It is most commonly associated with sinusitis, typically affecting young males. The presence of pneumocephalus without trauma or surgery is exceedingly rare and should raise concern for intracranial infection. Early diagnosis through neuroimaging and prompt multidisciplinary intervention are crucial for preventing morbidity and mortality.  \nCase Report: We present a case of SDE and atraumatic pneumocephalus in a 76-year-old woman who was found unresponsive at home. Laboratory tests revealed leukocytosis, elevated inflammatory markers, and fever. Non-contrast computed tomography (CT) showed a 2-3 mm subdural collection with intracranial air foci, along with evidence of otitis media, mastoiditis, and pansinusitis. Lumbar puncture revealed xanthochromic cerebrospinal fluid (CSF) with elevated protein and white blood cells (WBC). Streptococcus pneumoniae was confirmed by CSF culture and urine antigen. She underwent emergency craniotomy, draining 75 cc of purulent material, followed by the ear, nose, and throat (ENT) intervention with maxillary antrostomy, ethmoidectomy, and tympanostomy. She experienced a full neurological recovery.  \nConclusions: This case underscores the importance of high clinical suspicion and early imaging in elderly patients with altered mental status and sinus pathology. Atraumatic pneumocephalus in non-surgical patients may signal severe intracranial infection. Timely, multidisciplinary management led to rapid recovery, and this case adds to the limited literature on pneumococcal SDE with pneumocephalus in elderly women with chronic sinusitis.  \nKeywords: Craniotomy • Empyema, Subdural • Infections • Pneumocephalus • Sinusitis •  \nStreptococcus pneumoniae  \nFull-text PDF: [https://www.amjcaserep.com/abstract/index/idArt/949999](https://www.amjcaserep.com/abstract/index/idArt/949999)  \n2018  —  6  22  \nPublisher’s note: All claims expressed in this article are solely those of the authors and do not necessarily represent those of their affiliated organizations, or those of the publisher, the editors and the reviewers.
