Article Abstract
Aneurysmal bone cyst (ABC) is a benign solitary lesion. It usually occurs in the long bones but uncommonly in the calcaneum, mandible, femur and clavicle. Its frequency of occurrence in skull and mandible is 4%, clavicle and ribs is 5%, femur is 13% and foot is 3%. Only a few cases of ABC of these unusual sites have been reported till date. Here we report four cases of ABC at unusual sites namely the calcaneum, mandible, femur and clavicle diagnosed primarily on the basis of different imaging modalities and later confirmed on histopathology.

Medullary thyroid carcinoma is a neuroendocrine tumor derived from thyroid C-cells. It is a rare aggressive tumor, known to metastasize to lymph nodes, liver, bones, and lungs. We report a case of a young patient with a family history of breast cancer, who developed breast metastases six months post-treatment for medullary thyroid carcinoma.

Renal cell carcinoma (RCC) has been known for its high propensity of metastasis to unusual locations, and jaw bones (JBs) are one among those sites. The literature has reported several studies analyzing metastatic tumors to the oral region, but very little research work has been published to date to analyze solely JB metastasis (JBM) via RCC. The goal of this study was to examine the published cases of metastasis to JBs from RCC as the sole primary source till date.

This case report discusses the management of a 75-year-old man who developed an unusual type of atypical atrial flutter following a previous pulmonary vein isolation for paroxysmal atrial fibrillation. Despite a second attempt to re-isolate the pulmonary veins and performing cavotricuspid isthmus ablation (which was suspected to be part of the arrythmia circuit), the flutter continued and was converted to sinus rhythm through electrical cardioversion. A few weeks later, the patient's atrial tachycardia relapsed.

Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal vascular malformations. Multiple SDAVFs are unusual and can occur either synchronously or metachronously, as reported in the literature. We report on the unusual case of a woman with three separate SDAVFs, which were surgically treated within the same setting; the postoperative course was characterised by unexplained repeated haematoma formation within the surgical sites.

In the field of quantum materials, understanding anomalous behavior under charge degrees of freedom through bond formation is of fundamental importance, with two key concepts: Dimerization and charge order at different cation sites. The coexistence of both dimerization and charge ordering is unusually found in NaRu2O4, even in its metallic state at room temperature. Our work unveils the origin of the interplay of these effects within metallic single-crystalline NaRu2O4.
