IntroductionCases with early diagnosis of neonatal tuberous sclerosis syndrome (TSC) are relatively seldom seen, and misdiagnosis of intracranial hemorrhage is even more rare. We retrospectively analyzed the clinical data of a case of neonatal tuberous sclerosis with atypical early symptoms and misdiagnosed as more common intracranial hemorrhage of the newborn.Patient ConcernsThe child was female and had no obvious cause of convulsion 12 days after birth. The local hospital was initially diagnosed as "neonatal intracranial hemorrhage, congenital heart disease," and still had convulsions after 5 days of treatment, so it was transferred to neonatal intensive care unit of our hospital.DiagnosisAfter admission, cardiac color ultrasound, magnetic resonance imaging, and electroencephalogram were performed, and TSC was diagnosed in combination with clinical symptoms. However, no known pathogenic mutations such as TSC1 and TSC2 were detected by peripheral blood whole exon sequencing.InterventionAfter a clear diagnosis, sirolimus, and vigabatrin were given. But there were still convulsions. Topiramate, valproic acid, and oxcarbazepine were successively added to the outpatient department for antiepileptic treatment, and vigabatrin gradually decreased.OutcomeUp to now, although the seizures have decreased, they have not been completely controlled.ConclusionsThe TSC of neonatal tuberous sclerosis is different from that of older children. It is usually characterized by respiratory distress and arrhythmia, and may be accompanied by convulsions, but the activity between attacks is normal. However, neonatal intracranial hemorrhage can be caused by premature delivery, birth injury, hypoxia, etc. Its characteristics are acute onset, severe illness, and rapid progression. Consequently, the diagnosis of these 2 diseases should not only be based on medical imaging, but also be combined with their clinical characteristics. When the imaging features are inconsistent with the clinical diagnosis, a comprehensive evaluation should be made again. The timing and pattern of onset of neonatal convulsions can help in differential diagnosis. If there is cardiac rhabdomyoma, subependymal or cortical nodule, skin low melanoma, etc, the possibility of neonatal TSC should be considered, and the diagnosis should be made according to its diagnostic criteria to avoid or reduce misdiagnosis.Copyright © 2023 the Author(s).
