Quantitative and qualitative comparison of standard-dose and low-dose pediatric head computed tomography: a retrospective study assessing the effect of adaptive statistical iterative reconstruction.

Objectives: Our aim was to assess the effect of adaptive statistical iterative reconstruction (ASIR) on pediatric head computed tomography (CT) examinations.

Methods: We retrospectively reviewed 305 pediatric head CT examinations. The study population consisted of standard dose (STD, n = 152) examinations reconstructed with filtered back projection and low dose (LD, n = 153) examinations reconstructed with 30% (LD30) and 0% (LD0) ASIR.

An unusual presentation of muscle-eye-brain disease: severe eye abnormalities with mild muscle and brain involvement.

Muscle-eye-brain disease (MEB) is characterised by congenital muscular dystrophy, structural brain malformations and eye abnormalities. We report a MEB case whose presenting sign was congenital blindness. She was investigated primarily for eye abnormalities at onset.

Late relapsing Wilms tumor with rhabdomyomatous differentiation.

The authors report a patient with abdominally relapsed Wilms tumor with rhabdomyomatous differentiation leading to renal failure and death 9 years after the initial diagnosis. The patient was treated with intensive chemotherapy because of inoperable tumor but no response was obtained. The prognosis of children with Wilms tumor relapsed in abdomen and in previously irradiated fields is poor and intensive chemotherapy protocols for differentiated tumors after chemotherapy will increase the risk of complications without obvious benefit.

[Case report: Complex composite odontoma: Plain radiography and computed tomography findings].

Complex composite odontoma is a rare benign odontogenic hamartoma seen in association with a primary tooth. Although it is seen most frequently between 10-19 years of age, here we present a lesion of unusual size in the mandible of a 6-year-old boy and report its clinical, radiographic, CT and histologic findings. Also, we discuss the value of three dimensional images.

Conservative treatment for small intestinal intussusception associated with Henoch-Schönlein's purpura.

Purpose: Emergency laparotomy is generally considered the appropriate course of action for small bowel intussusception associated with Henoch-Schönlein's purpura (HSP). In this paper, we define a conservative approach after witnessing spontaneous reduction of ileoileal invagination at laparotomy in a patient with HSP who had been on steroid therapy for renal involvement.

Methods: HSP was diagnosed by the appearance of a purpuric rash without thrombocytopenia.

Solitary Plasmacytoma of Tibia in a 29-Year-Old Woman.

Solitary plasmacytoma of the bone is a plasma cell tumor characterized by a single bone lesion with no evidence of myeloma elsewhere, including fewer than 5% plasma cells in the bone marrow. Although median age is about 14 years younger than that of patients with multiple myeloma, both diseases are extremely uncommon under 30 years of age. Solitary plasmacytoma of bone seem to have a prediction to occur in the axial skeleton, particularly in a vertebra and long bones are rarely affected.
