“…Extending the recent observation of El Ayoubi et al 12 (28 of 70 neonates with LSV had either intraventricular hemorrhage (IVH) or periventricular leucomalacia (PVL), in this study, through the use of multivariate logistic regression, the reader will find we have confirmed that a statistically significant and unconfounded relationship exists between neonatal IVH and LSV, the latter being a lesion that we, as did Hemachandra et al 11 and Coley et al, 10 have found to be more common than reported in the older medical literature.…”

Association between Lenticulostriate Vasculopathy (LSV) and Neonatal Intraventricular Hemorrhage (IVH)

OBJECTIVES:To determine whether there is an unconfounded association between neonatal intraventricular hemorrhage (IVH) and lenticulostriate vasculopathy (LSV (also known as thalamostriate or mineralizing vasculopathy)). STUDY DESIGN:During the conduct of the Magnesium and Neurologic Endpoints Trial (MagNET), a randomized controlled trial involving maternal, hence fetal, exposure to antenatal magnesium sulfate in the context of preterm labor, head ultrasounds were obtained for each of the surviving neonates. Because of our previous experience in the diagnosis of LSV, when ascertaining the presence of IVH, as called for by the research protocol of our study, the presence or absence of LSV was also determined. RESULTS:We found LSV to be relatively prevalent (10% (14 of 140) among surviving babies). More importantly, it was significantly associated with the occurrence of neonatal IVH, even when controlled for possible confounding (adjusted OR 9.8, 95% confidence interval 1.3 to 73.1; p ¼ 0.03). CONCLUSION:Given the known relationships between IVH and neonatal morbidity and mortality, the finding of a statistically significant association between neonatal IVH and LSV may suggest more substantial implications for the latter than previously believed.

“…Linear or punctuate BGTH, although often associated with lenticulostriate vasculopathy (with basophilic deposits in arterial walls, perivascular infiltrates and mineralizing coagulative necrosis), 1,11 may occur in the absence of pathologic vascular or perivascular anomalies. 30 Whether immunologic factors (in infants of HIVinfected mothers in the absence of perinatal HIV infection) or hyperviscosity (in recipients from twin-to-twin transfusion syndrome) 24 may contribute to lenticulostriate vessel hyperechogenicity remains to be determined.…”

Objective: To determine the incidence and factors associated with diffuse basal ganglia or thalamus hyperechogenicity (BGTH) in preterm infants.Study Design: (1) Review of serial neurosonograms among neonates with gestational age (GA) <34 weeks born at Weiler Hospital during a 21-month period; (2) Color Doppler flow imaging; (3) Case-control study using GA group-matched controls; and (4) Blind reading of CT scans or MRIs in patients with BGTH.Results: Among 289 infants, 24 (8.3%) had diffuse BGTH. Color Doppler flow imaging was normal in nine patients. The incidence of diffuse BGTH was inversely related to GA (P<0.01). Logistic regression (n ¼ 96) showed that diffuse BGTH was significantly associated with requirement of high-frequency oscillation (HFO) (P ¼ 0.031), severe intraventricular hemorrhage (IVH) (P ¼ 0.004), hypotension requiring vasopressors (P ¼ 0.040), hypoglycemia (P ¼ 0.031) and male gender (P ¼ 0.014). Most patients with diffuse BGTH had normal basal ganglia and thalamus on CT/MRI, one had a hemorrhage, and one had an ischemic infarction.Conclusions: In our series, diffuse BGTH occurred in 8.3%, and was associated with factors similar to those previously reported. In contrast, several series have reported almost exclusively linear or punctuate hyperechoic foci, corresponding to hyperechogenicity of the lenticulostriate vessels. Our data provide further evidence to suggest that diffuse BGTH and hyperechogenicity of the lenticulostriate vessels are two different entities. Additional studies are required to determine the longterm significance of diffuse BGTH.

“…Thalamostriate vasculopathy on transcranial sonography has been reported in TORCH infections, particularly cytomegalovirus infection, trisomy 13, translocation chromosome 11 and various other metabolic and dysmorphic syndromes. 6 Intracranial subarachnoid cysts are usually supratentorial, but primarily in the temporal fossa and not parafalcine as in this patient. 7 Although microphthalmia is common in type 2 lissencephaly syndromes, it is not a frequent finding in Miller-Dieker syndrome.…”

Case presentation A 1910 g infant was born at 41-weeks gestation to a 19-year-old gravida 1 mother after a pregnancy complicated by hydramnios and poor fetal movement. The child was delivered by a cesarean section because of fetal decelerations with labor. Severe intrauterine growth retardation was present with the infant's weight, length and head circumference all less than the tenth percentile for gestational age. The patient's head demonstrated a wasted appearance with bitemporal shallowness. The ears were low set. Retromicrognathia, and microphthalmia, more marked on the left, were also present. The child had a cranial sonogram (Figure 1) and cranial magnetic resonance imaging (Figure 2). Denouement and discussionThe cranial sonogram demonstrated an abnormally smooth brain with no gyration or sulcation with a wide, shallow sylvian fissure creating a figure-of-8 appearance. The absence of all gyri is
