Stereotactic biopsy is a well-established procedure in neurosurgery. Our objective is to define the clinical, radiological, and technical factors that can condition the emergence of postbiopsy symptomatic intracranial hemorrhage. Based on our findings, we suggest recommendations to improve its usual clinical practice.

We made a retrospective study of 429 cases with stereotactic biopsies performed in the past 37 years. The surgical procedure-was adapted in terms of the stereotactic frames (Todd-Wells, CRW, Leksell), neuroimaging tests, and planning programs available in the hospital. Fifty-three variables were analyzed for each patient (SPSS.23).

The diagnostic yield was 90.7%. Forty-one patients (9.5%) suffered a symptomatic postbiopsy hemorrhage; only 17 (3.9%) had permanent morbidity. The mortality was 0.93% (
= 4). A postsurgical CT scan was requested only in 99 patients (23%) of our series. Lesion mass effect, cystic component, contrast enhancement, histological nature, or number of targets were nits after the procedure is a useful strategy, the request for control CT scans should be conditioned by the clinical evolution of each patient.
With the increase in endovascular treatment, reports of embolism other than thrombus are scattered, but intracranial tumorigenic embolism is rare and difficult to diagnose. Here, we describe a case of a tumorigenic embolism in a patient with lung cancer whose invasion into the vascular system was not detected on preoperative whole-body imaging.

A 66-year-old man who was hospitalized to undergo radiotherapy for pulmonary carcinoma suddenly developed left hemiplegia. He exhibited atrial fibrillation, and emergent radiographic examination revealed a right middle cerebral artery occlusion. Urgent mechanical embolectomy was performed, with successful revascularization. The excised embolus had a unique morphology and was pathologically diagnosed as a cerebral embolism caused by pleomorphic pulmonary carcinoma.

Tumor-derived cerebral embolism is extremely rare, but it is necessary to consider it as a potential source of embolism during differential diagnosis in patients with malignant tumors.

is a species of Gram-negative enteric rod found in normal human gut flora. Pathologically, this most often presents as urinary tract infections, wound infections, and bacteremia. It is highly uncommon for
to be implicated in a central nervous system infection, with only 12 reported cases of parenchymal abscesses or meningitis.

A previously healthy 13-month-old female presented with fever of unknown origin and had a witnessed seizure during evaluation. A large left subdural fluid collection was identified, and the patient underwent emergent burr hole drainage and subdural drain placement. Cultures demonstrated
empyema, and she subsequently completed a course of directed antibiotics. Six months following surgery, she has no further clinical or radiographic evidence of infection, seizures, or neurological sequelae.

We describe the first reported case of isolated subdural empyema caused by
. The child was successfully treated with the evacuation of the empyema and direct antibiotics with no lasting neurological injury.

Tentorial meningiomas attached to the inner edge of the tentorium are difficult to excise due to their deep location. Sufficient space may not be always available through a subtemporal approach. Thus, the aim of not retracting the brain is not fulfilled.

To gain surgical corridor, we electively resected the inferior temporal lobe. This helped in greater working space, better visualization, and less chances of venous damage.

Employing this technique of elective temporal lobe resection helped us in complete tumor removal without compromising on vision or surgical corridor.

A limited inferior temporal lobectomy greatly enhances the working space and vision in cases of difficult tentorial meningiomas. This translates into ease of tumor excision without compromising the patient safety.

Gunshot wound (GSW) injuries to the spinal column are correlated with potentially severe neurological damage. Here, we describe a GSW to the thoracolumbar junction (e.g., T12/L1 level) which resulted in a cauda equina syndrome that resolved once the bullet was removed.

A 29-year-old male presented with a T12-L1 GSW; the bullet traversed the right chest and liver, entered the spinal canal at T12, and then settled at L1. He experienced excruciating burning pain in the right lower extremity/perineum and had urinary retention. On neurological examination, he exhibited severe weakness of the right iliopsoas/quadriceps (2/5) and extensor hallucis longus (1/5) which had decreased sensation in the right lower extremity in all dermatomes and urinary retention. The myelogram showed the bullet lodged intrathecally at L1; it compressed the cauda equina. Immediately after, the bullet was extracted and at 8 weeks follow-up, the patient's right-sided motor function normalized, the sensory findings improved, and the sphincteric dysfunction resolved; the only residual deficit was minimal residual numbness in the L2-L5 distributions.

Twenty percent of penetrating spinal column injuries are attributed to GSW s. The location of these injuries best determines the neurological damage and degree of recovery. Since patients with incomplete cauda equina syndromes have favorable prognoses, removal of bullets involving the T12-S1 levels may prove beneficial.
