A Case of Pulmonary Alveolar Microlithiasis

Abstract

INTRODUCTION: Pulmonary alveolar microlithiasis (PAM) is a rare chronic lung disease characterized by deposition of calcium phosphate microliths in the alveoli. CASE PRESENTATION: A 44 year old gentleman presented for right sided flank pain for 6 days. His past medical history included asthma and infertility. His vitals were stable. Physical exam was significant for mild tenderness in the right lower quadrant. CT of the abdomen showed multiple renal stones bilaterally and a 7 mm stone in the lower one third of right ureter. On day 2, he developed dyspnea. Physical exam revealed diffuse bilateral wheezing and coarse crackles. Chest X-ray showed bilateral diffuse micro-nodular opacities. CT of the chest showed bilateral diffuse calcified micronodules, interlobular septal thickening and pleural calcification. Biopsy of the lung showed concentrically arranged laminated calcified bodies and PAS-positive psammoma bodies-like microliths consistent with PAM. Considering his infertility and the diagnosis of PAM, an ultrasound of the scrotum was done, which revealed multiple calcified microliths in both the testes and epididymis.

Synthesis and Characterization of a NLO crystal - bis (thiourea) zinc sulphate doped with L-malic acid

“…The high intensity laser with the wavelength of 1064 nm was allowed to strike the sample using powder technique of Kurtz and Perry [26][27][28][29][30][31][32]. The SHG efficiency of LMBTZS is found to be 1.23 times that of KDP, confirmed by the emission of green radiation (532 nm) emitted by the sample.…”
