The superior sagittal sinus (SSS) is a midline structure of the superficial cerebral venous system that drains the anterior cerebral hemispheres. Hypoplasia of the rostral SSS is a known variant, although associated complications are rare. A woman in her 30s presented for evaluation of a symptomatic left-sided acoustic neuroma and was found to have an incidental chronic subdural haematoma (SDH) over the left frontoparietal convexity without trauma or precipitating event. The SDH expanded on serial imaging and the patient eventually underwent left-sided frontoparietal craniotomy for haematoma evacuation. Haematological evaluation was benign, but angiography revealed absence of the anterior half of the SSS. We report the first case of spontaneous SDH in the setting of hypoplastic rostral SSS.

“…Despite careful observation, the exact cause of the ASDH and its original site were not identified in this case, although the existing condition of hypertension might have acted as a risk factor for the development of the hemorrhage. [ 3 , 4 ] Alternatively, based on intraoperative findings, Pacchionian granulation was thought to be a possible cause of the ASDH. Spontaneous resolution in a short period is known to be an infrequent but distinct phenomenon of ASDH, which is represented by dissemination and redistribution of the subdural hematoma.…”

“…[1,2,12] In contrast with trauma-associated ASDH, spontaneous or non-traumatic ASDH is thought to occur infrequently in association with a variety of pathological processes. [3,4,6] Here, we present a unique case of organized CSDH that transformed from a non-traumatic ASDH and became symptomatic for 2 weeks, exhibiting microvascular proliferation in the subdural clots.…”

Background: Despite extensive investigations, the exact etiology of chronic subdural hematoma (CSDH) remains elusive. Organized CSDHs are a distinct but less-understood type of CSDH. Case Description: A 50-year-old hypertensive woman experienced headache without any previous head injury. At presentation, the patient showed no focal neurological deficits. Cranial computed tomography (CT) revealed a slightly compressive subdural hematoma that spontaneously regressed and no intracranial vascular lesions. Cerebral magnetic resonance imaging identified a non-enhancing nodular lesion in the subdural hematoma. After the patient presented disorientation and aphasia on post hospitalization day 14, CT showed a considerable enlargement of the subdural hematoma. Partial removal of the bi-layered hematoma was performed through a parietal craniotomy. Histological examination revealed microvascular proliferation in both the outer membrane and the nodular lesion. On postoperative day 35, CT demonstrated a remarkable resolution of the residual hematoma. Conclusion: Development of microvascular proliferation in the clots of an acute subdural hematoma may lead to its rapid enlargement as an organized CSDH. Organized CSDH can be managed by partial removal of the outer membrane and hematoma through a craniotomy.

“…3 Risk factors for spontaneous acute subdural hematomas include vascular malformations, neoplasia, dural metastases, hypervitaminosis, hematological diseases (coagulopathy), spontaneous intracerebral hypotension, alcoholism, cocaine use, arterial hypertension, bleeding from cerebral artery aneurysms or cortical arteries. 3 Among all these, the arterial origin is the most found (60%). 4 Around 40% of patients with spontaneous acute subdural hematoma have hypertension and associated alcohol abuse.…”

“…There are few documented cases of spontaneous acute subdural hematoma without a history of traumatism. 3 Revelation clinical signs are often headaches, the investigations tools are CT scan and MRI and also angiography.

Background: Subdural hematoma is very often associated with head trauma. There are few documented cases of spontaneous acute subdural hematoma without a history of Case presentation: A 50-year-old man was admitted for a mild-intensity headache in helmet-like, which occurred in the night without any cause waking him up from his sleeping. He denied any drug taken, mainly anticoagulant, non-steroidal anti-inflammatory drugs. The neurological exam was absolutely normal. The head CT Scan performed showed a thick left fronto-temporal spontaneous acute subdural hematoma The blood investigations were normal. Brain angio-CT didn’t show any The patient benefited fromconservative treatment under observation and experienced a progressive regression of the headache throughout the hospitalization stay. He was discharged an eleventh day later. Conclusion: Spontaneous acute subdural hematoma is a rare entity. It requires painstaking clinical, biological, and imaging and a strict follow-up for its management.
