Pulmonary findings in Gaucher's disease

Radiological aspects of Gaucher disease

Advances in imaging and the development of commercially available enzyme therapy have significantly altered the traditional radiology of Gaucher disease. The cost of treatment and need for monitoring response to therapy have magnified the importance of imaging. There are no recent comprehensive reviews of the radiology of this relatively common lysosomal storage disease. This article describes the modern imaging, techniques and radiological manifestations of Gaucher disease.

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.

Pulmonary Langerhans cell histiocytosis and other pulmonary histiocytic diseases: a review

CONTEXT

Pulmonary Langerhans cell histiocytosis is the most common and best known pulmonary histiocytic lesion; however, the realm of pulmonary histiocytic lesions also includes an assortment of uncommon diseases that may exhibit pulmonary involvement.

OBJECTIVE

To review pulmonary Langerhans cell histiocytosis and other pulmonary histiocytoses to better ensure correct diagnosis and optimal assessment of prognosis and treatment.

DATA SOURCES

Literature review and primary material from the author's institution.

CONCLUSIONS

This review discusses the most common pulmonary histiocytosis, pulmonary Langerhans cell histiocytosis, and also reviews the uncommon pulmonary histiocytic lesions, which are distinct from pulmonary Langerhans cell histiocytosis.

Pulmonary involvement in type 1 Gaucher disease: functional and exercise findings in patients with and without clinical interstitial lung disease

Pulmonary disease is a well-known complication of Type 1 Gaucher disease (GD), although its incidence is not well established and its severity varies. The purpose of this study was to determine the frequency and extent of pulmonary involvement in patients with GD. Pulmonary involvement was assessed by history, physical examination and chest radiograph in 150 consecutive patients with Type 1 GD presenting at a specialized center for genetic diseases. Five patients were noted to have clinical evidence of pulmonary involvement. Full pulmonary function tests were performed in these five patients and in an additional 13 patients randomly selected from the remaining 145. Many of the 18 patients also underwent radionuclide body imaging with 67 Gallium citrate and 111Indium-tagged leucocyte scans, as well as incremental cardiorespiratory exercise tests. Lung biopsies were available in two patients with lung disease, and a second examination of lung tissue was performed in one of these two patients post-mortem. Clinical lung disease was detected in five patients. All five had dyspnea, diffuse infiltrates, restrictive impairment and low single breath CO diffusing capacity (DLCOSB). Two of these patients underwent exercise testing and showed abnormalities consistent with lung disease (ventilatory limitation, excessive ventilation and increased dead space) as well as decreased VO2 max. and anaerobic threshold (AT). In contrast, in the other 13 patients, physical examination, chest radiographs and pulmonary function were normal (except for a low DLCOSB in one patient). Responses on exercise testing (performed in six of the 13 patients) were consistent with a circulatory impairment (decreased VO2 max. and AT). Our study found that <5% of patients with Type 1 GD have clinical interstitial lung disease. In addition, we found that some patients, without evident lung involvement, may experience limitations in physical exertion and are easily fatigued; this is attributable to impaired circulation.

[Persistence of pulmonary lesions in a 6-year-old boy with type I Gaucher's disease treated by alglucerase since the age of 20 months]

BACKGROUND

Gaucher's disease is a serious disorder which becomes curable by bone marrow transplantation. Enzyme replacement therapy has permitted improvement in quality of life and has been shown to decrease the disease's progression.

OBSERVATION

A 6-year-old boy was treated by alglucerase (Ceredase) since the age of 20 months. He presented at that time a failure to thrive, pancytopenia, hepatosplenomegaly and bone involvement. The lung X-rays revealed a diffuse reticulonodular pattern. After 4 years and 5 months, there was an improvement of growth and hepatosplenomegaly, associated with hematological parameters and bone changes normalization. However, an important interstitial syndrome without clinical signs persisted.

CONCLUSION

In our patient it is impossible to note the difference between pulmonary disease from fibrotic origin and pulmonary involvement by Gaucher's cells accumulation.

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.

Gaucher's disease: clinical features and natural history

Gaucher's disease is an inherited disorder characterized by pathological storage of glycolipid in mononuclear phagocytes: it is a multi-system disease associated with striking variation in its clinical manifestations, severity and course. Although molecular analysis of the glucocerebrosidase gene in patients with Gaucher's disease has permitted broad correlations between genotype and phenotype to be made, with few exceptions genetic variation at this locus does not allow confident prediction of clinical phenotype or prognosis. Partial deficiency of glucocerebrosidase is associated principally with parenchymal disease of the liver, spleen, bone marrow and, in severe cases, the lung, in non-neuronopathic, Type 1, Gaucher's disease: here storage material in macrophages originates from turnover of exogenous glycolipids. Severe deficiency of glucocerebrosidase caused by disabling mutations is additionally associated with neurological manifestations that in part reflect a failure to degrade endogenous neuronal glycosphingolipids, the so-called neuronopathic, Type 2 and Type 3 disease categories. Here we describe the clinical features, complications and natural history principally of Type 1 Gaucher's disease: emphasis is placed on emerging pulmonary, osseous and other manifestations of obscure pathogenesis that respond poorly to enzyme-replacement therapy.

Pulmonary involvement in adult Gaucher's disease: high resolution CT appearance

High resolution CT findings of pulmonary involvement are described in a patient with adult type Gaucher's disease. Although the reticular pattern on the chest radiograph was typical, appearance of pulmonary involvement on high resolution CT has not been demonstrated in the literature. High resolution CT demonstrated interlobular septal and intralobular interstitial thickening, irregular interfaces at the pleural surfaces and ground-glass appearance, corresponding to both the alveolar and the interstitial components of the pulmonary 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.

Fatal respiratory failure caused by pulmonary infiltration by pseudo-Gaucher cells

Pseudo-Gaucher cells are reticuloendothelial cells that are found in several diseases. We report a case of pulmonary tuberculosis in which extensive pulmonary involvement with these cells resulted in fatal respiratory failure.

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

We report our observations made by conventional radiography, ultrasound, computerized tomography (CT), and magnetic resonance imaging (MRI) on a 3 1/2-year-old girl with Gaucher's disease. The interest of the case consists in the exceptional lungs involvement, the demonstration by MRI of the bone marrow involvement and the necrosis and fibrosis of the liver, as shown by CT. This liver complication has been previously reported only once.

Gaucher disease--Norrbottnian type. I. General clinical description

We report follow-up studies of 22 cases of the Norrbottnian type of Gaucher disease ("type III"). The series was divided into 2 main groups of families depending on their birth province (Norrbotten, Västerbotten). The distribution and types of organ manifestations and complications were the same in both groups, each of which was considered to be genotypically homogeneous. The severity of the clinical symptoms and signs and the course of the disease differed markedly not only between families but also between siblings. Splenectomy accelerated deterioration, particularly with regard to skeletal and central nervous system manifestations. On a clinical basis it is concluded that the Norrbottnian type of Gaucher disease, which has now been diagnosed in about 40 cases, is probably due to a unique mutation which may have happened several hundred of years ago in northern Sweden.

Unusual cardiac, renal and pulmonary involvement in Gaucher's disease. Intersitial glucocerebroside accumulation, pulmonary hypertension and fatal bone marrow embolization

A 25 year old black woman who had manifestations of Gaucher's disease since one year of age is described. This patient had clinically significant cardiac, renal and pulmonary involvement with Gaucher's disease. Interstitial infiltration of the myocardium by Gaucher cells caused decreased left ventricular compliance and decreased cardiac output. In the kidney, Gaucher cells were present in the mesangium of the glomeruli and the interstitium of the cortex. Also, electron dense, intramembranous granular deposits were seen in glomeruli on electron microscopy. The pulmonary findings included pulmonary arterial hypertension, accentuated basilar deposition of glucocerebroside in the interstitium of alveolar septums and fatal bone marrow embolization.
