Gaucher's disease. Plain radiography, US, CT and MR diagnosis of lungs, bone and liver lesions

Gaucher disease in the liver on hepatocyte specific contrast agent enhanced MR imaging

Gaucher disease is a hereditary lipid storage disorder that affects the enzyme beta glucocerebrosidase, causing accumulation of glucocerebroside in macrophages of the reticuloendothelial system. Accumulation can occur in the liver and spleen, manifesting as hepatosplenomegaly, as well as within the bone marrow. Hepatic involvement is usually diffuse but can occasionally manifest as focal liver lesions. We present a case of a 2-year-old boy with Gaucher disease and an infiltrating liver lesion detected on imaging, which was pathologically shown to be focal changes related to the disease. Imaging characteristics of this lesion using hepatocyte specific contrast agent enhanced MRI, which have not been previously discussed in the literature, are described.

MRI of congenital and developmental abnormalities of the knee

The knee joint is the one of the most common locations for congenital and developmental musculoskeletal abnormalities. Initial imaging of the knee joint should always begin with conventional radiographs. However, evaluation of the bone marrow, cartilaginous, ligamentous, and other soft-tissue components of the knee joint are better characterized with magnetic resonance imaging (MRI). We present the MRI findings of prevalent congenital and developmental abnormalities in the paediatric knee with particular emphasis on the components of the growing skeleton.

An unusual form of Gaucher’s disease: pulmonary and cardiovascular involvement and cholelitiasis

Gaucher’s disease is an inherited storage disease caused by a deficiency of the enzyme glucocerebrosidase. Although the hepatic manifestations are seen frequently, pulmonary and cardiovascular involvements are known to be very rare in Gaucher’s disease. This report presents these rare findings made by conventional radiography, computerized tomography (CT), and High-resolution CT (HRCT) of a 16-year-old female patient with fatal Gaucher’s disease.

Gaucher disease in children: radiology of non-central nervous system manifestations

The radiological findings in paediatric Gaucher disease (GD) are reviewed and future challenges for radiology are discussed. This overview is based on a literature review and our experience of children with GD in one of two national institutions for paediatric GD in the UK. GD is known to progress more rapidly in childhood. Current imaging is mainly suitable for ascertaining the complications of GD. The UK recommendations for routine radiological surveillance are discussed. With enzyme replacement therapy (ERT), which dramatically modifies the course of the disorder, the challenge for radiology in the future is likely to be assessing treatment efficacy rather than the detection of disease complications. Disease manifestations are likely to change in those on ERT and the most notable recent alteration in the disease profile in childhood is the virtual disappearance of the acute bone crisis in this population.

Manifestações esqueléticas da doença de gaucher

A doença de Gaucher é manifestação genética causada pela deficiência da enzima glicocerebrosidase, resultando no acúmulo secundário de glicocerebrosídeos nos órgãos do sistema reticuloendotelial. Apresenta-se sob três formas clínicas distintas, podendo ser rapidamente fatal ou crônica com poucos sintomas. O presente trabalho tem o objetivo de analisar os achados da radiografia simples do esqueleto em 32 pacientes comprovadamente portadores da doença, de ambos os sexos e em diferentes faixas etárias. Foram observadas as seguintes alterações: osteopenia difusa em todos os casos, deformidade em "frasco de Erlenmeyer" em 93,7%, alterações articulares em 40,6%, necrose da cabeça do fêmur e lesões líticas em 28,1%, respectivamente, fratura patológica em 9,3% e necrose da cabeça do úmero em 6,2% dos casos. Estes resultados encontram-se de acordo com as descrições da literatura, demonstrando a importância da radiologia convencional como método complementar no diagnóstico desta enfermidade.

High-resolution CT pulmonary findings in adults with Gaucher's disease

The purpose of this study was to illustrate high-resolution computed tomography (HRCT) findings in symptomatic adult Gaucher's disease patients. Five adult patients with Gaucher's disease experienced dyspnea. These patient were first evaluated by chest X-ray (CXR) followed by HRCT. The chest X-ray on one patient demonstrated a calcified granuloma. Two patients had interstitial disease only seen on HRCT, and two patients had a combination of interstitial and alveolar disease giving a mosaic pattern better illustrated on HRCT. HRCT can be used following CXR to evaluate lung pathology in symptomatic adult Gaucher's disease patients.

Pulmonary involvement of Gaucher's disease in children: a common presentation in Saudi Arabia

All three types of Gaucher's disease may show pulmonary involvement but reports on children with pulmonary Gaucher's are rare. We present nine children with Gaucher's disease, seven of whom had lung involvement, who were followed regularly for between 1 and 7 years. Four of them received ceredase and two showed improvement of their lung pathology. Enzyme therapy with ceredase could be an effective alternative to bone marrow transplant in treating Gaucher's disease with lung involvement.

Radiographic findings in type 3b Gaucher disease

The purpose of this paper is to describe the radiographic findings in type 3 b Gaucher disease, a chronic neuronopathic form of the illness with severe systemic manifestations. Between 1980 and 1985 17 consecutive patients were evaluated with radiography of the chest, long bones and spine, CT of the head and chest, abdominal sonography, and MRI of the head, abdomen and spine. Clinical manifestations were severe, and led to death from hepatic, pulmonary or cardiac failure in nine patients. Type 3 b Gaucher disease shares the same spectrum of radiographic findings observed in type 1 disease, but the systemic manifestations are more severe. Pulmonary infiltrates, thoracic lymph node enlargement, vertebral compression fractures and osteonecrosis of the long bones occur much more frequently in patients with type 3 b disease.

Pulmonary Gaucher's disease: high-resolution computed tomographic features

CT findings in pulmonary Gaucher's disease have not been previously reported. Chest radiograph of a patient with pulmonary involvement in type I Gaucher's disease proven by biopsy showed linear and reticulo-nodular opacities. High-resolution CT demonstrated thickening of the interlobular septa and between four and six small nodules within secondary lobules, probably each corresponding to an acinus.
