Pulmonary microlithiasis – A case report
نویسندگان
چکیده
Pulmonary alveolar microlithiasis is a rare diffuse lung disease characterized by widespread sand-like intra-alveolar calcifications (calcospherites composed of calcium and phosphorus). Around 800 cases have been reported in the literature to date. We report here a case of a 35 years old female with prolonged h/o of exertional dyspnoea and mild cough. Clinical examination was mostly normal. Her Chest X-Ray revealed bilateral multiple nodular opacities (sand storm appearance). CT Scan chest showed diffuse micronodular calcifications with septal thickening, compatible with alveolar microlithiasis. Pulmonary function tests showed moderately restrictive lung disease. Bronchoscopic alveolar lavage revealed calcospherites in the alveloli and bronchi confirming the diagnosis of pulmonary alveolar microlithiasis.

Pulmonary alveolar microlithiasis is an uncommon infiltrative pulmonary disease characterized by deposition of microliths in the alveoli. We present the case of a young adult with complaints of shortness of breath on exertion.

متن کاملA Case Report of Pulmonary Alveolar Microlithiasis
Pulmonary alveolar microlithiasis is a rare autosomal recessive disease characterized by the formation of calcium phosphate deposition in the alveoli. Although the disease most often occurs in children, most patients with the disease are diagnosed in adulthood due to the slow progression of the disease inside the lungs. In childhood, it often causes no symptoms, and changes in the lung parenchy...

Dual-energy X-ray absorptiometry (DEXA) scan has been widely used as standard method of assessing bone density. Artefacts and incidental findings are frequently encountered on the DEXA scan images, some of which may affect bone mineral density values and the others are only of incidental findings. In this case report, we present a 44-year-old male diagnosed with pulmonary microlithiasis that wa...

Background : Pulmonary alveolar microlithiasis is a rare condition characterized by a diffuse bilateral filling of the majority of alveoli by calcific concretions called calcospherits. The etiology and pathogenesis are obscure. Osteopetrosis is a heterogenous group of heritable conditions with defect in bone resorption by osteoclasts. Materials & Methods: We report a case of pulmonary alveola...

Pulmonary alveolar microlithiasis is characterized by the presence of calcospherites in alveolar spaces. Sporadic cases are more common, but the disease also presents in an inherited familial form. The greatest number of reported cases is from Europe and especially Turkey. We present a 43-year-old female with complaints of dyspnea for many years. She had a suspicious familial ...
