Although no distinctive neurologic syndrome could be demonstrated, the incidence of hypertension and hyperuricemia was increased in the affected patients, and serum creatinine levels were increased. Normal bone is laid down on the epiphyseal side of the lead line; with recovery, the lead line becomes broader and less dense and may eventually disappear. [QxMD MEDLINE Link].

Also, see eMedicineHealth's patient education article Poisoning. may show bands of increased density at the metaphyses can affect any metaphysis, but the involvement of the proximal fibula and distal ulnar metaphyses is highly suggestive may show bone-in-bone appearance abdominal radiographs utile for identification of exposure source and anatomic location if an ingestion is suspected 7 The images showed thick sclerotic bands in the metaphyses around the knee joints, findings that were attributable to her denosumab chemotherapy. W B Saunders Co. (1984) ISBN:0721673171. [26]. These patterns were found in the subcortical area, basal ganglia, vermis, and cerebellum. The patient in the study by Schrote et al had a 25-year history of normochromic normocytic anemia with moderate basophilic stippling, mild renal failure, hyperuricemia, and abnormal porphyrins. Selhi H & White J. These abnormalities suggest that the underlying defect in type V OI may involve a molecule common to both bone and cartilage that is involved in the regulation of growth plate development and metadiaphyseal . show answer. Mild flaring along metaphyseal corners was noted at distal femoral metaphysis suggestive of Pelkan spurs. 36(2):90-3. [19], CT plays a minor role in the diagnosis of lead poisoning. Table 1.

Dense sclerotic metaphyseal bands caused by denosumab therapy Trope et al found that that magnetic resonance spectroscopy (MRS) may have a role as a noninvasive technique for the in vivo examination of the brain of children exposed to lead.

View Mohammadtaghi Niknejad's current disclosures, see full revision history and disclosures, alternating radiolucent and radiodense metaphyseal lines. 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. Some observations on bone growth, with particular respect to zones and transverse lines of increased density in the metaphysis. Findings occur more frequently in younger patients with open epiphyses. Had a bone marrow transplant recently. Perelman et al reported a case in which MRI results excluded a focal mass, and early treatment of edema prevented neurosurgical exploration. milder pediatric cases may manifest with disturbances in behavior, growth, hearing and cognition, severe pediatric cases may progress to encephalopathy with seizures, coma, ataxia, cerebral edema, adults may similarly demonstrate mild (tired, irritable) symptoms or a severe encephalopathy, peripheral motor neuropathy may also develop, elevations (chronic) in zinc and erythrocyte protoporphyrin, may impair spermatic function and spermatogenesis, bone remodeling and growth may be affected in pediatric cases, with proposed mechanisms including 10, alterations in circulating endocrine factors such as parathyroid hormone and activated vitamin D, derangement in paracrine signaling factors such as osteocalcin, direct cellular toxicity, particularly affecting osteoclasts, growth trajectory and height may be affected, pathologically increased deposition of calcium in the zones of provisional calcification responsible for the dense metaphyseal bands on radiographs referred to as "lead lines", including aminolevulinic acid dehydratase and ferrochelatase 9, may impair production of erythropoeitin 6, erythrocyte functional and structural derangements, inhibition of erythrocyte sodium-potassium pump 8, predisposing to breakdown of the cell membrane and hemolysis, residual nucleotide clumps in cytosol appear as basophilic stippling, may show bands of increased density at the metaphyses, can affect any metaphysis, but the involvement of the proximal fibula and distal ulnar metaphyses is highly suggestive, abdominal radiographs utile for identification of exposure source and anatomic location if an ingestion is suspected 7, intra-luminal radio-opaque foreign body (or multiple punctate densities), serial radiographs may be used to monitor effectiveness of bowel decontamination, identification of source crucial to prevent ongoing toxicity 6, decontamination of ongoing sources of enteral absorption (paint chips, foreign bodies), some patients may require chelating agents to enhance elimination, also known as "British anti-Lewisite" or BAL, also known as succimer, the favored available oral chelating agent over d-penicillamine. The pellet was localized by means of 2-dimensional echocardiography of the left ventricular apical wall. BLLs were normal. Dense transverse metaphyseal lines (mnemonic) - Radiopaedia You are being redirected to [13] These lines, which are actually growth arrest lines, are not pathognomonic for lead poisoning (see the images below).

[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. Am J Roentgenol Radium Ther Nucl Med. Understanding how the brain's circuitry is sculpted during development provides an important perspective for thinking about neurodevelopmental disorders. Pediatrics. In addition, T2-weighted MRI showed high signal intensity in the periventricular white matter, basal ganglia, insula, posterior thalamus, and pons. Fortschr Neurol Psychiatr. This is the origin of the word plumber and plumbing as lead has been widely used for water pipes in the home since Roman times, and also 'plumbism', a synonym for lead poisoning 5. physiological appearances in <3 years' age group, ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Do not surround your terms in double-quotes ("") in this field. Osseous changes occurred on CT in 69% of patients, and on computed chest radiography in 53%. Eur Spine J. In 6 infants, there was evidence of multiple lead lines, indicating previous episodes of exposure to lead. A: Some of the common causes include chronic anemia, healing rickets and renal osteodystrophy. AJR Am J Roentgenol. no financial relationships to ineligible companies to disclose. Biomarkers. 21 (4):347-52. By excluding more serious causes, this finding was proved to be a normal variant. 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 [QxMD MEDLINE Link]. Radiographic features of bisphosphonate therapy in pediatric - Springer Frankel line: dense zone of provisional calcification Trmmerfeld zone: lucent metaphyseal band underlying Frankel line Pelkin spur: metaphyseal spurs that result in cupping of the metaphysis Pelkin fracture: metaphyseal corner fracture Adults osteopenia pathological fractures Ultrasonography is not routinely used in the diagnosis of lead intoxication, though transcranial sonography may be used to investigate congenital lead poisoning and lead intoxication in infant patients presenting with lead encephalopathy. [28] A slightly elevated blood lead level (BLL) of the patient was alarming because of the possibility of subsequent lead poisoning associated with retained pellets. 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.
