The appearance of soft tissue calcifications in patients with chronic renal failure has been recognised as one of the serious complications of uremia. An elevated serum calcium-phosphate product has almost invariably been detected, although the exact mechanisms of precipitation are still not fully understood. Among the factors responsible for triggering the precipitation process are: hyperphosp...
Dystrophic calcifications of the aortic valve may cause symptomatic aortic stenosis and account for a significant portion of patients who undergo elective valve replacement. Calcifications appearing grossly as a cloudy fluid surrounding the aortic valve leaflets are an uncommon finding. Normally, calcified aortic valves are characterised by large, nodular masses within the aortic cusps. We repo...
OBJECTIVE To describe a case of adrenal cavernous hemangioma in a 67 year old man who presented left lumbar pain. METHODS Abdominal ultrasound, contrast enhanced ultrasound of the lesion, abdominal-pelvic CT scan, and then left adrenalectomy and pathology were performed RESULTS Imaging studies showed a large solid-cystic mass with 12 × 11 cm diameters in the left adrenal gland, well defined...
Objectives: The objective of this case report was to determine radioopacities of the cervical region on panoramic radiographs using doppler ultrasound. Methods: 3 patients with radio-opacities of the cervical region on digital panoramic radiographs were referred to doppler ultrasound for further diagnosis. Results: In 2 cases carotid artery calcifications were identified as an irregular radio-o...
For the radiologist, calcifications in an abdominal malignancy raise questions of both diagnostic and prognostic significance. Although certain cancers are well known to calcify, such as colorectal and ovarian, malignant abdominal calcifications actually arise from a wide variety of epithelial, mesenchymal, lymphoid, or germ cell neoplasms. The pathophysiology of calcification in abdominal mali...
Subcutaneous calcifications can lead to complications, including pain, inflammation, ulceration and immobilization. Studies on the pathophysiology of mineral compositions and effective treatment modalities are limited. We therefore studied 14 patients with subcutaneous calcifications. Mineral material was collected and analysed by Fourier transform infrared spectrometry. Blood analyses were run...
Nine members of a family spanning three generations showed bilateral calcifications of the basal ganglia with autosomal dominant inheritance. Two members developed chorea, dementia, and a characteristic speech disturbance (palialalia) in the third or fourth decade. A third member possibly shows the initial stage of a similar syndrome. Six members with calcifications but without neurological sig...
We are reporting an unusual case of widespread abdominal calcifications, in the peri-colic mesentery, liver and spleen. The diagnostic laparoscopy showed multiple encapsulated calcified hard rounded masses of varying size and shape, with marked adhesions in and around the bowel and mesentery. Histopathology identified them as calcified lymph nodes, but was unable to highlight the pathogenesis o...
Intermittent pelvic pain caused by ovarian cysts in adolescence may be due to torsion or partial torsion of the ovary. We present a case of 18-year old adolescent with symptomatic left ovarian torsion with calcifications demonstrated by pelvic MRI and ultrasonography prior to surgery. The pathologic investigation demonstrated dystrophic calcifications. We speculated that the pattern of the inte...
A standout amongst the most effective strategies for bosom malignancy early discovery is mammography. Another strategy for identification and arrangement of miniaturized scale calcifications is displayed. It should be possible in four phases: in the first place, pre processing stage manages clamour expulsion, and standardized the picture. Second stage, K-Means bunching (KMC) is utilized for div...
