Spontaneous Simultaneous Bilateral Basal Ganglia Hemorrhage (SSBBGH): Systematic Review and Data Analysis on Epidemiology, Clinical Feature, Location of Bleeding, Etiology, Therapeutic Intervention and Outcome

Mirror Image of Spontaneous Intracranial Hemorrhage

In this paper, we reported the first case of mirrored spontaneous intracranial hemorrhage with almost identical hematoma morphological characteristics. This patient's first symptom was loss of consciousness, without any local neurological symptoms. This clinical presentation fits well with the atypical computed tomography (CT) image showing bilateral hematomas, and indicates that the distribution of hypertensive vascular damage may be symmetric and that the degree of the bilateral lesions may be similar.

Spontaneous Simultaneous Bilateral Basal Ganglia, Thalamic, and Central Pontine Haemorrhage: A Case Report

The basal ganglia, a complex of subcortical nuclei, form an important functional component of the brain. Spontaneous simultaneous bilateral basal ganglia haemorrhage (SSBBGH) is exceedingly uncommon and often associated with hypertension as a primary predisposing factor. We report a case of a 72-year-old female who presented to a local hospital following a dizzy spell and subsequent fall. Non-contrast CT brain revealed bilateral basal ganglia haemorrhage alongside central pontine haemorrhage. Subsequently, she was transferred to our tertiary-care specialist stroke unit where conservative management was pursued. She was discharged after brain imaging, multidisciplinary team (MDT) consultations, and follow-up plans. The MDT comprised stroke physicians, radiologists, physiotherapists, occupational therapists, and speech and language therapists. Given the limited number of documented cases of this rare occurrence (approximately 60 in the literature), we believe this report will contribute to the existing body of knowledge.

Bilateral basal ganglia hemorrhage in a 2-year-old child

Background

Basal ganglia hemorrhage (BGH) is an intracerebral subtype of hemorrhage located in the caudate nucleus, putamen, globus pallidus, or adjacent structures such as the thalamus or internal capsule. Bilateral involvement of both basal ganglia is exceedingly infrequent. Herein, we report a case of a 2-year-old female who was discovered to have spontaneous bilateral BGH with a unique hemorrhagic extension.

Case Description

A 2-year-old female child who presented with a decreased level of consciousness, seizure, and fever was discovered to have bilateral BGH during imaging evaluation that extended from the head of the caudate to involve the putamen, globus pallidus, and anterior limb of the internal capsule.

Conclusion

Bilateral BGH is extremely rare, and to the best of our knowledge, this is the first case report in pediatric age groups.

A case of spontaneous basal ganglia hemorrhage with contralateral extension utilizing the canal of Gratiolet

BACKGROUND

Intracranial hemorrhage accounts for 10-20% of stroke etiologies annually. Basal ganglia is the most common site for intracranial hemorrhage accounting for 50% of all cases. Bilateral spontaneous basal ganglia hemorrhages (BGH) are rare with few reported cases.

CASE PRESENTATION

We report an unusual case of a 69-year-old female who presented with a spontaneous bilateral basal ganglia hemorrhage secondary to a right BGH with contralateral extension through the anterior commissure (AC) utilizing the Canal of Gratiolet. Clinical course and imaging findings are discussed.

CONCLUSIONS

To our knowledge, this is the first case to specifically detail the extension of spontaneous hemorrhage across the AC via the Canal of Gratiolet, and imaging findings provide a novel depiction of AC anatomy and fiber distribution in a clinical context. These findings may explain the mechanism behind this rare clinical entity.
