The diagnostic approach to a possible pancreatic mass lesion relies first upon various non-invasive imaging modalities, including computed tomography, ultrasound, and magnetic resonance imaging techniques. Once a suspect lesion has been identified, tissue acquisition for characterization of the lesion is often paramount in developing an individualized therapeutic approach. Given the high preval...

malignant tumors of pancreas are usually primary neoplasms and pancreatic metastases are rare findings. we are reporting a case of squamous cell carcinoma (scc) of the esophagus with pancreatic metastasis. a 59-year old woman was admitted with chief complaint of abdominal pain and mass. she was a known case of esophageal scc since 4 years before when she had undergone transthoracic esophagectom...

several lesions (inflammatory, neoplastic and congenital) can involve in the skull base. the role of imaging is to detect the location and extension of lesion, determine mass and mass like lesions, differentiate benign from malignant tumors, detect invasion to adjacent structures and make decision in surgical planning. skull base divides to anterior, middle and posterior cranial fossa and some ...

The authors describe a rare case of inflammatory pseudotumor involving the clivus, where a soft tissue mass lesion, with extension into the prevertebral retropharyngeal space and the cavernous sinuses, was detected by CT and MRI. The mass resembled a malignant tumor or aggressive infectious lesion, and the final diagnosis of inflammatory pseudotumor was a diagnosis of exclusion, decided after h...

An 82-year-old man was referred for endoscopic ultrasound of an ulcerated subepithelial mass in the duodenal sweep. The mass was initially identified during upper endoscopy for coffee-ground emesis. During endoscopic ultrasound, a 21-mm hypoechoic ulcerated subepithelial mass with a duct-like structure was identified. During suction to appose the lesion against the tip of the echoendoscope, the...

Mediastinal lymphangioma is primarily a benign lesion and the majority of the cases are found incidentally. These lesions account for approximately 1% of all mediastinal tumors. Here we present a giant mediastinal cystic mass in a 35-year-old female who was presented with severe respiratory distress. On the plain chest radiography and CT scan, a massive left pleural effusion with large paraster...

A five-year-old female African hedgehog (Atelerix albiventris) was referred for a one month growing oral mass. The hedgehog was quiet, alert and responsive, with a 1.00 × 1.50 cm ulcerated lesion on the mandible. The patient was staged with total body radiographs, hematological and biochemical analyses and the mass was biopsied under anesthesia. The excised tissue was reported to be a ...
