological study proved that it was Ewing's sarcoma. She was put on neoadjuvant chemotherapy using 6 courses of vincristine, doxorubicin, ifosfamide, etoposide which resulted in a partial regression of the tumor size by 50%. Then the patient was put on combined chemotherapy and radiotherapy. A follow-up CT scan after 6 courses of vincristine, actinomycin, cyclophosphamide, and 17 sessions of radiotherapy showed lesion stability. Maxillary Ewing's sarcoma is a rare and aggressive tumor. Therefore, early diagnosis, combination therapy, and long-term follow-up are suggested in such cases to improve the survival rate

Clinical and Radiological Features in Poland Syndrome: Report of 3 Cases and Review of Literature

Poland syndrome is indeed a rare congenital malformation that can present with various degrees of thoracic and homolateral upper limb anomalies. The classic features of Poland syndrome include agenesis or hypoplasia of the sternocostal head of the pectoralis major muscle, hypoplasia of the nipple, absence of subcutaneous fat, multiple rib abnormalities, and sometimes Sprengel deformity (elevation of the scapula). Additionally, ipsilateral symbrachydactyly (combination of “short fingers” with cutaneous syndactyly [fused fingers]) may also be observed. However, it’s important to note that not all of these findings are always present in every patient, and the combination of features can vary greatly. Surgical treatment for Poland syndrome primarily focuses on improving pulmonary functions resulting from severe thoracic deformities. However, it is frequently performed with the additional goal of enhancing cosmetic appearance. In recent times, the use of adipose-derived mesenchymal stem cells and fat transfer has shown promising results for correcting chest defects and breast augmentation. In our study, we present a series of 3 cases that were referred to our institution due to thoracic deformities associated with Poland syndrome

Late presentation of gastric duplication cyst in pediatric patient: Lessons learned

Gastrointestinal duplication is an infrequent congenital disorder characterized by the presence of a muscular layer covered by mucosa. Gastric duplication cysts account for approximately 2%-9% of all gastrointestinal duplication cysts. The typical clinical presentation often includes symptoms such as epigastric pain, vomiting, and the presence of a palpable abdominal mass. However, these symptoms can overlap with more common conditions. Diagnostic confirmation usually necessitates additional imaging studies, and surgical intervention is the recommended treatment approach. In this case report, we present the case of a 9-year-old girl who presented with chronic abdominal pain and vomiting. Following a comprehensive evaluation, including a CT scan and various diagnostic tests, a diagnosis of gastric duplication cyst was established. The patient subsequently underwent a laparotomy procedure, during which the cyst was completely excised. Follow-up visits indicated an uneventful recovery, with complete resolution of all symptoms. The aim of this work is to report on the clinico-radiological aspects of gastric duplication cysts and their surgical treatment
