Pictorial essay: Orbital tuberculosis

Tuberculosis of the orbit is rare, even in places where tuberculosis is endemic. The disease may involve soft tissue, the lacrimal gland, or the periosteum or bones of the orbital wall. Intracranial extension, in the form of extradural abscess, and infratemporal fossa extension has been described. This pictorial essay illustrates the imaging findings of nine histopathologically confirmed cases of orbital tuberculosis. All these patients responded to antituberculous treatment.

Xanthogranulomatous cholecystitis: sonographic and CT features and differentiation from gallbladder carcinoma: a pictorial essay

The imaging features of xanthogranulomatous cholecystitis closely resemble those of gallbladder carcinoma, especially those of the wall-thickening variety. There is an overlap between these two conditions with respect to the clinical features and certain imaging findings. However, certain finer details like the presence of intramural hypoattenuating nodules and the type of mucosal enhancement may help to differentiate these two conditions. In this article, we have highlighted some of these imaging features. The importance of making an accurate diagnosis lies in the significant difference between the prognosis and the surgical management of the two disease entities.

Total pancreatic lipomatosis with malabsorption syndrome

Total fat replacement of the pancreas is rare. Focal fatty replacement is the most common degenerative lesion of pancreas. Focal fatty deposits have no major clinical significance; however, extreme fat replacement is of pathologic significance, as it is associated with marked reduction in exocrine function of pancreas, resulting in malabsorption due to pancreatic enzyme insufficiency.

Pulmonary Langerhans cell histiocytosis in children: A spectrum of radiologic findings

Pulmonary Langerhans cell histiocytosis (PLCH) is a well known entity in adults but is exceedingly rare in children. It is better described in adults than in children. We describe the current understanding of PLCH in children and a spectrum of radiological findings of PLCH in the paediatric population. On high resolution computed tomography (HRCT), PLCH may have variable appearance depending on the stage of disease, ranging from small interstitial nodular opacities to multiple thin/thick walled cysts (often bizarre in shape), eventually leading to marked parenchymal fibrosis and honeycomb pattern. CT finding of PLCH is similar in adult and paediatric populations with the exception that lung base near the costophrenic angle is spared in adults but almost always involved in children.

Neuroimaging of Langerhans cell histiocytosis: a radiological review

The neuroimaging of Langerhans cell histiocytosis (LCH), in most of the cases, is nonspecific and can vary depending on the location, especially as shown on magnetic resonance imaging (MRI). In the absence of a clinical history of LCH, isolated central nervous system (CNS) lesion presents a diagnostic challenge. LCH should be considered in the differential diagnosis of craniofacial tumors and neurodegenerative (ND) lesions of the brain. MRI is the modality of choice for investigating the CNS-LCH. Long-term follow-up with MRI is indicated in patients with ND-LCH. This retrospective study provides a comprehensive description of the spectrum of neuroimaging findings in patients with LCH, the underlying neuropathology, and follow-up study of the disease.

Postnatal outcome of congenital anomalies in low resource setting

This study aimed to determine the postnatal outcome of congenital malformations in a tertiary care hospital of India.

Pseudoaneurysm of the radial branch of the splenic artery with pancreatic pseudocyst in a child with recurrent acute pancreatitis: treatment with endovascular stent graft and cystogastrostomy

Splenic artery pseudoaneurysms (SAPs) are rare in children and usually follow abdominal trauma. Although pancreatitis is a well-known cause for SAP in adults, pancreatitis resulting in SAP has only sporadically been reported in children. Before the refinements of endovascular techniques for management of SAP, surgery used to be the mainstay of treatment, often resulting in splenectomy. Recent technical advancements, including development of smaller delivery systems and microcatheters, have made endovascular treatment feasible in children with SAP and increased chances of splenic preservation. In this article, we report a rare case of SAP associated with a pancreatic pseudocyst in a 5-year-old boy with recurrent acute pancreatitis that was managed by endovascular stent graft and cystogastrostomy.

Imaging spectrum of primary malignant renal neoplasms in children.

Wilms’ tumor (WT) is the most common abdominal tumor in children. Many pediatric renal tumors in the past were categorized as WT; however, in recent years, several specific renal tumors have been recognized as distinct pathological entities. The age and clinical presentation of the child and distinctive imaging features may help in reaching a specific diagnosis in most cases. This is important as it has implications on the pre-operative diagnostic work-up and prognosis of the child. However, it is often not possible to differentiate one from the other pediatric renal tumor on the basis of imaging alone, and the final diagnosis is often made at histological examination of the surgical specimen. This article reviews the imaging features of primary malignant renal neoplasms in children along with their clinical presentation and pathological features.

Ovarian tumors with elevated CA-125 levels and severe juvenile hypothyroidism: A need for increased awareness

A 15-yr-old girl presented with bilateral gross ovarian tumors, clinical features of long-standing unrecognized hypothyroidism and markedly elevated CA-125 levels. Ovarian resection was avoided, as the presentation was consistent with the Van Wyk and Grumbach syndrome; and the patient was treated with replacement of thyroid hormone. Regression of the ovarian tumors occurred 6 months after initiation of the treatment. The authors emphasise the need for increased awareness and screening for hypothyroidism in patients with ovarian tumors, in order to prevent inadvertent operative interventions.

Distal ulnar changes in children with thalassemia and deferiprone related arthropathy.

Regular blood transfusion and iron chelation are the standard of care for children with thalassemia. Deferiprone is an effective oral iron chelator but is known to cause significant arthropathy. Though clinical and radiographic features of deferiprone related arthropathy have been described, the long‐term effects are not known.
