Brain herniation and subsequent complications following partial resection of high-grade glioma: A case report.

Key Clinical Message: This case highlights the need for tailored strategies to address issues like brain herniation, subdural hygroma, and cerebrospinal fluid leak, which, if not managed promptly, can lead to long-term neurological deficits. Additionally, the role of specialized facilities in delivering highly specialized care for managing such intricate cases cannot be understated. Abstract: Decompressive craniectomy-induced subdural hygroma (SDH) frequently coexists with external cerebral herniation, resulting in neurological impairments. The incidence of brain herniation through a craniectomy defect postoperatively is 25%. Brain herniation (BH), SDH, and cerebrospinal fluid leak require urgent neurosurgical management as they can lead to irreversible long-term neurological deficits. We report a case of a 42-year-old male who presented with headache and grand mal seizures. He was diagnosed with herniation of brain parenchyma through the surgical defect with a displacement of the bone flap by a heterogeneously enhancing lesion in the left parietal lobe along with SDH in the left frontoparietal region post partial resection of high-grade glioma. In this report, we discuss the pathogenesis and management strategies of brain herniation, wound infection, cerebrospinal fluid (CSF) leak, ipsilateral SDH, floating bone flap, and communicating hydrocephalus in an adult patient following partial resection of high-grade glioma. This particular case emphasizes the value of an individualized patient-centered surgical approach to minimize the risk of postoperative complications.

Renal Tumours Of Non-Clear Cell Histology; 10 Years' Experience In A Specialized Centre.

BACKGROUND: Non-clear cell renal cell carcinomas are uncommon renal tumours with diverse histologically and genetically defined entities. Due to limited clinical outcomes data, no standardized management approach can be offered to these patients. This study aimed to analyse outcomes of non clear cell renal cell carcinoma after surgical resection of localized renal tumours in our population. METHODS: Patients with renal tumours who underwent partial or radical nephrectomy at the Department of Urology, from January 2010 to December 2019 were identified and evaluated, in terms of prevalence, presentation, recurrence, and survival outcome. RESULTS: Non-clear cell tumours were found in one-fourth of the total number of nephrectomies performed during this period for renal cell carcinoma (RCC). The mean age was 50.48±14.76 years (range 18-89 years) with 57% being of the male gender. The predominant types were chromophobe RCC, papillary RCC, and sarcomatoid RCC, in all non-clear cell renal tumours. Mean Recurrence Free Survival (RFS) for all tumours was 75.26±2.7 months. The projected 5 years RFS of papillary RCC, chromophobe RCC and sarcomatoid RCC were 94.2%, 84.3% and 62.5% respectively. CONCLUSIONS: RCC of non-clear-cell histology depicts excellent survival in patients with localized renal tumours. Furthermore, sarcomatoid RCC has worse recurrence free survival followed by chromophobe RCC and papillary RCC, in our population subset.

Multifocal myxopapillary ependymoma and iatrogenic spinal cord herniation: Management options and lessons learned.

Although myxopapillary ependymoma is a fairly common tumour of the lumbosacral spine, primary multi-focal myxopapillary ependymoma is a rare variant. Drop metastasis and leptomeningeal spread in the craniospinal axis is seen more frequently in the paediatric population, although it is unusual in adults. Surgical resection of the primary lesion remains the standard treatment. As per the authors' knowledge, to-date there is only one prior case in literature reporting iatrogenic spinal cord herniation with indentation after surgery for thoracolumbar spinal tumour. Here, we are discussing an unusual case of primary multi-focal ependymoma in a 16-year-old Asian boy, with drop metastasis and lepto-meningeal disease, who developed iatrogenic spinal cord herniation after the first surgery for the primary tumour. He presented to the Shaukat Khanum Memorial Cancer Hospital & Research Centre (SKMCH & RC), Lahore, after his first surgery. He underwent the definitive corrective surgery at SKMCH & RC where he was managed further. We discuss the management options for this patient and the lessons learned along the way.
