Craniovertebral junction (CVJ) hydatid disease, although rare, forms an important differential diagnosis of CVJ bony pathologies, especially in endemic areas due to the sheer volume of cases presented there. The authors report a rare case of CVJ hydatid disease mimicking a bony expansile tumor on imaging. ⋯ The authors conclude that in tropical regions, hydatid disease of the cervical spine should be considered in the differential diagnosis of patients presenting with high cervical compressive myelopathy, especially when associated with fever. Spinal hydatosis may mimic a bony lesion on imaging and should be kept in mind, as in addition to routine decompression, use of scolicidal agents and intact removal of cysts have a significant effect on reducing the recurrence rate and improving the outcome.

The common fibular nerve (CFN) is the most frequently injured nerve in the lower limbs. Surgical management is necessary in approximately two thirds of patients and includes neurolysis, suture, graft repair, or nerve transfer. The distal sural nerve is the preferred donor for grafting, but it is not without complications and requires a second incision. We sought to study the surgical anatomy of the lateral sural cutaneous nerve (LSCN) with the aim of repairing CFN injuries through the same incision and as a potential source for grafting in other nerve injuries. ⋯ LSCN harvest is a viable alternative for nerve grafting, especially for repairing short CFN injuries, thereby avoiding the need for a second incision.

Few studies have examined associations between vascular compression and postoperative pain relief in patients undergoing microvascular decompression (MVD) for treatment of medically refractory type 1 trigeminal neuralgia (TN). The authors sought to examine for associations between vascular compression and postoperative pain relief to determine the utility of preoperative magnetic resonance imaging (MRI) in surgical decision-making for TN. ⋯ The findings of lower sensitivity and poor interrater reliability of MRI, as well as a lack of association between compressive vessel and postoperative pain relief reported in this study, suggest the decision to pursue MVD for TN should be based more heavily on classic symptomatic presentation over preoperative evidence of vascular compression.

Surgical procedures via the posterior median or paramedian approach for lateral lumbar disc herniation require significant bone resection to reach the herniation. In contrast, posterolateral transforaminal full-endoscopic lumbar discectomy (FELD) allows direct access to the lateral disc herniation. This study aimed to determine the efficacy and safety of this procedure. ⋯ Successful clinical results were obtained with a few complications and improvements in the domains of JOABPEQ and NRS. Posterolateral transforaminal FELD for lateral lumbar disc herniations is an effective and safe surgical option with minimal invasiveness and sufficient decompression.

Gamma knife radiosurgery (GKRS) is often performed to treat brain metastases (BrMs). Widely referenced guidelines have suggested post-treatment imaging studies at 3-month intervals. However, clinicians frequently obtain magnetic resonance imaging (MRI) studies at <3 months after GKRS. ⋯ Early MRI (within 3 months) after post GKRS will frequently show adverse findings even in asymptomatic patients, more often in patients aged <65 years and patients with multiple treated BrMs. However, according to the nature of the adverse findings observed in our retrospective study, it is unlikely that the clinical outcomes would have been affected if the post-GKRS MRI studies had been deferred to 3 months after treatment. Our data support deferring post-GKRS MRI to 3 months after treatment in the absence of new neurological signs or symptoms.
