Intradiploic epidermoid tumors are uncommon and giant epidermoid with dural involvement is scarcer. We report a unique case of a giant frontal epidermoid tumor presenting without typical features of swelling or bulge in scalp. A 61-year-old male presented with the complaints of forgetfulness and headache. Contrast magnetic resonance imaging brain revealed a large left frontal epidermoid tumor. A tumor measuring 13 × 11 × 4 cm, involving the dura but sparing the brain parenchyma, was excised through left frontal craniotomy. Such a presentation of giant epidermoid tumor with dural involvement is highly unusual. Complete surgical excision is the final aim and vigilant follow-up for recurrence is a must., (Copyright: © International Journal of Health Sciences.)

Acoustic neuromas are the most common lesion in the cerebellopontine angle. The authors report a unique case of acoustic schwannoma, presenting in middle cranial fossa masquerading as meningioma in a 24-year-old man, presenting with headache and focal seizures. Contrast-enhanced MRI of the brain revealed a mass lesion of the right middle cranial fossa consistent with features of meningioma. Intraoperatively a well-defined tumor with attachment to anterior petrous bone was excised. In the immediate postoperative period, the patient developed right-sided hearing loss, which was proven to be retrochoclear hearing loss on brainstem evoked response audiometry. Histopathology findings were consistent with benign schwannoma. Acoustic schwannoma originating in an unusual location middle cranial fossa is a plausible explanation of such unusual occurrence. Such a case has never been reported in the literature., Competing Interests: The authors have no potential conflicts of interest to disclose., (Copyright © 2022 The Korean Brain Tumor Society, The Korean Society for Neuro-Oncology, and The Korean Society for Pediatric Neuro-Oncology.)

Background: The gravity of "second wave" of COVID-19 has effaced many new challenges in India; mucormycosis being a recent one. Diabetes mellitus (DM) is a known significant risk factor for mucormycosis. Here, we present our experience with rhino-orbital-cerebral mucormycosis (ROCM) during the "second wave of COVID-19" at a tertiary health care centre in North India., Methods: This case series includes four cases of ROCM that were managed by our neurosurgical team in view ofcerebral involvement., Results: All the cases with an exception of one (Case 1), had a history of treatment for COVID-19 pneumonia. Case 2, 3 had undergone functional endoscopic sinus surgery (FESS) and orbital decompression before the onset of cerebral involvement; Case 4 underwent FESS and cranial surgery in the same sitting. All the patients had a history of DM and all the cases treated for COVID-19 pneumonia had a history of treatment with corticosteroids. Two patients underwent surgery with the exception of one patient, who did not provide consent for the same. One patient expired before surgical excision could be attempted., Conclusion: Regular and intensive follow-up is the key in swift detection and management of ROCM in post-COVID patients. While surgical excision is advisable in the fungal lesion, it must be borne in mind that radical excision of cerebral lesions is associated with morbidity, delayed recovery, and prolonged ICU stay. Culture and sensitivity-based antibiotics should be used judiciously as fever is a common postoperative complication. Blood sugar monitoring and control of DM are paramount in this condition. Steroids should be avoided in the management of cerebral edema with judicious use of hypertonic saline or mannitol., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Surgical Neurology International.)
