Intraoperative electrocorticography-guided resection of the epileptogenic zone in an unusual porencephalic cyst: case report and literature review.

Introduction: Porencephalic cysts resulting from perinatal artery infarctions typically manifest as large cysts accompanied by pre-existing neurological deficits. A small porencephalic cyst without any neurological deficit is a rare cause of medically refractory epilepsy. Case presentation: A 23-year-old female presented with a history of medically refractory epilepsy secondary to a small right parieto-temporal porencephalic cyst. Despite optimal anti-seizure medications, seizures persisted. Surgical intervention was planned, and intraoperative electrocorticography (ioECoG) was used to delineate the epileptogenic zone (EZ), which was found to be two gyri posterior to the cyst. Discussion: Very focal ischaemia resulting in a small porencephalic cyst from perinatal artery infarction exhibits a distinct organization of the EZ involving wider area posteriorly indicating involvement of arterial territory distal to the cyst. This contrasts with the typical perilesional EZ observed in other lesional epilepsy causes. Conclusion: Our findings emphasize the need to consider aetiology during interpretation of ioECoG to better define the electrophysiological border between the normal and epileptogenic brain, aiding in achieving a better surgical outcome.

Pioneers of Neurosurgery in the South Asian Association for Regional Cooperation (SAARC) Region: A Historical Vignette and Beyond.

South Asia, consisting of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka, spreads between the Himalayan base and the Indian Ocean and shares identical geophysical characteristics. With the inclusion of its newest member Afghanistan, these 8 member nations of the South Asian Association for Regional Cooperation (SAARC) share more or less a homogenous geographical, political, and historical background and cultural heritage, with a significant role in shaping the world. This densely populated area is home to around a quarter of the world's total population. From the ancient ages, the neurosurgical practice has paced relentlessly and in the last 100 years, it has reached its zenith. With modern advancements, neurosurgery has developed in its diagnostic and treatment modalities along with facilities for training and education. Despite falling behind owing to economic, educational, and geopolitical constraints, the pioneers of the SAARC region have established the fields of neurosurgery in their respective countries with command. No constraint could stop them from educating and training young physicians to make competent neurosurgeons to evolve the field of neurosurgery in their countries. Their firm determination and hard work paved the way to keep this field striving and thriving, to serve a substantial volume of the world population with their neurosurgical insight and skill. However, this region needs to go a long way as the number of neurosurgeons and facilities is still insufficient. This can be achieved with the guidance and collaboration among the neurosurgeons of the SAARC region as the youth here are talented and hardworking.

Intra thecal baclofen pump as an ad hoc measure for a case of severe tardive dystonia refractory to multiple lesioning.

Tardive dystonia is an infrequent ailment in patient reliant with chronic antipsychotic medication. The front-line envoy in the treatment of this illness is set into motion with oral agents including baclofen, benzodiazepines, and other antispasmodics. Regardless of an extensive therapy, the patients are not able to control of their spasticity/ dystonia. The authors reported a case of severe tardive dystonia treated with baclofen therapy in a patient frigid to medical therapy and multiple lesioning. Case Report: A 31-year-old female, diagnosed as a case of depressive illness and being managed with neuroleptic medications, who went onto develop tardive dystonia progressively worsening over a 4-year duration. After a comprehensive and meticulous evaluation of her neurological and psychological stratum, globus pallidus interna lesioning was reputed as the best course of action. As intended, staged lesioning was executed bilaterally with a trivial resolution eventually succumbing into recurrence, compelling a repeat lesioning. It was inaptly discouraging to see her crippled with the plight. Determined, not to give upon her, a way out with a baclofen therapy was proposed. A test dose with a 100 mcg of baclofen with an increment up to 150 mcg over a 3-day period demonstrated a promising prospect. On that account, the insertion of the baclofen pump was performed with an outstanding aftermath in her neurological endeavor. Clinical Discussion: Tardive dystonia is believed to be caused by striatal dopamine receptor super-sensitivity persuaded by the dopamine-antagonizing action of antipsychotic drugs. The first line of treatment being oral agents including oral baclofen, benzodiazepines, and antispasmodics. If the patient suffers from an early-onset primary generalized dystonia, then treatment with deep brain stimulation of the globus pallidus interna is the approved and preferred treatment approach. Recurrence of the symptoms despite of multiple lesioning can be overcome by intrathecal baclofen pump infusion as stated by many research. It is not uncommon to face complications in such a procedure, but the benefits outreach the risk, which makes it a choice of treatment. Conclusion: The use of a continuous intrathecal baclofen pump for cases with tardive dystonia refractory to conventional therapy, it has been approved as one of the safest and capable procedures.

Unusual case of spontaneous bilateral basal ganglia bleed.

Hypertension is the most prevalent determinant condition embarking on the development of spontaneous intracerebral hemorrhage. Usually, the presentation is a unilateral hematoma. Spontaneous bilateral intracerebral hemorrhage is an outstandingly infrequent context, and not a lot of cases have been reported till date. Ensuing hypertension, trauma inflicted on the brain case is another common cause that out turn into the sequelae of bilateral intracerebral hemorrhage. Lately, a few cases of bilateral basal ganglia bleed have been revealed, as a repercussion of COVID-19 infection. Globally, <40 such cases have been reported. A 39-year-old man presented with complaints of acute onset of weakness of right half of the body. Additionally, facial deviation was noticed by his family members. He then sought medical help from a local healthcare center where CT scan of head was advised. Unexpectedly, the scan demonstrated bilateral intracerebral hemorrhage. He was then managed conservatively with oral medications and rehabilitation. The course of his hospital stay was uneventful and was eventually discharged after 9 days. He then presented to our institution for further evaluation. Thereupon, he had slurring of speech but was able to walk with minimal support. Simultaneous Bilateral Basal Ganglia Hemorrhage (SBBGH) is an exceptionally rare ailment. This genre of cerebrovascular accident embraces a comprehensive span of morbidity and mortality. In an acute setting, CT scan of head is the most relevant imaging modality. Nonetheless, MRI is the gold standard for definitive diagnosis and should be performed urgently to further typify and delineate the lesion.
