In demyelinating disease spectrum, tumor-like (tumefactive) demyelinating lesions (TDL) are rarely seen. Atypical imaging and clinical features of these lesions may cause misdiagnosis of tumor or abscess. ⋯ Although MRI, CSF and pathologic examination help in differential diagnosis of the mass lesions, close follow-up is still crucial for the definite diagnosis. A higher MS conversion rate was found in patients with a younger TDL onset age.

Burr-hole craniostomy is the most efficient and safe choice for surgical drainage of chronic subdural hematoma (CSDH). Although the twist-drill drainage is also relatively safe and time-saving, it carries the risk of inadequate drainage, brain penetration and hematoma formation. Our modified technique helps in avoiding bleeding and brain penetration. ⋯ Our modified technique of twist drill drainage is inexpensive, simple, safe and effective alternative technique in the treatment of CSDH.

Subthalamic nucleus (STN) deep brain stimulation (DBS) has become a well-accepted treatment for patients with advanced Parkinson's disease (PD). During surgical planning for DBS, the length of the STN is taken into account and verified during microelectrode recording (MER) intraoperatively. Here, we addressed the question to which extent the length of the STN measured with the T2 weighted MRI in the probe's eye view corresponded with the intraoperatively determined length of the STN with MER. ⋯ This means that the entry and the exit of the STN can be adequately estimated using the probe's eye view preoperatively.

To evaluate the effectiveness of invasive procedures in medically intractable genitofemoral and ilioingunal neuralgia. ⋯ For patients with medically intractable genitofemoral and ilioinguinal neuralgias, nerve blocks and neurectomies can be applied safely for pain control.

To investigate the factors related to the local recurrence-free survival time (LRFS) after surgical treatment of GCT of the sacrum and mobile spine combined with preoperative embolization. ⋯ Intralesional excision with preoperative embolization is a feasible choice for T1 tumors of the sacrum and mobile spine, but for T2 tumors, more aggressive treatment may be required. The choice of surgical treatment should be balanced between the complications and tumor recurrence.
