Metastatic Calcinosis Cutis: Unusual Locations in End-Stage Renal Disease.

Metastatic calcinosis cutis is a rare consequence of end-stage renal disease (ESRD), which occurs due to elevated levels of serum phosphorus and abnormal phosphate and calcium metabolism, leading to the precipitation and deposition of calcium in the cutaneous and subcutaneous tissues. This paper reports the case of a 33-year-old male with ESRD and a six-year history of hemodialysis treatment who presented with multiple areas of gradually enlarging, lobulated calcified soft tissue masses observed bilaterally at the level of the acromioclavicular joint and superomedial aspect of the right thigh, extensively involving the perineal region and the right superior anterior chest wall. The unique character of this case is the rare involvement of the sternoclavicular joint and the symphysis pubis. The relevant laboratory findings included elevated levels of serum phosphorus, blood urea nitrogen, and creatinine, which were consistent with metastatic calcinosis cutis as a consequence of ESRD. The treatment of secondary calcinosis cutis primarily includes low-calcium and low-phosphorus diets, dialysates, and phosphate binders, except aluminum-containing binders, which were advised for this patient. Imaging is the mainstay for the diagnosis of calcinosis cutis, and as metastatic calcinosis cutis is an infrequent and debilitating consequence of ESRD, prompt diagnosis and appropriate treatment are paramount.

Normal sulcation and gyration in neonatal cranial sonography from 24 weeks gestational age until term: a pictorial essay.

Cranial ultrasound remains the most practical and available imaging modality for evaluating the brain of neonates. This is a pictorial essay on preterm (≥24 weeks) and term neonates who had an unremarkable cranial ultrasound in the first week of life at St. Luke's Medical Center Quezon City and St. Luke's Medical Center Global City from January 2017 to December 2021. We present two images for each landmark week of gestation in this retrospective multicentric review. The first image is in the coronal plane depicting the foramen of Monro and the third ventricle and the second image is in the sagittal plane at the level of the caudothalamic groove. The goal is to create an easy-to-use reference for the typical appearance and progression of the normal sulcation and gyration of the neonatal brain on ultrasound, depending on the weekly gestational age. Having a reference atlas matched for gestational age is a helpful tool for screening a myriad of pathologies and is expected to help clinicians and radiologists involved in the care of neonates monitor the development of the brain.
