Successful management of cervical tuberculosis and severe kyphosis using polyetheretherketone expandable cage and titanium plate: A case report.

Key Clinical Message: Successful management of cervical tuberculosis and severe kyphosis was achieved using a PEEK expandable cage and titanium plate, demonstrating favorable outcomes in restoring cervical alignment and stability. This approach represents a promising alternative for addressing complex cervical pathologies, highlighting the potential of PEEK-based interventions in surgical management. Abstract: Cervical tuberculosis can lead to severe vertebral destruction and kyphosis, posing challenges in surgical management. Recent advancements, including the use of polyetheretherketone (PEEK) expandable cages and titanium plates, show promise in addressing multilevel cervical pathologies. This report details the successful treatment of a 27-year-old male with cervical tuberculosis and severe kyphosis. Surgical intervention involved prevertebral abscess evacuation, C5-C7 corpectomy, and insertion of a PEEK expandable cage with an anterior titanium plate. Postoperative care included a Philadelphia collar, and follow-up demonstrated restored cervical alignment and stability. The use of PEEK-based surgical interventions, as demonstrated in this case, represents a significant evolution in managing complex cervical conditions. The successful outcome highlights the potential benefits of PEEK expandable cages in addressing cervical tuberculosis and kyphosis. Further research is needed to validate these findings and establish PEEK-based interventions as a viable alternative in such cases.

Subarachnoid Hemorrhage Caused by Supratentorial Cerebral Cavernous Malformation: A Case Report.

Cavernous malformations (CMs) are acquired vascular abnormalities of the central nervous system that are typically asymptomatic. Clinically symptomatic lesions may present with seizures, intracerebral hemorrhage, or focal neurological deficits. Very rarely, CMs have been described as the cause of subarachnoid hemorrhage. We report a case of a previously healthy 58-year-old man who presented with acute onset of severe headache associated with vomiting. Head computed tomography (CT) scan showed subarachnoid hemorrhage with intraventricular extension. Subsequent CT angiography (CTA) and digital subtraction angiography (DSA) studies showed no evidence of vascular abnormalities. The patient was initially managed conservatively but later required neurosurgical and radiological interventions due to a complicated hospital course and worsening clinical condition. During surgery, an incidental mass was found in the temporal lobe, and subsequent histopathological examination confirmed the diagnosis of cavernoma, which was likely the underlying cause of the subarachnoid hemorrhage. This report highlights the importance of considering CMs in the differential diagnoses of subarachnoid hemorrhage, especially in the absence of informative results from CTA and DSA studies. Timely detection and management of CMs may positively impact the clinical outcome, leading to reduced morbidity and mortality rates.

A case study of the pathology on a rare case of scalp lymphangioma in an adult patient.

Lymphangiomas are congenital malformations of the lymphatic system, mostly well-circumscribed and cystic. Although many theories were proposed to explain etiology, it is still controversial. Most of these lesions are found in the cervicofacial region, while the scalp is considered a scarce location, with only a few reported cases in the literature. Herein, we report a case of scalp lymphangioma in a 33-year-old male, which unexpectedly and significantly progressed in size over one year. The MRI scan characteristics were unique compared to the literature description of the lymphangioma, as it appeared hypointense in both T1WI and T2WI with inhomogeneous contrast enhancement, eventually consistent with lymphangioma on histopathology. The patient underwent surgical excision of the mass without any recurrence over a follow-up period of 1 year.

Extensive Foreign Body Reaction to Synthetic Dural Replacement After Decompressive Craniectomy with Radiological and Histopathology Evidence: Observational Case Series.

BACKGROUND: Though the indications are quite varied, decompressive craniectomy is considered a life-saving procedure. Maximal effectiveness of craniectomy is achieved when, in addition to bone removal, the dura mater is opened properly and is augmented with duraplasty. Different synthetic materials have been used over the decades to replace the dura during decompressive craniectomy. We have used different synthetic dural replacements at our institution, including Neuro-Patch, DuraGen, and Lyoplant. In this case series, we described 4 cases that had excessive granulation tissue formation in response to a newly used synthetic dural substitute (ReDura) after emergent decompressive craniectomy. During follow-up brain imaging at different intervals, these cases were found to have foreign body reaction in the form of excessive granulation tissue formation; additionally, 1 case had a sterile pus-like collection. The granulation tissue diagnosis was affirmed by histopathology in all 4 cases. METHODS: This study was an observational retrograde case series, with data obtained from electronic medical records. RESULTS: The study showed extensive foreign body giant cell reactions on preoperative computed tomography scans, indicating a very high occurrence rate of 72.4%, when ReDura was used as dural replacement. CONCLUSIONS: Our experience showed that patients are prone to develop severe foreign body giant cell reactions with ReDura. Neurosurgical centers using this material should monitor patients for possible abnormal foreign body reaction and report it to establish the safety and efficacy profile of this material.

Obstructive hydrocephalus and facial nerve palsy secondary to vertebrobasilar dolichoectasia: Case Report.

BACKGROUND: Symptomatic hydrocephalus due to vertebrobasilar dolichoectasia is a rare occurrence. CASE DESCRIPTION: We report a patient who presented with acute confusion and vomiting. Neuroimaging revealed elongated and tortuous basilar artery indenting and elevating the floor of third ventricle causing obstructive hydrocephalus. Initially, the patient was treated with external ventricular drain and then with ventriculo-peritoneal shunt. CONCLUSION: We suggest prompt surgical intervention upon diagnosis as a first choice of treatment in order to avoid further complications.
