Surgical corridors for congenital aural atresia with otogenic cerebellar abscess and lateral sinus thrombosis

The following is a case report of an adolescent with mental retardation who had congenital aural atresia with contralateral congenital facial palsy. She developed multiple intracranial complications (cerebellar abscess and lateral sinus thrombosis) due to cholesteatoma. We managed her in a multidisciplinary approach. This report discusses case management, emphasising the meticulous intraoperative steps taken in identifying the landmarks and precautions adopted to avoid postoperative facial palsy and other complications.

Case study of a sudden loss of vision in a diabetic patient: an unusual cause. Endogenous Klebsiella pneumoniae panophthalmitis and cerebellar abscess associated with pyogenic liver abscess

Background: Community-acquired pyogenic liver abscesses due to Klebsiella pneumoniae is increasingly recognized across the world with more incidence in East Asian countries. Cases of endogenous endophthalmitis secondary to pyogenic liver abscesses with K1 serotype K. pneumoniae have been reported in the literature. We report a case of endogenous panophthalmitis along with cerebellar abscess occurring in a newly diagnosed diabetic patient secondary to pyogenic liver abscess. Case presentation: A middle-aged male of east Asian descent presented with sudden onset right eye vision loss associated with fever. Workup revealed newly diagnosed diabetes mellitus, panophthalmitis, cerebellar abscess, and pyogenic liver abscess due to K. pneumoniae. The patient, unfortunately, underwent right eye evisceration. Conclusion: Endogenous panophthalmitis due to K. pneumoniae is a fatal complication and can result in blindness. Multiple foci of infection can be present in such cases. Thorough workup, prompt antibiotics as well as surgical treatment may improve prognosis.

Cerebellar abscess secondary to extradural internal protuberance epidermal cyst

An Intracranial epidermoid cyst is a rare congenital anomaly developed because of dysembryoplasia during the third to fifth week of gestation. We describe the unusual epidermal cyst which originating extradurally in internal protuberance in which causes cerebellar brain abscess. Neurosurgical intervention is advocated to prevent the ongoing risk of significant complications. Meticulous care was taken to grossly excised all the pathologic tissue to avoid recurrence.
