[Classification and Clinical Features of Osteogenesis Several mental retardation syndromes and cognitive disorders have been recognized as being secondary to genetic disruption of intracellular signaling cascades. These metaphyseal bands, or lead lines, usually do not occur until blood lead levels (BLLs) reach 70-80 mcg/dL; they are not an early manifestation of lead intoxication. At the time the case was submitted for publication Imran Ahmad Khan had no recorded disclosures. The presence of lead foreign bodies in the gastrointestinal tract may highlight the diagnosis and prompt immediate intervention. A workup was notable for nephrocalcinosis on imaging; dense, metaphyseal bands on radiography of the hands; and calcium deposition in the cornea and skin.
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 ). In select cases, abdominal radiographs may demonstrate lead-containing paint chips (resulting from pica) or other lead-containing objects. Vitamin C is essential for collagen synthesis, acting as a coenzyme to producing cross-linking of collagen fibers. At the time the article was created Owen Kang had no recorded disclosures. Osteosclerotic metaphyseal dysplasia: a skeletal dysplasia that may mimic lead poisoning in a child with hypotonia and seizures. 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. {"url":"/signup-modal-props.json?lang=us"}, Niknejad M, Bell D, Deng F, et al.

Pediatr Clin North Am. Ralph Weissleder, Jack Wittenberg, Mukesh G. Harisinghani. Scand J Work Environ Health. Such a childhood environment fosters exposure to biologically absorbable lead through the ingestion of dust contaminated with lead paint and water contaminated from lead pipe. If the lead exposure is prolonged, there may be lack of bone modeling. CLINICAL VIGNETTE JBMR - American Society for Bone and Mineral Research [29, 30, 31] Plain radiographs, CT, angiography, and sometimes MRI may all be used to localize the missile, to determine the path it followed in the body, to assess missile and bone fragmentation, and to identify missile emboli. Mennel and John reported a case of a 23-month-old boy with osteosclerotic metaphyseal dysplasia (OMD). [QxMD MEDLINE Link]. [Full Text]. [QxMD MEDLINE Link]. Piomelli S. Childhood lead poisoning. Opaque metaphyseal bands are also seen after poisoning with other heavy metals; with hypervitaminosis D; and during the healing stages of leukemia, rickets, and scurvy. They appear on radiographs as bone that is more radiopaque that the adjacent diaphyseal cortex. They revealed dense metaphyseal bands at both distal femoral physes with adjacent proximal horizontal bands of radiolucency suggestive of zone of provisional calcification with Trummerfeld zones. In addition, the distal ends of the long bones may disappear and appear clubbed. [26]. Radiology. The mechanisms of contamination include ingestion, inhalation, prenatal exposure, and dermal exposure, but the most common are ingestion and inhalation. [QxMD MEDLINE Link]. The authors examined 2 male cousins who were living in the same household. At the time the article was created Abhi Datir had no recorded disclosures. In children, the density and width of the lead bands are well correlated with the concentration of lead ingestion or inhalation, as well as with the duration of lead exposure.

Functional MRI now offers the means to noninvasively study this plastic reorganization of the brain in children and adults. [16] A portable x-ray fluorescence (XRF) device has been developed to overcome these disadvantages, but introduced a measurement dependency on soft tissue thickness. "Dense metaphyseal bands"[Clinical Features] OR 866573[uid] - MedGen Result All 3 patients had nonspecific neurologic symptoms of dementia, loss of visual acuity, peripheral neuropathy, syncope, dizziness, nystagmus, easy fatigue, or back pain. The classic findings of lead lines on radiographs of long bones are rarely seen because most cases of lead poisoning in children are due to exposures to low or moderate amounts of lead. However, cerebral edema and microhemorrhages may be seen in patients presenting with encephalopathy. Fortschr Neurol Psychiatr. Muscle Nerve. Perelman et al reported a case in which MRI results excluded a focal mass, and early treatment of edema prevented neurosurgical exploration. J Comput Assist Tomogr. Hu et al measured bone lead levels in 34 adults with no known history of excessive lead exposure and found that bone lead levels were greater in older persons; they concluded that theKXRF technique may help distinguish low levels of lead burden, as shown in epidemiologic studies. ADVERTISEMENT: Supporters see fewer/no ads. A Dictionary of the History of Medicine. Plain radiography of the knee is an inexpensive and widely available investigation that may be rapidly performed. Lead resists corrosion; in fact, lead pipes bearing the insignia of Roman emperors that were used as drains from the baths are still in service. 1985 Aug. 48(8):814-8. The skull and vertebral bodies appeared unaffected. In infants with severe lead poisoning, the bands may be wide and may prevent normal remodeling. 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. Dense transverse metaphyseal lines (mnemonic) - Radiopaedia (2015) Interdisciplinary toxicology. Patients at risk include elderly males, alcoholics, smokers and those with malabsorptive diseases.

Some observations on bone growth, with particular respect to zones and transverse lines of increased density in the metaphysis. The other patient, the last patient of the series, was a 2.5-year-old Poznanski AK. Specht AJ, Weisskopf MG, Nie LH.

Single transverse lines predominate, but multiple bands may be seen in cases of episodic lead poisoning.
