Giant diverticulum of sigma.

We have carefully read the interesting article recently published in your journal about a giant sigmoid diverticulum. In our institution we have diagnosed two similar cases and we would like to contribute our casuistry.

Gastric obstruction secondary to abdominal re-herniation of a giant hiatal hernia. An illustrative case to understand the pathophysiology of gastric volvulus.

: To depict the characteristics of a special type of gastric volvulus caused by acute re-herniation of a previous hiatal hernia.: We present the case of a male patient with known history of a giant hiatal hernia who presented to our emergency department with a chief complaint of epigastric pain, oral intolerance and incoercible vomiting in the last 24 h. On suspicion of abdominal complication, an emergent computed tomography (CT) scan was performed.

'Back-and-Forth Stomach' CT Imaging Findings of a Pathophysiologic Entity Causing Acute Gastric Volvulus.

Background: Gastric volvulus (GV) is a life-threatening emergency condition that prompts emergent surgical management. With the advent of high-resolution computed tomography (CT), the role of radiologists in its diagnosis has become essential. Although many cases of GV have been described in the literature, its pathophysiology is still poorly understood.

[Findings of the (18)F-FDG PET-CT in a cardiac angiosarcoma complicated by a cardiac rupture].

Primary malignant tumors of the heart are a rare condition. The most common type is the cardiac angiosarcoma. The symptoms of this disease are very nonspecific and can be very difficult to diagnose by conventional imaging techniques.

Primary renal lymphoma: report of three new cases and literature review.

Objectives: We report the cases of three patients with primary renal lymphoma. Diagnosis and subsequent treatment are discussed.

Methods: The literature on the origin, epidemiology, clinical presentation, diagnosis, treatment and prognosis of primary renal lymphoma was reviewed.

[Pelvic lipomatosis. Diagnostic and therapeutic considerations apropos of 3 cases].

Objective: We report three cases of pelvic lipomatosis, and from them we discuss its diagnostic and therapeutic considerations.

Methods/results: Three patients, 71, 65 and 61 years old respectively, presented with irritative lower urinary tract symptoms. Intravenous pyelogram (IVP) and CT scan were performed as diagnostic procedures.
