Objective And Importance: Only two cases of primary intracranial myxomas have been described previously in the literature: one patient had a primary intracranial myxoma in the pituitary fossa, and the other patient's myxoma was located in the posterior fossa.
Clinical Presentation: A rare case of primary myxoma of the temporal bone in a 17-year-old boy is described. The patient presented with a history of progressive left-sided hearing loss and increasing headaches of a few months' duration.
Intervention: An initial draining procedure in the left ear revealed extant mucous material, and further investigation showed a large calcified lesion involving the petrous and temporal bones and filling the middle fossa. At surgery, a large mucoid-appearing tumor was removed. The tumor pathology revealed a primary myxoma with bone and meningeal involvement. No clinical or histopathological evidence that it was a metastatic lesion was found.
Conclusion: The features of myxomas on computed tomographic and magnetic resonance imaging, the histopathology, and surgical considerations are discussed.

Rationale: Aggressive angiomyxoma (AAM) is an exceptionally rare mesenchymal tumor that predominantly manifests in the female genital organs during the reproductive age. Its rarity alone makes it a fascinating subject for study. The diagnosis of AAM necessitates differentiation from other benign or mesenchymal tumors and can be confirmed through immunohistochemistry (IHC) staining.

Background: The differential diagnosis of cardiac myxomas (CM), the most common benign primary cardiac tumors, is broad and a thorough diagnostic workup is required to establish accurate diagnosis prior to surgical resection. Transthoracic echocardiography (TTE) is usually the first imaging modality used for diagnosis of suspected CM. In a single tertiary centre study, we sought to determine the accuracy, sensitivity, and specificity of TTE in the diagnosis of CM and to determine echocardiographic characteristics indicative of CM.

Left atrial myxoma is the most prevalent primary cardiac tumor, known for its high risk of systemic embolization. Although surgical excision remains the standard treatment, options are limited for high-risk patients. This case report introduces a novel approach using transcatheter electrosurgery to address a left atrial myxoma via a transseptal approach in a patient ineligible for conventional surgery due to the heightened risk of intracranial hemorrhage associated with cerebral amyloid angiopathy.

Papillary fibroelastomas (PFEs) followed by cardiac myxomas (CM) are the 2 most common primary benign cardiac tumors. Although typically asymptomatic, they can manifest with nonspecific symptoms such as dyspnea and dizziness or more acute manifestations such as embolic events. We describe an unusual location of a PFE typically seen with a CM.

Cardiac myxomas are the most common primary intracardiac tumors and are histologically benign. However, they are potentially dangerous because of the risk of systemic embolism. Echocardiography is the key diagnostic tool for atrial myxomas, allowing for the identification of the tumor, as well as determining its location, shape, size, and connections with adjacent cardiac structures.
