BACKGROUND: Ischioanal fossa epidermoid cysts are uncommon masses of epithelial origin and are believed to be either congenital or the result of trauma. Surgical excision is preferred as opposed to incision and drainage because these masses may enlarge, recur, become infected, or undergo malignant transformation. CASE: This report describes a case of a 62-year-old woman who presented for evaluation of vaginal and perineal discomfort and fullness. Physical examination and computed tomography scan revealed a 7...

Malformations of the rectum and urinary tract frequently coexist, and the prevalence of urogenital defects in patients with a rectal defect ranges from 20 to 54%. In most patients, anorectal malformations are diagnosed and treated surgically in early childhood. In this report, we present a case of a 52-year-old male with a history of urological operations in infancy due to a congenital urethral malformation and multiple recurrent episodes of perineal abscesses with urinary retention. Anorectal endosonography and magnetic resonance imaging revealed the presence of a large cystic lesion adjacent to the rectal wall which became smaller at the level of the puborectalis...

Ikram Hussain, Tiing Leong Ang
Pancreatic lymphangiomas are rare, but benign neoplasms. Historically, the diagnoses in various case reports were mostly made after surgical resection. There are emerging data concerning the utility of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to differentiate it from more sinister pancreatic cystic neoplasms. A confident preoperative diagnosis with EUS-FNA is crucial to avoid unnecessary workup or surgery, especially for small and asymptomatic lesions. Here, we present a rare case of asymptomatic pancreatic lymphangioma which was diagnosed with EUS-FNA...

One-third of tuberculosis cases affect the musculoskeletal system. Solitary bone tuberculosis is a rare condition in infancy, has non-specific findings, and can be misdiagnosed easily. Cystic form tuberculosis may mimic many other pathologic conditions. In our case report, we present tuberculosis osteomyelitis of the distal tibia in a baby aged ten months who visited our outpatient department with swelling and pain in their left ankle. Curettage and debridement was performed twice for the lesion. An under-knee splint was applied for 3 months and anti-tuberculosis treatment was given for 12 months...

BACKGROUND: A ranula is a cystic lesion in the floor of the mouth, formed either as a retention cyst or pseudocyst as a result of extravasation of mucus in the surrounding tissue. It may be treated by micro-marsupialization, marsupialization or excision of lesion with or without the associated salivary gland. Marsupialization is usually achieved by cutting a slit and thereafter stitching the edges such that the epithelium of the exterior becomes continuous with that of the interior of a cyst...

Due to the low incidence of the Ewing's Sarcoma (ES) family tumors, the available epidemiology is likely to be unreliable, and at present, there are no standard diagnostic or clinical guidelines outlining their management. This report describes a case of peripheral primitive neuroectodermal tumor (ES/pPNET) which initially mimicked cystic lesions, and describes a comparison between ES and ES/pPNET in the jaws by the World Health Organization classification. This review addressed 63 cases published in the English literature between 1950 and 2016...

A 61-year-old Asian man presented with severe right upper quadrant pain which had been worsening for several months. Laboratory results indicated elevated aspartate aminotransferase and alanine aminotransferase. The subsequent ultrasound, CT and MRI showed a large cystic mass with solid components and severe intrahepatic and extrahepatic biliary ductal dilatation. The mass was resected and pathology showed a well-demarcated mucinous cystic lesion with polygonal cells containing ovoid nuclei and abundant pink oncocytic cytoplasm...

A 67-year-old man with a slow-growing, asymptomatic perianal lesion was presented to the colorectal clinic. Physical examination and radiological investigation were suggestive of an externally prolapsing colonic polyp. However, intraoperative findings of a cystic lesion containing a thick brown substance questioned the initial diagnosis. After complete surgical resection of the encapsulated lesion, histological examination revealed a tailgut cyst (cystic hamartoma). These uncommon lesions originate from an embryological remnant of the hindgut...

Posttubercular adhesive arachnoiditis is a rare, late complication of tubercular meningitis. Syringomyelia can develop as a consequence of intramedullary cystic lesions and cerebrospinal fluid (CSF) flow disturbance around the spinal cord, even after successful chemotherapy. We reviewed the literature related to posttubercular syringomyelia treatment and suggest a new combined surgical approach. A 25-year-old Nigerian male patient presented with legs numbness, urinary disturbance, and legs weakness. Spinal magnetic resonance revealed a T5-T7 syringomyelia, secondary to adhesive spinal arachnoiditis related to a history of tuberculous meningitis...

Astrocytomas are responsible for 30% of all primitive intramedullary tumors with cervicothoracic predominance. However, only about one hundred cases of intramedullary pilocytic astrocytomas were described. The authors described the case of a 69 year-old patient presenting with a broad-base gait, bilateral pain and dysesthesia of inferior limbs with a diagnosis of an intra-axial cystic lesion centered to the conus medullaris, diagnosed as pilocytic astrocytoma of conus medullaris (PACM) after surgery. To the best of our knowledge, only two previous reports concerning PACM were made...

Markus Preis, Travis Bailey, Lucas S Marchand, Alexej Barg
BACKGROUND: In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES: (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS: Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center...

An aged mixed-breed goat doe was presented with a 9-mo history of serosanguineous vaginal discharge. Vaginal speculum examination revealed serosanguineous discharge but otherwise no abnormalities. Transrectal ultrasonography showed normal ovaries and multifocal cystic lesions within the uterus. Ovariohysterectomy was recommended because of a strong suspicion of neoplasia. Multiple, non-resectable masses were noted in and around the uterus intraoperatively, and euthanasia was elected. Autopsy revealed multiple masses within the uterus, cervix, and lung parenchyma...
