INTRODUCTION: We present a case of ectopic intrathoracic multinodular goiter and correlate the magnetic resonance imaging appearance with the histological findings. CASE PRESENTATION: A 72-year-old man was referred to our institute with a two month history of cough. The chest radiograph showed a mass located in the mediastinum. A chest computed tomography scan, showed an enhancing mass at the right side of the middle mediastinum where magnetic resonance images, demonstrated a multicystic mass. The mass was excised through a right lateral thoracotomy and histologically it proved to be an ectopic multinodular goiter. CONCLUSIONS: Although ectopic intrathoracic multinodular goiter is a rare entity, it should be considered in the differential diagnosis of mediastinal masses. The preoperative diagnosis is important as, unlike substernal goiter which is surgically approached through the neck, the ectopic thyroid is treated by thoracotomy.
RESUMEN
Echocardiography represents an invaluable diagnostic tool for the detection of intracardiac masses while simultaneously provides information about their size, location, mobility and attachment site as well as the presence and extent of any consequent hemodynamic derangement. A 29-year-old asymptomatic young woman with incidental transthoracic echocardiographic (TTE) discovery of an aortic valve mass is presented. The 2-dimensional TTE showed a mobile, pedunculated mass, attached by a thin stalk to the aortic surface of the right coronary aortic cusp at the junction of its base with the anterior aortic wall. The importance of valve sparing tumour resection even in asymptomatic patients is emphasised.

INTRODUCTION: Primary malignant neoplasms of nerve sheath origin are rare, highly aggressive tumours that account for no more than 5% of all soft tissue sarcomas. In the head and neck where the great majority of peripheral nerve neoplasms are benign, as in the rest of the body, malignant peripheral nerve sheath tumours (MPNSTs) are unusual lesions. PATIENT: A case of a large MPNST is reported, which originated in the left temporalis muscle of a 74-year-old man who did not suffer from von Recklinghausen's disease. It had been treated as an abscess for a long time. DISCUSSION: The clinicopathologic properties of this neoplasm have been widely discussed and the emphasis is on the need for its early identification since the tumour's non-specific symptoms may result in delayed diagnosis and treatment. CONCLUSION: To date, to our knowledge, no case of MPNST located in the temporalis muscle has been described. The rarity of the tumour along with its clinical appearance and the vague symptoms may result in delayed referral and thus the tumour being quite large when diagnosed.

Adrenocortical oncocytomas are exceptionally rare. To our knowledge, only 23 cases have been reported in the world literature, most of which were benign and nonfunctioning. We report a case of adrenocortical oncocytoma diagnosed by pathological examination of an extirpated right adrenal mass in a young woman. We discuss this case and review the literature on this unusual entity.
