CliniCian’s Corner Case 2: An 11-week-old female infant with multiple bruises A n 11-week-old female infant was brought to the emergency department by both of her parents, who were concerned about abdominal marks that resembled bruising. The parents did not have any explanation for the marks, stating they “just came up like that”. No history of falls or injuries was reported. The infant was born following an uncomplicated pregnancy and vaginal delivery, and had received vitamin K prophylaxis at birth. No bleeding after umbilical stump detachment was reported. On examination, the child measured within the normal ranges for height, weight and head circumference. Notable findings included four round bruises 1 cm to 1.5 cm in diameter (separated by 1 cm to 3 cm) on the upper left abdomen; normal frenulae; no adenopathy or joint issues; nondistended, nontender abdomen; and no hepatosplenomegaly or masses. The anus and genitalia appeared normal. Three additional bruises (right and left forearm, mid-upper back) were discovered by the examining physician and had not been reported by the parents. Investigations were initiated.

A repeat survey two weeks later revealed callus formation on the posterior 10th and 11th ribs. A computed tomography scan of the head and abdominal ultrasound were normal. The infant’s platelet levels, international normalized ratio, partial thromboplastin time, fibrinogen, factor XIII and von Willebrand factor levels were normal. A differential diagnosis of bruising in a young child should consider inflicted trauma, accidental causes and underlying medical conditions. box 1: susPeCted Child PhysiCal abuse • DSMIVCodeV61.21 • International Classification of Disease, Ninth Revision, Clinical Modification Code 995.50 (www.icd9data.com) • International Classification of Disease, Tenth Revision, Clinical Modification Code T76.12XA, T76.12XD, T76.12XS (www.icd10data.com) • Othercommontermsusedbyhealthprofessionalsinclude child maltreatment, child ill-treatment or nonaccidental injury Age is critical: the preambulatory child cannot self-bruise. A diagnosis of child physical abuse (CPA) (Box 1) is strengthened by multiple areas of bruising, absence of a causative history, atypical location of bruises (ie, abdomen, back, ears, torso and neck) and clustered/patterned bruises, which may point toward a mechanism of injury (1). Bleeding disorders may present with ‘easy’ bleeding, particularly after umbilical stump detachment or postcircumcision (2). Previous bruising could suggest either noninflicted or inflicted causation. For example, a bleeding disorder can be associated with bleeding from the mucosa of the mouth, particularly with brushing teeth, or recurrent spontaneous nosebleeds (3). A positive family history (because many bleeding disorders are heritable) would support an organic cause for the child’s bleeding (3). Normal clotting tests decrease the likelihood of a bleeding disorder. Importantly, abused children can also have bleeding disorders. Physical examination (‘top-to-toe’) is critical for the evaluation, and diagrams of bruises or photography may be helpful. Bruises cannot be reliably dated. All maltreatment types (ie, neglect, sexual abuse) need to be considered (3). Findings such as lymphadenopathy or hepatosplenomegaly are indicative of an organic cause. Hypermobility may indicate a connective tissue disease, which may thin skin and result in easy bruising (3). A full work-up is necessary for children two years of age and younger (3). Skeletal surveys are critical for evaluating the extent of CPA. Fractures, such as clavicle injury, are not uncommon with the birthing process, especially during vaginal delivery. However, by this age, healing should have occurred. Callous formation can help to determine the timing of the trauma; bone mineralization can also be assessed. Evidence of a disorder of bone fragility (ie, blue sclera or positive family history) leads to consideration of a disorder such as osteogenesis imperfecta; however, normal findings Paediatr Child Health Vol 18 No 5 May 2013 on skeletal survey makes this very unlikely. Posterior rib fractures are highly specific for CPA (4). In our case, the two-week follow-up skeletal survey revealed new fractures, supporting a CPA etiology. CPA is consistent with the clinical picture, given bruising in a nonambulatory infant; lack of explanation offered by parents; history of unusual injury; multiple bruises in atypical locations; posterior rib fractures; normal blood clotting abilities in an otherwise healthy infant; and normal bone structure. Infants and toddlers, as opposed to older children, are more likely to suffer CPA, severe CPA and recurrent CPA (5). A computed tomography scan of the head should be considered, even if the neurological examination is normal (6). It is important to add measurement of alanine aminotransferase, aspartate aminotransferase and amylase levels, and abdominal imaging to the investigation in cases involving abdominal bruising. Suspicion of maltreatment must lead to contact being made with the local child protection agency. Although there was no previous child welfare involvement, a physician visit at eight weeks of age for a bruised tongue and an emergency department visit at four weeks of age for bleeding from the mouth were opportunities for intervention. CliniCal Pearls • Bruisesinthepreambulatoryinfantshouldraisearedflagfor CPA. • Bruisingcanbethemanifestationofanorganiccause. Knowledge of common conditions associated with bruising in an infant is important. If suspicion exists for CPA, a report should be made to the local child protection agency. While delay in seeking medical attention can be a maltreatment correlate, delay among health professional can lead to more severe injuries. reFerenCes 1. Jenny C.
