Subdural empyema is a rare form of intracranial sepsis associated with high morbidity and mortality. The most frequent cause is extension of paranasal sinusitis through emissary veins or of mastoiditis through the mucosa, bone, and dura mater. Development of subdural empyema after pyogenic meningitis is known to be very unusual in adults. We report a rare case of fatal subdural empyema, an unusual complication of pyogenic meningitis. Our bitter experience suggests that subdural empyema should be borne in mind in patient with pyogenic meningitis who exhibit neurological deterioration.

Spinal intradural extramedullary non-infiltrated solitary metastasis is very rare. We report a case of intradural extramedullary carcinoma to the T9 nerve root, which mimiking a nerve sheath tumor. Pathology reveals metastatic adenocarcinoma. We discuss the feature of mechanism and pathogenesis and management strategy follows.

Although the spontaneous disappearance or decrease in size of a herniated disc is well known, that of a large extruded disc has rarely been reported. This paper reports a case of a spontaneous regression of a large lumbar disc extrusion. The disc regressed spontaneously with clinical improvement and was documented on a follow up MRI study 6 months later. The literature is reviewed and the possible mechanisms of spontaneous disc regression are discussed.

Isolated tuberculosis of the coccyx is extremely rare. A 35-year-old man presented with a 3-month history of coccygeal and gluteal pain. Computed tomography and magnetic resonance imaging revealed osseous destruction and a large enhancing mass involving the coccyx with anterior and posterior extension. Pathologic examination of the surgical specimen revealed necrosis, chronic granulomatous inflammation, and multinucleated giant cells consistent with tuberculosis. This case highlights the importance of considering tuberculosis as a diagnosis even though unusual sites are involved.

The authors present a case of multiple intracranial calcifications after the procedure of external ventricular drain placement in a 50-year-old man with pericallosal artery aneurysm. We believe that calcifications formed dust that had fallen into the track during the external ventricular drain procedure. The clinical features and radiological findings are presented with review of literature.

The incidence of distal anterior cerebral artery[ACA] aneurysm is relatively rare, and only a few cases of bilateral symmetrical distal ACA aneurysms which were adhered together have been reported. They are also called kissing aneurysms. We treated bilateral asymmetrical distal ACA kissing aneurysms in a 44-year-old woman. We successfully clipped the double aneurysmal sacs individually by interhemispheric approach in spite of intraoperative aneurysmal rupture. The patient was discharged without any neurological deficits two weeks after the operation.

We report the case of a patient with a retro-odontoid synovial cyst, coupled with os odontoideum and atlantoaxial instability. We observed the regression of the cyst after C1-2 transarticular screw fixation and posterior wiring without direct surgical excision of the cyst on the follow-up MR images, which were obtained two and three months postoperatively. The myelopathic symptoms and signs of this patient were resolved by degrees.

We report a case of early stress fracture of the pelvic ring following an extension of a multilevel instrumented lumbosacral fusion in an osteopenic female. Surgeons should be aware of possibilities of pelvic complications in osteopenic patients with lumbosacral arthrodesis and should take care when harvesting iliac bone graft.

Cerebrospinal fluid leakage may commonly occur during spinal surgeries and it may cause dural tears. These tears may result in hemorrhage in the entire compartments of the brain. Most common site of such hemorrhages are the veins in the cerebellar region. We report a case of hemorrhage, mimicking aneurysmal subarachnoid hemorrhage due to a cerebrospinal fluid leakage following lumbar spinal surgery and discuss the possible mechanisms of action.

Percutaneous epidural neuroplasty (PEN) is a known interventional technique for the management of spinal pain. As with any procedures, PEN is associated with complications ranging from mild to more serious ones. We present a case of intracranial subdural hematoma after PEN requiring surgical evacuation. We review the relevant literature and discuss possible complications of PEN and patholophysiology of intracranial subdural hematoma after PEN.
