Pediatric stroke is a relatively rare disease, but remains one of the most common causes of death in childhood. A higher homocysteine level raises the risk of vascular disease, including stroke. In the setting of heavy alcohol consumption, the risk for all major types of strokes is increased, especially those of ischemic etiology. A 17-year-old boy who had used a large amount of cigarettes and alcohol the previous evening, presented to our clinic. Upon admission, the patient’s condition was critical, with impaired consciousness. Left-sided facial nerve paresis and left-sided hemiparesis were observed. An CT examination of the brain was performed, no gross changes were found and was indicates an urgent MRI. On MRI there was irregular configuration of the dorsal posterior limb of the internal capsule and ventrolateral parts of the right thalamus, with a focus of diffusion restriction and increased MR signal intensity on T2-weighted FLAIR sequences. MR findings are consistent with an acute ischemic stroke in the territory of the right anterior choroidal artery. No neurological deficits were detected after treatment. Alcohol intoxication and hyperhomocysteinemia are significant risk factors for ischemia. The combination of hyperhomocysteinemia with alcohol and nicotine abuse presents an even higher and more persistent risk for ischemia. Read More

Nasopharyngeal carcinoma (NPC) is a rare malignancy in the pediatric population, comprising less than 1% of all pediatric malignancies. NPC typically occurs in older children and adolescents, with the highest incidence between ages 10-19, and there may be a slight male predominance. A 14-year-old boy presented with a 2-week history of earache, hearing loss, headache, fever, neck pain, and palpable enlarged lymph nodes in the neck. Ultrasound revealed bilateral cervical lymphadenitis. Upon physical examination, the throat appeared hyperemic. Blood tests showed moderately elevated inflammatory markers. Initially, the patient was diagnosed with cervical lymphadenitis, right-sided otitis, and eustachitis. Antibiotic therapy was initiated, resulting in mild improvement; however, the primary symptoms persisted. Serological testing for Epstein-Barr virus (EBV) was negative. A contrast-enhanced CT scan was performed due to the suspicion of an abscess. The CT revealed a hypervascular mass measuring 4.3x3.3cm in the nasopharynx, extending into the parapharyngeal and retropharyngeal spaces from the right side, significantly narrowing the nasopharyngeal airway. Cervical lymphadenopathy was also noted, particularly on the right side. Given the imaging findings, a differential diagnosis was considered between lymphoma and nasopharyngeal carcinoma. A pediatric oncology consultation was obtained, and biopsies of both the retropharyngeal mass and cervical lymph nodes were performed. Histopathological analysis confirmed the diagnosis of nasopharyngeal carcinoma. Nasopharyngeal carcinoma in pediatric patients often presents with non-specific symptoms, contributing to diagnostic delays. Cervical lymphadenopathy is frequently the primary clinical finding, typically manifesting as painless enlarged neck lymph nodes. Other common symptoms include nasal obstruction, nasal discharge, and ear-related issues such as otitis media with effusion, hearing loss, or tinnitus due to eustachian tube dysfunction. In cases presenting with these symptoms, imaging with CT or MRI has an important role for early diagnosis. Read More
