Introduction: Pancreatic cystic lymphangioma (PCL) is an extremely rare benign tumor of lymphatic origin. Traditionally, it is diagnosed at surgery performed on a patient with a retroperitoneal cyst of unclear etiology. However, recently a few single case reports showed PCL was successfully diagnosed by endoscopic ultrasound with fine-needle aspiration (EUSFNA). Case Report: We present a new ca...

Introduction: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic.   Case Report: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT) scan. We resected the cystic ...

We report a rare case of schwannoma of the brachial plexus presenting as an enlarging cystic mass. A 52-year-old woman was found to have a rapidly enlarging cystic lesion in the left pectoralis minor space. Surgical exploration finally found that the lesion was schwannoma originating from the fascicles of the brachial plexus. Partial removal of the fluid enabled us to dissect the mass without d...

INTRODUCTION Lymphangiomatous cysts are submucosal masses that are rarely found in the gastrointestinal tract and more often in the neck, oral cavity, and skin. These cysts are benign tumors and mostly clinically silent. Symptoms include abdominal pain, diarrhea, and rectal bleeding. Their pathogenesis remains unclear. CASE PRESENTATION During a routine ultrasound examination of a Caucasian 2...

Second branchial cleft cysts are almost always located in the neck; thus, their presence in the nasopharynx is extremely rare. A 44-year-old man was referred to our department because a cystic mass was fortuitously found in the right lateral nasopharyngeal wall during transnasal esophagogastroscopy. He had suffered from intermittent right-sided nasal obstruction since childhood. T1- and T2-weig...

symptomatic mullerian duct cysts are uncommon. a young adult male presented to us with a palpable supra-pubic mass, pain and lower urinary tract symptoms. initial imaging modalities showed a large cystic lesion in the pelvis with a non-visualized right kidney. a short, blind ending right ureter on retrograde pyelography added to the confusion. on exploration, the lesion was noted to be separate...

INTRODUCTION Bladder outlet obstruction in younger men is often secondary to urethral stricture disease. In the older population it is often a result of benign prostatic hypertrophy. MATERIALS AND METHODS We describe the diagnosis, treatment, and outcome of a rare case of a Brunn's cyst causing bladder outlet obstruction in a 43-year-old male who was evaluated for obstructive urinary complain...

Parathyroid cyst is a very rare abnormality. The diagnosis can be made based on ultrasound and the analysis of the aspirated cystic fluid for parathyroid hormone (PTH). We report the case of a nonfunctional parathyroid cyst in a 50-year-old female patient with an anterior neck mass. The patient was complaining of pain in the anterior cervical region, dysphagia, dyspnea and dysphonia started thr...

A 12-year-old spayed female Labrador retriever was presented with forebrain signs. Brain MRI revealed a huge cystic lesion with the thickened falx in the frontal region. The brain parenchyma surrounding the lesion showed significant signs of a mass effect and also increased intracranial pressure. However, the dog suddenly became lucid after about two weeks, and an MRI scan one month after the i...

The majority of cystic squamous cell carcinomas (SCCs) of the neck have been shown to be metastatic tumors from tonsillar SCCs associated with high-risk human papillomavirus (HR HPV). Recent studies have demonstrated cytokeratin (CK)7 involvement in the development of HPV positive SCC, but no report has been issued on its simultaneous expression in primary tonsillar and metastatic tumor with cy...
