Littoral cell angioma, a rare cause of long standing anaemia: a case report

Littoral cell angioma is a rare primary splenic tumor that is difficult to differentiate preoperatively from other benign and malignant splenic lesions. We report a case of littoral cell angioma of the spleen in a 51-year-old woman that presented with long standing anaemia

Giant fibrovascular polyp of the oesophagus: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>We present a case of fibrovascular polyp, a rare submucosal tumour of the oesophagus that has been reported only sporadically in the literature. The biapproach for surgical removal of fibrovascular polyp has only been mentioned once in the literature.</p> <p>Case presentation</p> <p>A 65-year-old Greek man presented with a 9-month history of gradually progressive intermittent dysphagia. Radiologic work-up with oesophagogram and computed tomography revealed a large, sausage-shaped intraluminal polyp extending from the level of the cervical oesophagus to the level of the upper body of the stomach. The diagnosis of giant fibrovascular polyp was made radiographically and confirmed by endoscopic biopsy. The polyp was removed using a biapproach surgical technique: pharyngotomy and subsequent gastrostomy.</p> <p>Conclusion</p> <p>Fibrovascular polyp is a rare submucosal tumour. Proper treatment depends on accurate assessment of the origin, size, and vascularity of the pedicle and the size of the tumour. Choice of the appropriate surgical approach depends on the correct diagnosis, which can usually be indicated radiographically by the presence of a smooth, sausage-shaped defect with a discrete bulbous tip.</p

Brucella liver abscess; imaging approach, differential diagnosis, and therapeutic management: a case report

We report a new case of a brucellar liver abscess (brucelloma) in a young woman without previous remote brucellosis who presented with pronounced systemic and mild local symptoms. Brucelloma is the result of calcification of a granoulomatous reaction induced by persistent Brucella in macrophages. It represents a rare manifestation that follows previously undetected brucellosis. We describe the findings in plain radiograph, ultrasound, computed tomography, and magnetic resonance images. Together with the positive serology, imaging yielded important elements supporting the diagnosis. Modern radiological techniques also contributed to the final therapeutic management, preventing unnecessary laparotomy. Sequencing confirmed the definite diagnosis of Brucella melitensis as the causative factor

Successful management of bulky osseous metastasis of renal cell carcinoma with selective arterial embolization and radiofrequency ablation: a case report

The case of a 64-year-old male patient who presented with a bulky osseous tumor metastasis from renal cell carcinoma is reported. The metastatic lesion extended from the acetabulum of the left iliac bone into the iliosacral joint

Imaging findings of an epidermoid cyst undergoing malignant transformation

Malignant transformation of epidermoid cyst into squamous cell carcinoma (SCC) is rare. We report the case of a 39-year-old woman presenting with dizziness and cerebellar ataxia. MR scan revealed a mass in the left cerebropontine angle compressing the brainstem and the cerebellum, with two main components, a cystic and a solid one. The cystic component displayed imaging findings consistent with an epidermoid cyst. The solid component showed dense calcifications, low signal intensity on T1W, T2W and DW images and peripheral nodular enhancement. MR spectroscopy detected high lipid/lactate peaks and choline/creatine ratio. Imaging findings raised suspicion for malignant transformation, which was confirmed by histopathologic examination revealing an SCC. MR imaging with intravenous administration of gadolinium, DW images and MR spectroscopy can play a critical role in the diagnosis of malignant transformation of an epidermoid cyst

Magnetic resonance imaging findings in pseudo-Meigs' syndrome associated with a large uterine leiomyoma: a case report

<p>Abstract</p> <p>Introduction</p> <p>Pseudo-Meigs' syndrome is a rare pathological entity characterized by the presence of a pelvic mass other than an ovarian fibroma. The mass is associated with ascites with or without hydrothorax.</p> <p>Case presentation</p> <p>We describe the case of a 41-year-old Caucasian woman with a large uterine leiomyoma associated with massive ascites. A magnetic resonance imaging scan showed a large subserosal leiomyoma with multiple areas of cystic degeneration.</p> <p>Conclusion</p> <p>To the best of our knowledge, this is the first reported case of pseudo-Meigs' syndrome caused by a uterine leiomyoma and diagnosed using magnetic resonance imaging. The pathophysiology of this syndrome and the role of magnetic resonance imaging are emphasized in this case report.</p

Primary Extra-gastrointestinal Stromal Tumor of Retroperitoneum

Background Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract. More rarely neoplasms with histology and immunohistochemistry similar to GISTs may occur outside the gastrointestinal tract (omentum, mesentery and retroperitoneum) and are so-called Extra-gastrointestinal Stromal Tumors (EGISTs). EGISTs arising in the retroperitoneum are extremely rare: to date, only 58 cases have been reported in the literature. Case Report We herein report a case of a primary EGIST of the retroperitoneum surgically treated. The pre-operative radiological evaluation showed a retroperitoneal mass, placed in left paravertebral region. Results Morphological and immunohistochemical features led to a diagnosis of extra-gastrointestinal stromal tumor (intermediate-low risk form). Conclusions As a result of the rarity of reports of primary EGISTs of retroperitoneum we need to analyze the data of reported cases in order to gain a better understanding about the pathogenesis, prognosis and optimal treatment of this disease

Thick calcification from a GIST of the stomach penetrating into pericolic soft tissue - report of a case

Thick calcification is a rare presentation of gastrointestinal stromal tumor (GIST). Penetration into gastric mucosa and pericolic soft tissue has never been reported. We report a case of gastric GIST with cystic degeneration and thick calcification in an 81-year old female, who presented with hematemesis and severe abdominal pain. Thick calcification of this tumor penetrating into pericolic soft tissue was noted and successfully treated by distal gastrectomy and partial colectomy. For gastrointestinal tumors with thick calcification, even with benign behavior, surgical intervention should be considered for both oncological considerations and prevention of catastrophes like perforation or penetration into surrounding soft tissue
