Disseminated blood borne metastases from carcinoma of the gall bladder are uncommon and occur late in the course of the disease. Of all the distant sites that can be involved by the metastatic disease, the skeletal system is the least commonly involved. Skeletal metastasis in a case of carcinoma gall bladder is rare to find and when it is associated with solitary skull metastasis it is even rar...

introduction: ewing’s sarcoma is the second most common primary malignant tumor of bone found in children after osteosarcoma. it accounts for 4–9% of primary malignant bone tumors and it affects bones of the skull or face in only 1–4% of cases. hence it rarely affects the head and neck. subject and method: in this case report, we describe a case of primary ewing's sarcoma occurring in the tempo...

the primary carcinoma may secondarily invade bone tissue through direct extensions, blood circulation or lymphatic transportation particulary when it is arising from breast, prostate, kidney, thyroid and lung. metastatics tumors of bone are more common than primary tumor of bone. the most common tumor, which metastasizes into bone, is the breast adenocarcinoma. some metastatic tumors of bone in...

Nasopharyngeal carcinoma (NPC) is one of the commonest head and neck malignancies in South East Asia. The tumor arises from epithelial layer nasopharynx, found most frequently at Fossa Rosenmuller (FOR). NPC can spread to its adjacent structures cause distant metastasis. However, occurrence dura metastasis uncommon despite being closely located. Consequently, a lesion may be misdiagnosed as men...

BACKGROUND The differential diagnosis of skull base masses is diverse and includes benign and malignant neoplasms, vascular anomalies, congenital lesions, as well as infectious and inflammatory processes. Metastatic masses of the skull base are a rare manifestation of systemic malignancies. Breast cancer is the most common cause of skull base metastases. Villaret syndrome refers to cranial nerv...

Alveolar soft part sarcoma (ASPS) with skull and brain metastases is extremely rare. A 53-year-old patient diagnosed as skull metastasis of ASPS visited our clinic complaining of an outgrowing scalp mass in spite of radiation therapy. Past medical history revealed that the patient had been diagnosed and treated for ASPS of the thigh 4 years ago. Magnetic resonance imaging revealed a hyperintens...

Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...

Abstract Primary intraosseous meningioma (PIM) is a rare tumor that arises in the skull. Histopathologically, it generally described as slow-growing, benign lesion. However, on occasions, PIM presents malignancy with high proliferative ability, which requires maximal resection, adjuvant radiotherapy, and subsequent careful follow-up. Because of rarity such cases, they present diagnostic challen...
