Radiologic appearance of a bronchial granular cell tumor with secondary obstructive changes.

Bronchial granular cell tumor is a rare neoplasm. This report describes a 16-year-old female with this tumor in the right upper lobe. An ill-defined mass with peripheral infiltration was recognized on a chest radiograph.

A case of dermoid cyst of the floor of the mouth: ultrasonography was more useful than computed tomography and magnetic resonance imaging in the preoperative diagnosis.

Dermoid cysts are rare in the floor of the mouth. This report presents a case of dermoid cyst (dermoid type) of the floor of the mouth in a 21-year-old man. The preliminary preoperative assessment was made by using three modalities: computed tomography (CT), magnetic resonance imaging (MRI), and ultrasonography (US).

Quantitative MDCT analysis of pulmonary solid nodules using three parameters.

Purpose: The purpose of this prospective study was to perform quantitative multidetector computed tomography (MDCT) analysis of pulmonary solid nodules using three parameters (long-short ratio, compactness, and intranodular CT number) and to evaluate the usefulness of each parameter in the differentiation of the nodules.

Materials And Methods: Seventy solitary pulmonary nodules with a long axis length of 5-30 mm were examined using one multidetector CT (MDCT) system and one three-dimensional (3D) system, and the findings regarding the three parameters were statistically analyzed among five diseases (hamartoma, organizing pneumonia, adenocarcinoma, squamous cell carcinoma, and metastasis).

Results: The long-short ratio of the pulmonary nodule showed no significant differences among five diseases.

A symptomatic child with ceftriaxone-associated biliary pseudolithiasis.

A 5-year-old boy who had pneumonia was treated in a neighboring hospital. Ceftriaxone was administrated 2 g/day divided into two equal intravenous doses. After 1 week of ceftriaxone therapy, the patient developed abdominal pain.

Sonographic assessment of thyroglossal duct cysts in children.

Objective: The purpose of this study was to clarify the sonographic features of thyroglossal duct cysts (TDCs) in children. We also investigated how the presence of inflammation influences the sonographic appearance.

Methods: We reviewed the sonograms from 36 children (0.

Pharyngitis of infectious mononucleosis: computed tomography findings.

Two women presented with sore throat and fever. Their symptoms were not alleviated by antibiotics. Cervical computed tomography (CT) with contrast enhancement demonstrated enlargement of predominant posterior cervical lymph nodes and streaky heterogeneous tonsils with interspersed low attenuation.
