Single fetal demise in monochorionic twins: How to predict cerebral injury in the survivor co-twin?

Introduction: The aims of the study were to evaluate perinatal outcome in monochorionic (MC) twins complicated with single intrauterine fetal death, spontaneously vs after fetal therapy, and to assess antenatal events that increase the risk of cerebral injury.

Material And Methods: Historical cohort study of MC pregnancies with single intrauterine fetal death diagnosed or referred to a tertiary referral hospital (2012-2020). Adverse perinatal outcome included termination of pregnancy, perinatal death, abnormal fetal or neonatal neuroimaging and abnormal neurological development.

Fibrovascular Tumor-Like Lesions of the Facial Nerve.

Background: Facial nerve tumors (FNTs) are relatively rare benign lesions that arise from any segment of the facial nerve (FN). About half of all patients present with FN dysfunction, mainly long-standing or progressive facial paralysis. Diagnosis of an FNT is usually based on radiological imaging and confirmed by histological study.

A magnetic resonance imaging diagnostic dilemma: diffuse infiltrating retinoblastoma versus Coats' disease.

A 6-year-old boy presented with neovascular glaucoma secondary to total retinal detachment. Magnetic resonance imaging findings suggested diffuse infiltrating retinoblastoma. Enucleation was subsequently performed and led to a final histopathological diagnosis of advanced Coats' disease.

Meningeal relapse by follicular lymphoma as a single mass.

Follicular lymphoma is the second most common lymphoma throughout the world. Its course is usually indolent. Affection of Central Nervous System by a follicular lymphoma is usually as primary disease, and secondary affection is usually due to high-grade transformation.

Pancreatic cystosis in children and young adults with cystic fibrosis: sonographic, CT, and MRI findings.

Objective: We sought to analyze the sonographic, CT, and MRI findings of pancreatic cystosis, an unusual form of pancreatic involvement in cystic fibrosis (CF) that is characterized by macrocysts of different sizes distributed throughout the gland.

Conclusion: CT and MRI essentially confirmed the findings of sonography in all cases, providing no relevant additional information about the nature, internal structure, or content of the cysts. When pancreatic macrocysts are clearly shown on sonography in asymptomatic patients with CF, no additional imaging is warranted.
