Lung cancer has been well documented to spread to bone and the axial skeleton after metastasis to adjacent organs. Bony metastasis is not, however, the typical presenting manifestation. The differential diagnosis for a tissue mass on the skull should warrant a workup for metastatic disease. Bony metastasis plays an important role in treatment and disease management. We report an exceptionally r...

Most malignant rectal tumors are histopathologically characterized as adenocarcinoma and generally metastasize to distant organs such as the lungs or the liver. Metastasis of rectal carcinomas to the skull is extremely rare. This study reports the initial diagnosis of rectal adenocarcinoma recurrence in a 65-year-old female with scalp metastasis. The patient's history indicated a colorectal ade...

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...

BACKGROUND A solitary skull metastasis from hepatocellular carcinoma (HCC) prior to diagnosis of the primary tumor without liver dysfunction is a very rare event. CASE PRESENTATION A 71-year-old male, without known liver disease, presented to our institution with a palpable occipital scalp mass. On brain magnetic resonance imaging (MRI), a highly enhanced and osteolytic skull tumor was observ...

Although thyroid carcinoma is a relatively common form of malignancy, metastatic spread to the skull is rare. Here, we report a case of papillary thyroid carcinoma with frontal and parietal metastasis. A 61-year-old Chinese woman presented with a one year history of a growing mass on the center of the frontal and parietal bone, initially thought to be meningioma. Biopsy of the skull base mass a...

Follicular carcinoma of thyroid is a well differentiated thyroid malignancy. It is slow growing in nature and tends to metastasize to remote organs in advanced stage by hematogenous route. Lung and bone are the two most common sites of metastasis. In most of the reported cases of follicular thyroid carcinoma metastasizing to the skull, metastases occurred long after the diagnosis and institutio...

BACKGROUND AND PURPOSE Metastasis to the skull is clinically important, but routine MR imaging offers moderate sensitivity for skull-metastasis detection in our experience. We sought to determine if diffusion-weighted MR imaging (DWI) could improve the detection of skull metastasis in patients with primary carcinomas that metastasized to bone compared with conventional MR imaging. MATERIALS A...

BACKGROUND Intra or peritumoral hemorrhage of brain and skull tumors sometimes presents as stroke. Skull metastasis of chondrosarcoma is relatively rare, and furthermore, a case of intratumoural hemorrhage of skull metastasis of chondrosarcoma has not been reported. CASE DESCRIPTION A 73-year-old man underwent right lower leg amputation in the past because of chondrosarcoma and was operated f...

Bone metastasis is the most frequent type of distant metastasis in nasopharyngeal carcinoma (NPC). In this study, we investigated the correlation between the skull base bone destruction and the distant bone metastasis in patients with NPC. A total of 449 cases with NPC who were diagnosed and had definitive radiotherapy from 2001 to 2006 were enrolled in this study. The skull base bone destructi...
