Posterior fossa hemorrhage is rare in term baby and difficult to assess. The clinical signs are nonspecific and usually delay the diagnosis. We present a 5-day-old male neonate of posterior fossa hemorrhage with the initial presentations of fever and seizure and early deduced by cranial ultrasonography findings as hyperechoic, asymmetric, ill-defined density and complicated with hydrocephalus. Magnetic resonance imaging of the head verified the diagnosis. Hemophilia A was confirmed thereafter by serology.

  Introduction Top

Intracranial hemorrhage (ICH) of the posterior fossa is rare in term neonates. The clinical symptoms of posterior fossa hemorrhage are nonspecific and often similar to meningitis, sepsis, and extracranial bleeds. The typical signs include pales, vomiting, hypotonia, tense anterior fontanelle, increased of head circumference, seizure, and respiratory distress.[1],[2] The dorsal respiratory group located in the medulla oblongata is the most important respiratory center and can result in dramatic presentation to death when being involved. It is unknown about the accurate incidence of ICH of the posterior fossa because asymptomatic posterior fossa hemorrhage was underestimated and rarely diagnosed in term neonate.[1],[3]

The risk factors for ICH in term neonate include delivery methods, bleeding disorder, maternal hypertension, perinatal asphyxia, and low Apgar score.[4] Hemophilia resulting in ICH of term neonate is uncommon. The incidence was reported from 3.4% to 4.0% of the newborn with hemophilia.[5]

We reported a case of term neonate of hemophilia A with posterior fossa hemorrhage detected by cranial ultrasonography (USG).

  Case Report Top

The male neonate was born at 40 + 1 weeks' gestational age to a 30-year-old mother, gravida 1, para 0 with a birth weight of 3030 g through cesarean section. The pregnancy had been complicated by maternal right Bell's palsy during gestation 30–35 weeks, and the delivery course was prolonged for 24 h, yet the Apgar scores were 9 at 1 min and 10 at 5 min, respectively. The neonate received prophylactic intramuscular Vitamin K after birth. The patient was well-being initially, but on the 5th postpartal day, he was noted to have fever and convulsion with limbs extension, accompanied with desaturation, and decreased activity. Neonatal seizure was suspected, and after loading dose of luminal at the local clinic, he was transferred to our hospital.

His maternal uncle had a history of unknown congenital disease with mental retardation; otherwise, the family history was unremarkable.

On physical examination, he had body temperature 38.5°C, pulse 173 beats/min, respiratory rate 50 breaths/min, blood pressure 96/66 mmHg, oxygen saturation 98%–99% on room air, and his body weight 2800 g. The anterior fontanelle was flat, and his activity decreased with hypotonia. There was polydactyly of the right hand. The remainder of the physical examination was unremarkable.

The initial laboratory tests showed hemoglobin 12.5 g/dL and platelet count 322 K/uL. The spinal tapping for ruled out central nerve infection showed bloody cerebral spinal fluid. The cranial USG was arranged on admission day 1 after the cerebrospinal fluid (CSF) study. The coronal view along the plane of the choroid plexus and the midline sagittal view through the anterior fontanel [Figure 1] revealed obstructive hydrocephalus with enlarged bilateral lateral and 3rd ventricles and ill-defined hyperechoic density over the cerebellum with upward compression of the 3rd ventricle and the 4th ventricle hardly to identified. The resistive index (RI) was 0.63 (normal range: 0.6–0.9), which is through the midline sagittal view and spectral waveforms of the anterior cerebral artery. Magnetic resonance imaging (MRI) of the head [Figure 2] and [Figure 3] was soon arranged and revealed a subdural hematoma in the region of the left cerebellar hemisphere causing compression and displacement of the 4th ventricle and resulted in obstructive hydrocephalus with dilatation of the lateral and 3rd ventricles.

Midline sagittal view of sonogram (b) showed enlarged 3rd ventricle and ill-defined hyperechoic density over the cerebellum (arrow) with upward compression of the 3rd ventricle and the 4th ventricle hard to identified

The patient was intubated with ventilator support due to frequent apnea and cyanosis. Bleeding diathesis evaluation showed his prothrombin time was 10.9 s (reference range: 8.0–12 s), and an activated partial thromboplastin time was >120 s (reference range: 23.9–35.5 s). Factor VIII (FVIII) activity was <6.6% (reference range: 60%–150%). Hemophilia A was diagnosed.

Owing to personal reasons and the economic conditions of family, the parents refused surgical treatment and recombinant FVIII concentrate therapy. The patient was expired at 15-day-old unfortunately.

  Discussion Top

ICH in the neonate with hemophilia is rare and focus on posterior fossa hemorrhage in this group had not been specifically discussed in previous literature.[2],[6],[7] A case report presented a hemophilia term baby born through vacuum-assisted vaginal delivery without positive family history. His posterior fossa hemorrhage improved after surgical and intravenous recombinant FVIII replacement therapy.[8]

For the newborns with hemophilia, the safest mode of delivery still exists controversy. Kulkarni and Lusher reported that ICH in a newborn with hemophilia delivered by the cesarean section was 13% (6/47) in a review article.[6] The failure of vaginal delivery was concluded by Benedetti, as a risk factor to cause ICH and unrelated to subsequent delivery method.[9] A retrospective study to screen 20 newborns with hemophilia in the 1st week of life came out three with ICH, and all of the 3 patients had extracranial signs of bleeding/trauma through the method of instrument-assisted delivery.[7]

The family history, abnormal bleeding issues, and symptoms of extracranial hemorrhage (ECH) may give hint to hemophilia, but there are various reasons for delay diagnosis. Lack of family history in one-third hemophilia patient and the mother's unawareness as a carrier could make diagnosis a challenge. Anemia, lethargy, hypotension, and shock were common clinical presentation of both ICH and ECH, but seizure and bulging fontanel were more suggestive of ICH.[6]

The cranial USG is usually the initial image examination to screen the neonate for probable intracranial lesions. The USG had the advantages of easily available, quick, no radiation, and inexpensive and can be done at bedside. It is a useful technique in the neonatal care units. The cranial USG may visualize the posterior part hemorrhage through different planes,[10] and it is as well as computed tomography for imaging intraventricular hemorrhage or periventricular leukomalacia in preterm neonate.[11] It was not so distinct to detect posterior fossa subdural hemorrhage by USG through anterior fontanel, but there are benefits of the cranial USG through the posterolateral fontanelle.[1],[12],[13]

In our case, there were neither extracranial evidences of bleeding/trauma nor family history of hemophilia. The delivery course was smooth through cesarean section. Fever and convulsions as the initial symptoms easily confused with other conditions and lack of awareness that the neonate has congenital hemophilia. With the suspicion of intracranial lesions, it is a dilemma to send the patient for MRI examination while unstable vital signs. Cranial USG examination provided a useful and early detection of underlying intracranial lesions with or without neurological symptoms, such as ventricle dilatation, hemorrhage, ischemic change, and structure anomaly.[14],[15] The RI can be used as a tool for monitoring the intracranial pressure but may not reflect immediately. We also considered that the relative invasive CSF study could be postponed or even canceled after the cranial USG in cases with neurologic symptoms. Even though, the diagnosis of hemophilia A in this case is still challenging.
