Congenital infections (often referred to as TORCH infections) can present with distinct clinical syndromes in the neonatal period. Match each characteristic clinical presentation described below to its most likely causative pathogen.

  • Congenital Cytomegalovirus (CMV)A newborn presents with microcephaly, a petechial rash, and periventricular calcifications on head ultrasound.
  • Congenital ToxoplasmosisA newborn presents with macrocephaly due to hydrocephalus, chorioretinitis, and diffuse parenchymal intracranial calcifications.
  • Congenital Rubella SyndromeA newborn presents with a continuous machine-like murmur, absent red reflexes bilaterally (cataracts), and fails the newborn hearing screen.
  • Congenital SyphilisA newborn presents with copious, blood-tinged rhinorrhea, a desquamating maculopapular rash on the palms and soles, and abnormal long bone radiographs.

Cevap

The accurate pairings link Cytomegalovirus to periventricular calcifications and microcephaly; Toxoplasmosis to diffuse calcifications and hydrocephalus; Rubella to cataracts, deafness, and patent ductus arteriosus; and Syphilis to snuffles and a palmar/plantar rash.
Each classic congenital infection produces a distinct, recognizable pattern of neonatal organ system involvement that dictates the accurate match.

Adım Adım Çözüm

1
Evaluate the clinical vignette describing hydrocephalus and diffuse calcifications.
Match this presentation to Congenital Toxoplasmosis.
These findings represent the classic triad of toxoplasmosis, which often involves the brain parenchyma directly.
2
Evaluate the clinical vignette describing periventricular calcifications and microcephaly.
Match this presentation to Congenital Cytomegalovirus (CMV).
CMV preferentially affects the germinal matrix around the ventricles, causing periventricular calcifications and inhibited brain growth (microcephaly).
3
Evaluate the clinical vignette featuring cataracts, hearing loss, and a continuous machine-like murmur (PDA).
Match this presentation to Congenital Rubella Syndrome.
This is the classic rubella triad, distinguishing it as the primary congenital infection associated with severe cardiac defects.
4
Evaluate the clinical vignette featuring snuffles, a desquamating rash on the palms and soles, and bone abnormalities.
Match this presentation to Congenital Syphilis.
Syphilitic rhinitis and palmar/plantar rashes are pathognomonic for early congenital syphilis.
