Case Reports
Intramedullary spinal cord metastasis of renal cell carcinoma 6 years following the nephrectomy.
Intramedullary spinal cord metastasis is an uncommon manifestation of systemic tumor. We present a case of metastatic mass inside the thoracic spinal cord 6 years after nephrectomy because of renal cell carcinoma. ⋯ The case shows that renal cell carcinoma has the possibility of metastasis into spinal cord even several years after nephrectomy. Any symptom of neurological deficit should alert to a possible intramedullary spinal cord metastasis.

Dermoid cysts are rare benign congenital tumors comprising 1.1 % of the spinal tumors, with lumbosacral region and cauda equina being the common sites. Many cranial cases with spillage of cyst contents into the subarachnoid space have been reported. ⋯ However, there is no consensus for the treatment of the syrinx cavity. Observation of similar cases would give us more information about treatment options and the progression of these lesions.

The chondroma originated in falx cerebri and dural convexity is very rare, less than 30 cases reported so far. Here, we report a case of 26-year old male, with a huge mass at fronto-parietal falx cerebri, who was misdiagnosed as parafalcine meningioma on preoperative MR imaging. ⋯ By reviewing the MR images of the patient, we find that the peripheral ring-like enhancement and intratumoral partial slight coral-like enhancement on contrast-enhanced T1 images might be the valuable MR features to differentiate from parafalcine meningioma. In addition, the tumor's pathogenesis and pathological characteristics were briefly discussed.

One of the clinical presentations of intracranial aneurysm is unilateral oculomotor nerve palsy (ONP). The most common location is the posterior communicating artery. Surgical clipping and/or endovascular coiling of the aneurysm are the treatments. The aim of this study was to identify the factors that influence the postoperative recovery of patients who have posterior communicating aneurysm with ONP. ⋯ Early decompression of the posterior communicating aneurysm yielded satisfactory recovery and ONP can be reversible. In our patients, the first component of oculomotor function to recover was the parasympathetic fibers.

To demonstrate the incidence of screw misplacement and revision rates in a group of 72 patients that underwent pedicle screw fixation for spinal pathologies using the conventional, fluoroscopy-guided open technique. ⋯ Conventional open technique in pedicle screw placement is a safe and sound method with its low and acceptable complication rates.
