In a case report Lili Chen *et al.* from the Neurology Dept, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou Guangyu Ying *et al.*, Yucong Peng *et al.*; Neurosurgery Dept, Second Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou published in the Clinical Case Reports Journal to highlight spontaneous intracranial hypotension (SIH) as a diagnostic pitfall in recurrent subdural hematoma (SDH) and to demonstrate the efficacy of targeted epidural blood patch (EBP) prior to surgical drainage. In non‑elderly patients with SDH and no trauma or obvious risk factors, SIH should be suspected. A targeted EBP may resolve the CSF leak and prevent recurrence, possibly avoiding or supplementing surgical intervention 1).
The case underscores an underrecognized etiology (SIH) in SDH, offering a valuable shift in differential diagnosis.
– Novelty: It adds to limited case literature by emphasizing targeted EBP efficacy specifically in recurrent SDH associated with SIH.
– Limitations:
