An unusual case involving an infected hepatic cyst in which the correct diagnosis was made without operation is reported. A 93-year-old woman presented with acute onset of right upper quadrant abdominal pain, mild left lower quadrant abdominal pain, diarrhea, and fever. On admission, computed tomography revealed a 15 cm solitary hepatic cyst in the anterior-superior segment of the liver with a ...

INTRODUCTION The spontaneous rupture of an infected renal cyst is a rare event. Spontaneous rupture with drainage to the exterior through a surgical scar has not been reported previously. CASE PRESENTATION A 49-year-old male with tetraplegia had undergone extended right pyelolithotomy in 1999. Deroofing and marsupialisation of a cyst in the upper pole of the right kidney was performed in 2003...

In regard to arthroscopic treatment of popliteal cysts, we explored the refuted pathology for popliteal cysts proposed by others. Here we introduce an arthroscopic technique using posterior portals to treat a popliteal cyst based on our observation that the opening of the cyst in the joint is a slit-like structure in the posterior wall of the capsule. By disrupting this slit-like structure with...

BACKGROUND The canal of Nuck is an embryological vestige of the processus vaginalis, and presents a potential site for endometriosis seeding. Hydroceles in this region are a rare cause of inguinal swelling in females. In addition, endometriosis localized to the canal of Nuck is exceedingly rare. CASE PRESENTATION A 44-year-old Japanese woman presented with a painful mass overlying her right p...

PURPOSE To assess the efficacy of percutaneous unroofing in the treatment of simple renal cysts instead of laparoscopic decortication and open surgeries. MATERIALS AND METHODS From November 2009 to October 2010 at our department, 11 patients with 12 simple cyst units were managed by percutaneous unroofing. All cysts were evaluated with ultrasonography and abdominal computed tomography. If the...

Alimentary tract duplications are epithelial-lined cystic or tubular structures attached to bowel wall and supplied by mesenteric vessels. Association between intestinal malrotation and duplication cyst, especially of jejunal location is rarely mentioned in literature [1-5]. We are reporting a rare coexistence of isolated jejunal duplication cyst and malrotation in a neonate with intestinal obs...

This report describes a spontaneous hybrid cyst in a Sprague-Dawley (SD) rat. A 52-week-old, male SD rat had a cutaneous cyst on the left mystacial pad. Histologically, the cyst wall showed infundibular differentiation with keratohyalin granules in the granular layer and matrical differentiation comprising basaloid epithelial cells with trichohyalin granules. The cyst cavity was filled with lam...

This report is composed of two patients with anteriorly located cervical intradural arachnoid cyst and review of 24 cases in Englishlanguage literature. Both of our patients were in the first two decades of life with neck pain and motor weakness. With suspicious diagnosis of anterior arachnoid cyst surgery was carried out in both cases, though laminectomy in one and laminoplasty in the other. T...

A 34-year-old woman presented with history of headaches, vomiting and progressive left hemiparesis for the last 3 months. CECT showed right frontal juxtaventricular, cystic lesion with an enhancing mural nodule and focal wall (Figure 1a). On MRI, the cyst was hypointense on T1WI (Figure 1b) and hyperintense onT2WI (Figure 1c) and suppressed on FLAIR sequence (Figure 1d). Per-operatively, a cyst...

An epidermoid cyst of the cecum is extremely rare; only eight cases have been reported in the literature. A 63-year-old woman was admitted to Kyung Hee University Medical Center with a colonic mass that had been discovered incidentally during a regular health check-up. The radiographic impression was that this mass was a gastrointestinal stromal tumor. During surgery, an exophytic mass in the c...
