Atypical fibroxanthoma is a pleomorphic spindle cell neoplasm characterized by a variable combination of cells with fibroblastic and histiocytic features. It occurs mostly on sun-exposed area of the head and neck of elderly person and is a clinically benign reactive lesion despite apparent malignant histologic features. However, because of its potential for metastasis, it is widely regarded as a low-grade sarcoma. We report a 30-year-old woman with atypical fibroxanthoma developed on the left occipital area. The lesion was $1.5{\times}2cm$ sized papule. There was no skin lesion such as ulcer or eschar. However, mass was involving occipital bone and composed of dense, pleomorphic spindle cells and several bizarre multinucleated giant cells. After wide excision of the scalp and occipital bone, the defect was covered with bone cement, bipedicled local flap and the donor site was covered with STSG. The wound healed completely without complication. It remained free of recurrence for a period of about 1 year follow up.

The purpose of this study was to investigate the effects of occipital bone stimulation by cervical stabilizing exercise on the muscle tone, stiffness, ROM, and cervical lordosis in patient with forward head posture(FHP). This study was a case study of a single patient with forward head posture. This study used a ABA' design, A and A' were the baseline phases and B was the intervention phase. The intervention was occipital bone stimulation by cervical stabilization exercise. It was administered once daily for 7 days. The therapist kept hands together, and placed the two index fingers under the subject's occipital bone. The subject performed the chin-in exercise with a maximum isometric contraction for 20 sec.The exercise was implemented by performing the movements 10 times as a set and repeating the set three times. The muscle tone was not significantly changed after intervention. However, the stiffness was decreased and lasted the effect lasted without intervention. The cervical flexion angle was increased, but the cervical extension angle was not significantly changed after the intervention. The left and right lateral flexion angles were increased and the effect lasted without any intervention. However, the left and right rotation angles were significantly changed after the intervention. Cervical lordosis increased not from $37^{\circ}$ to $41^{\circ}$ after the intervention. These results suggest that occipital bone stimulation by cervical stabilizing exercise had a positive effect on cervical stiffness, flexion and lateral flexion ROM, and lordosis in a patient with forward head posture.

Oblique basal skull fractures resulting from lateral crushing injuries involving both clivus and occipital condyle are rare due to their deep locations. Furthermore, these fractures may present clinically with multiple cranial nerve injuries because neural exit routes are restricted in this intricate region. The authors present an interesting case of basal skull fractures involving the clivus and occipital condyle and presenting with sixth and contralateral twelfth cranial nerve deficits. Clinico-anatomic correlations and the courses of cranial nerve deficits are reiterated. To the authors' knowledge, no other report has been previously issued on concomitant sixth and contralateral twelfth cranial nerve palsies following closed head injury.

Occipital alopecia after Open Heart Surgery under the Cardiopulmonary bypass is an uncommon minor complication. We had experienced Occipital alopecia in 6 cases after Open Heart Surgery. The cause of the alopecia was transient circulatory disturbance due to pressure effect of the patient`s head and intraoperative hypotension. The prodromal symptoms of the alopecia were erythema, itching, and watery discharge, but some patients showed non-specific symptoms. The common site of the alopecia was right occipital region and the size was 2-4 cm in diameter. The regrowth of the hair was completed at postoperative 3 to 5 months without specific treatment except conservative treatment. Fortunately the postoperative alopecia is a self-limiting condition, and spontaneous regrowth of hair is the rule without other complications.

Primary intracranial melanoma is uncommon. These tumors most commonly occur at the temporal lobe, cerebellum and cerebellopontine angle. We report a case of intracranial malignant melanoma of the occipital lobe in a 60-year-old man who presented with headache and visual disturbance. The mass showed hyperintensity on T1-weighted images and hypointensity on T2-weighted magnetic resonance images. He underwent gross total removal of tumor and received radiotherapy. Follow-up imaging studios showed neither recurrence nor any signs of residual disease for 4 months.

Ventriculoperitoneal [VP] shunt is a common treatment for hydrocephalic patients. However, complications, such as shunt tube occlusion, infection, intracranial hemorrhage, seizure can occur. Of these, intracranial hemorrhage may occur due to intracranial vascular injury or a rapid decrease of intracranial pressure [ICP]. Most of these hemorrhages are subdural hematomas [SDH] while a few are epidural hematomas [EDH]. It is extremely rare for an intracranial hemorrhage to occur due to an extension of the bleeding from an injured extracranial vessel. We report two cases of EDH due to occipital artery injury following VP shunt and extraventricular drainage [EVD].

Objectives : The purpose of this study was to examine the effects of electroacupuncture at GB14, on brain activity assessed on an electroencephalogram(EEG). Methods : (1) Thirty-four healthy participants were randomly divided into two groups, receiving either real acupuncture or non-penetrating sham acupuncture at GB14. (2) EEG measurements were conducted simultaneously before and after a 5-minute electroacupuncture stimulation, and the differences in the resulting EEG parameters were compared between the test and control groups. Results : (1) Absolute power increased significantly in the theta-wave channel of the occipital region and in the entire alpha-wave channel. (2) Relative power decreased significantly in the theta-wave channels of the frontal and occipital regions. (3) Coherence decreased significantly in the theta- and beta-wave channels of the parietal and occipital regions, and increased significantly in the alpha-wave channels of most areas. Conclusions : This study shows that electroacupuncture stimulation at GB14 activates the alpha frequency band in particular.

Suboccipital pain can be caused by problems relating to muscles, tendons, ligaments, joints, discs and nerves of the upper cervical structures. History taking, symptomatological evaluations and physical examinations, and even radiological studies are often unavailable when making an exact diagnosis for the treatment of cervicogenic headaches. Therefore, diagnostic blockades have recently become essential for the diagnosis and treatment of nonspecific cervicogenic headaches. A third occipital neurotomy was successfully performed after diagnostic blocks were administered to a patient who had suffered from suboccipital neuralgic pain and referred pain to the temporal and retroocular areas.

A C2-3 zygapophygeal joint is a major source of cervicogenic headache. Radiofrequency (RF) neurotomy is preformed widely for zygapophygeal joint pain. Conventional RF denervation technique is generally performed under fluoroscopic control. Recently, ultrasound-guided radiofrequency on zygapophygeal joint has emerged as an alternative method. We report our experiences of two successful ultrasound-guided pulsed radiofrequencies on 39-year-old and 42-year-old males, who complained occipital headache and posterior neck pain.

Jugular bulb diverticulum is an irregular extension of the jugular bulb into the temporal bone that may be symptomatic or asymptomatic. The jugular bulb has rarely been reported to extend into the occipital condyle; such extension is termed a condylar jugular diverticulum and is characterized as a defect in the occipital condyle contiguous with the jugular bulb. This report details 3 cases of condylar jugular diverticulum. Extension of the jugular bulb into the ipsilateral occipital condyle was noted as an incidental finding on cone-beam computed tomographic (CBCT) images of 3 patients. All 3 patients were asymptomatic, and this finding was unrelated to the initial area of interest. CBCT use is becoming ubiquitous in dentistry, as it allows 3-dimensional evaluation, unlike conventional radiography. Proper interpretation of the entire CBCT is essential, and recognition of the indicators of condylar jugular diverticulum may prevent misdiagnosis of this rare entity.
