Pulmonary Alveolar microlithiasis, Case Report

Abstract

Background: Microlithiasis is a rare pulmonary disease, characterized by accumulation of calcium phosphates inside the pulmonary alveoli, originating nodular bodies known as microliths, this being its main characteristic. Highlighting the scarce Clinical Radiological relationship, given its poor documentation and relatively little study, it is dificult to diagnose and is often confused with other pathological entities. Clinical case: Female aged 38, controlled hypertension with atenolol 100 mg orally day, exposure to wood smoke, with 6 months of intermittent cough, dryness, dyspnea and nocturnal wheezing, a tomography was performed in the mediastial window is appreciated normal-sized heart with some adenocarcinomas of a few millimeters for non-suspect orthysts and peri-trachea, and in the pulmonary window there is bilateral diffuse homogenous alveolar illing, with nodular thickening of the lobular and septal centers with ine calciications of the pleura. The transbronchial biopsy reports alveolar spaces with presence of lamellar concentrations in intra-alveolar basophilic onion skin compatible with alveolar microlithiasis. Discussion: Identifying these particularities would allow us to perform an early approach to avoid initial complications of this disease, although there is no known curative treatment.
