Calcified dural based meningioma, mimicker of metastasis on skeletal scintigraphy
1Department of Nuclear Medicine, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan.
Abstract:
Meningiomas are meningeal based slow growing tumours most of which are benign in nature. Calcification in these tumours leads to Technetium labeled Methylene Diphosphonate (Tc99m-MDP) uptake on skeletal scintigraphy. Hybrid SPECT-CT bone scanning offers anatomic details and differentiates between benign entity and metastasis. We present the case of a 56-years-old female with right breast carcinoma. Bone scintigraphy, acquired as a part of baseline staging work up, showed focal skull uptake mimicking skeletal metastasis. SPECT-CT scan demonstrated characteristic anatomic features of calcified meningioma in right parietal region.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
