A 16-year-old female patient with systemic lupus erythematosus (SLE) presented with abdominal pain and oliguria, after one month of hospital treatment with methylprednisolone and cyclophosphamide. Computed tomography of the abdomen revealed the calcification of bilateral superior segmental ureteral wall. Computed tomography urography revealed stenosis of bilateral ureters. This calcification may be associated with lupus-induced inflammatory reaction of ureteral endomembrane. By receiving the ureteral catheters, her abdominal pain and oliguria had been completely resolved. After discharge, she underwent the surgery of cutaneous ureterostomy in the local hospital. During two years follow-up, her condition is stable without any symptom of the urinary system.

Idiopathic mesenteric phlebosclerosis, rare disease entity causing chronic mesenteric ischemia is a member of non-thrombotic, non-inflammatory stenosis or occlusion of the mesenteric veins. The histologic hallmark is marked fibrous mural thickening and sclerosis of the vessel wall. It is frequently accompanied by calcification in the vessel wall. We report the case of a 61-year-old woman with idiopathic mesenteric phlebosclerosis. To our knowledge, this is the first case reported in Korea.

Calcific myonecrosis is a rare late post-traumatic condition, in which a single muscle is replaced by a fusiform mass with central liquefaction and peripheral calcification. Compartment syndrome is suggested to be the underlying cause. The resulting mass may expand with time due to recurrent intralesional hemorrhage into the chronic calcified mass. A diagnosis may be difficult due to the long time between the original trauma and the symptoms of calcific myonecrosis. We encountered a 53-year-old male patient diagnosed with calcific myonecrosis in the lower leg. We report the case with a review of the relevant literature.

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

INTRODUCTIONPseudoxanthoma elasticum (PXE) is an inherited multisystem disorder of the elastic tissue and the objective of this case report is to correlate ultrasonographic and histological appearances of placental calcification in PXE.

CLINICAL PICTUREWe report a case of a 37-year-old white woman with PXE, whose antenatal imaging showed a markedly echogenic placenta due to extensive calcification confirmed on postpartum placental histology.

OUTCOMEThere were no maternal or fetal complications in the antenatal period. A healthy baby of appropriate maturity and weight was delivered via Caesarean section and remained well at 6 months.

CONCLUSIONThe majority of cases of PXE is caused by mutations in the ABCC6 gene. Serious complications in pregnancy can include gastrointestinal haemorrhage, congestive heart failure and cardiac arrhythmia but has not been shown to be associated with markedly increased fetal loss or adverse reproductive outcomes as reported in previous literature. Apart from the cosmetic deterioration of the abdominal skin, there were few serious complications and most have normal pregnancies. Obstetric prognosis is dependent on the vascular damage caused by the illness. There is no basis for advising women with PXE to avoid becoming pregnant, and most pregnancies in PXE are uncomplicated.

It is never an easy thing to diagnose heart vascular disease only depending on the unenhanced postmortem computed tomography (PMCT). This article reported a case of sudden natural death after the complaint of anterior chest pain in which coronary artery calcification (CAC) was clearly displayed using PMCT scan. The entire coronary artery system was almost reconstructed via multiplanar reformation (MPR) and volume-rendering reconstruction (VR), and the total calcium score of the coronary arteries was obtained with CaScoring automatic analysis software. The results showed that CAC was conspicuous; the total calcium score was 640.3, considerably higher than 400. The pulmonary ground-glass opacity (GGO) and small amount of fluid both in the subglottic trachea and main bronchi were also found. The imaging results confirmed those of autopsy. In addition, the results concluded that PMCT might serve as an invaluable adjunct to the classic autopsy procedure.

Renal angiomyolipomas are benign neoplasms composed of varying amounts of adipose tissue, smooth muscles and blood vessels. They typically contain macroscopic fat, which is seen as negative attenuation on computed tomography. Calcification and scarring is rarely seen in renal angiomyolipomas. We report the case of a 40-year-old man who was found to have a renal angiomyolipoma with a central stellate scar and focal calcification. The lesion was initially misdiagnosed as a calyceal calculus.
