“…In some cases, neurological condition remained stable [8,10,17,21,28,33] or improved gradually [12,15,16,18,19,24,29,35] The death of one such patient reported by Balik et al had been correlated with hemodynamic instability and sudden cardiac arrest due to sympathetic hyperactivity. On postmortem examination of the above case, redistribution of hematoma in spinal subdural space and ischemic changes in the pons was detected.…”

Background: Traumatic acute subdural hematoma (ASDH) is an oft encountered entity in neurosurgery. While resolution of such thick SDHs usually takes time, certain cases of rapid spontaneous resolution have also been reported. This article attempts to review the pathophysiology, clinical and radiological features of such cases, as well as provide an insight into decision making for their management. Methods: Electronic literature search was done to look for similar cases of spontaneous rapid resolution of ASDH. Five of authors cases have been described. Their clinical and radiological features along with those of cases from literature search were tabulated and analyzed. Results: A total of 44 relevant cases were included for analyses. Of these, 39 cases were from 33 articles found in existing literature and 5 cases were from author's collection. The M:F ratio was 25:19 with a mean age was 41.84(SD-4.094) years. Twenty -six patients showed “Rapid” neurological improvement (24 hours) occurred in 10 patients. The mean hematoma resolution time on CT scan was 13.78 hours (SD 16.46) ranging from 1- 72 hours. Twenty-nine patients showed redistribution of hematoma, most commonly to tentorium and falx cerebelli. CT scan findings were classified into 5 types as per the nature of hypodensity around hematoma. The geometric mean time to resolution of hematoma was least for type 2 (7.27 hours) and type 1(7.52 hours) patients. Conclusion: Selected patients of ASDH with rapid neurological improvement and specific CT findings may show spontaneous resolution of ASDH. Multicentric studies with larger study population may provide better insight into the nature and outcomes of such entities.

Rapid Spontaneous Resolution of Large Acute Subdural Hematoma

Usually, acute subdural hematomas (ASDHs) result from head trauma and require urgent surgical treatment. However, there have been many reports of rapid spontaneous resolution of ASDHs since 1986. Recently, we experienced a case of a massive ASDH that resolved spontaneously within 1.5 days. A 76-year-old man was admitted to a local hospital after a head injury. According to his clinical records, his initial neurologic status was good (Glasgow Coma Scale score of 14). However, his head computer tomography (CT) scan demonstrated a massive ASDH to the right, with a significant midline shift. Based on his neurological status and general condition, surgery was not considered, and the patient was closely monitored in the intensive care unit. The next day, the patient was transferred to our hospital as requested by his family, after which his neurological state stabilized, and the customary follow-up brain CT was performed. It was about 32 hours after the patient's head injury, and it revealed an unexpected finding, near-total resolution of the ASDH. Herein, we review previously reported similar cases and relevant mechanisms of rapid resolution of the ASDH. We believe that neurosurgeons should comprehensively assess the patient's condition and CT findings and provide appropriate treatment, especially when surgical intervention is unnecessary.
