APPEARANCE
Dense metaphyseal bands, less commonly known as dense metaphyseal lines, transverse bands, or lead lines, indicate radiopaque bone (thicker than the adjacent diaphyseal cortex) at the metaphysis of growing bone, particularly at the wrists and knees ( Figs 1 , 2 ). Plain abdominal radiograph in a 3-year-old patient shows multiple metallic particles due to ingested flakes of lead paint. [17]. 2002 May-Jun. Omare M, Kibet J, Cherutoi J, Kengara F.

Although in both children the MRI scans were normal, the lead-exposed boy had significant alterations in brain metabolites, with a reduced ratio of N -acetylaspartate to creatine in both gray matter and white matter. Dr Ben Still. This process is thought to be the basis for the plasticity of the developing brain or its capacity to adapt in behavior and circuitry in response to stimulation from the external environment.

The pellet was localized by means of 2-dimensional echocardiography of the left ventricular apical wall. 1996;34(1):107-8. XRF-measured bone lead (Pb) as a biomarker for Pb exposure and toxicity among children diagnosed with Pb poisoning. [16] A portable x-ray fluorescence (XRF) device has been developed to overcome these disadvantages, but introduced a measurement dependency on soft tissue thickness. the dense metaphyseal bands and generalized osteopenia persisted, and there was clear progression of the calcification of the interosseous membrane of the forearm (Fig. Radiology of syndromes, metabolic disorders, and skeletal dysplasias. {"url":"/signup-modal-props.json?lang=us"}, Datir A, Carroll D, Bell D, et al.

Usama Munir, MBBS, FRCS Orthopedic Surgeon, Department of Surgery, Whiston Hospital, UKDisclosure: Nothing to disclose. [7], Reyes et al described the CT findings of cerebral and cerebellar calcification in 3 adults with known exposure to lead of 30 years or longer, and on imaging, they found that the patterns of calcification varied and were punctiform, curvilinear, specklike, or diffuse. These included striking rickets-like changes and marked osteopenia. J Clin Endocrinol Metab 99:891897, Article Common causes of dense transverse metaphyseal lines can be remembered using the mnemonics: DENSE LINES PRINCES Mnemonics DENSE LINES D: D-vitamin intoxication E: elemental arsenic and heavy metals ( lead, bismuth, phosphorus) N: normal variation S: systemic illness E: estrogen to mother during pregnancy L: leukemia, lymphoma I infection ( TORCH) The decrease in diastolic cardiac function was more significant in the lead-intoxication group than in the nonexposed group. His cousin, who was not exposed to lead, had normal neuropsychological function. 8 (2): 55-64. If you log out, you will be required to enter your username and password the next time you visit. At the time the article was last revised Daniel J Bell had May become dense bands after treatment Most often seen in distal femur, proximal tibia (around knee), proximal humerus, distal radius, ulna Imaging Findings Lucent transverse band in the metaphysis of rapidly growing bones Generally appear of uniform thickness across metaphysis Differential Diagnosis Lymphoma Aids to Radiological Differential Diagnosis. Read and print from thousands of top scholarly journals. [QxMD MEDLINE Link]. Lead is a bluish-white metal of bright luster. Common sources of exposure to this ubiquitous metal may be broadly classified as occupational (or recreational), environmental, or perinatal (primarily trans-placental). Mennel EA, John SD.

Normal metaphyseal endochondral bone growth (in the zone of provisional calcification) requires the maintenance of a delicate balance between osteoblastic bone deposition and osteoclastic bone remodeling (. Biomed Environ Sci. Defective bone absorption can "wax and wane," leading to alternating dense and lucent metaphyseal bands and a bone-in-bone appearance.

Also have triad of hypertrophic callus formation, dense metaphyseal bands, and ossification of the interosseus membranes of the forearm. Gunshot wounds: 2. Meyer PA, Brown MJ, Falk H. Global approach to reducing lead exposure and poisoning. Infantile scurvy, historically also known as Barlow disease, is named after Sir Thomas Barlow (1845-1945), Professor of Medicine at University College London 1895-1907 5. 1986 Feb. 146(2):245-7. [QxMD MEDLINE Link]. Clin Med (Lond). [22]. Because lead and calcium are used interchangeably by bone, lead deposition occurs in high concentrations in growing bones; the greatest concentration occurs in the metaphyses, particularly those in the distal femora, ends of the tibiae, and distal radii, because these are the parts of the skeleton that grow most rapidly. 2. Unable to process the form. Plain abdominal radiographs may also guide therapy (eg, by allowing the prevention of further absorption through gastrointestinal decontamination). This may sometimes be pronounced and may lead to a false-positive diagnosis of lead intoxication. bleeding gums, petechiae), and impaired wound healing. Imaging: dense metaphyseal bands, suture separation due to lead encephalopathy (brain edema), dense ingested lead containing objects in GI tract Clinical: abdominal distension + pica Radiology Cases of Lead Poisoning Cellular and Molecular Toxicity of Lead in Bone. Musculoskeletal. Causes of lead poisoning include pica, industrial exposure, drinking moonshine liquor, gunshot wounds, retained lead pellets or particles, and a variety of folk remedies and cosmetics. Common causes of dense transverse metaphyseal linescan be remembered using the mnemonics: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. With chronic exposure to lead, patchy calcifications may be seen on MRI scans (though these are better seen on CT scans). However, cerebral edema and microhemorrhages may be seen in patients presenting with encephalopathy. Their results imply that MRS may depict metabolic abnormalities in individuals with lead poisoning. [QxMD MEDLINE Link]. 17(4):419-23. Fortschr Rontgenstr.

Scurvy is a condition caused by a dietary lack of vitamin C (ascorbic acid), hence is also called hypovitaminosis C, and is characterized by an increased bleeding tendency and impaired collagen synthesis resulting in osteoporosis and impaired wound healing. [27]. Disrupted brain plasticity is not confined to cases of lead intoxication; other clinical disorders, such as metabolic and epileptic encephalopathies, as well as psychosocial deprivation, may be associated with disrupted brain plasticity. The causes of generalized increased bone density in pediatric patients can be divided according to a broad category of causes:. Previous reports describe wide, dense metaphyseal bands and metaphyseal modeling changes in patients treated continuously and thin metaphyseal bands, increased bone density, increased growth, and decreased number of fractures in patients treated intermittently [2, 3, 5]. [26]. Hollerman JJ, Fackler ML, Coldwell DM, Ben-Menachem Y. AD: IFITM5/BRIL: VI: Moderate to severe skeletal deformity. Acta Paediatr.
