ABSTRACT
Background: The thymus is a central lymphoid organ that plays a vital role in the development and maturation of the immune system during childhood, the thymus appears as a bilobed triangular structure located in the anterior mediastinum. Aim and objectives: To provide radiologists a comprehensive understanding of Recognition of the variable appearance of thymic lesions and evaluation of thymic lesions on different radiological modalities like X-Rays and CT-scan for early diagnosis as well as management. Materials and methods: 10 cases of either strong suspicion or symptoms related to thymic lesion were evaluated who came to Dhiraj Hospital with different radiological modalities (X-ray, CT-scan). Results: Out of total no. of 10 patients who were diagnosed and evaluated with thymic lesion on Xrays and CT-scan are: Thymic Hyperplasia, Thymic Cyst, Thymic Lymphoma, Thymoma, Benign Teratoma, Malignant Teratoma. Conclusion: CT Imaging remains the ideal scanning modality to evaluate Radiologists play a major role in differentiating normal thymus from its variants, various thymic lesions and tumor. But common associated radiological modality used along with CT scan done is X-ray.
ABSTRACT
Group A streptococcus (GAS) rarely causes meningoencephalitis in children without risk factors. A previously healthy 8 year-old child presented with lethargy, high fever, and vomiting. The clinical course was unusual including intractable seizures, disseminated intravascular coagulation (DIC), and left hemiparesis in spite of the appropriate and timely administration of antibiotics and corticosteroids. The microbiologic studies revealed that the pathogen was susceptible to penicillin and GAS M18 strains. This case showed the importance of the GAS vaccine in addition to appropriate antibiotics.
