P126 LAPAROSCOPIC TREATMENT OF HYDROCELE IN FEMORAL CANAL: A CASE REPORT

Aim The hydrocele of the femoral canal (Femorocele) is one of the rarest entities of femoral hernia (1). All of the reported cases were an intraoperative diagnosis and were treated with an open approach. We are reporting, the probably first femorocele diagnosed and treated laparoscopically. Material and Methods A 57-years-old female patient was presented in our outpatient clinic with pain and an unclear lump in the groin area for 6 months. The sonographic examination revealed a cystic structure in the groin area resampling Nuck’s cyst. An elective laparoscopic exploration and transabdominal preperitoneal (TAPP) repair was planned. Results A laparoscopic exploration was carried out. Intraoperatively, the cystic structure was not found in the Nuck’s Canal, but in the femoral canal as a content of a femoral hernia with some pre-peritoneal fat. By the extraction of the cyst, a gush of clear fluid was noted. After the usual preparation of the preperitoneal area, a mesh was placed in TAPP technique. Conclusions This rare variety of femoral hernias, femorocele, is commonly misdiagnosed as a strangulated hernia or Nuck’s cyst (as in this case) among other differential diagnoses (2). All published femorocele cases were treated with an open approach. As demonstrated here, such unclear cases can be laparoscopically explored and treated accordingly.

Maxillary Dentigerous Cyst with Double Wolf Teeth in a 3-Year-Old Quarter Horse Mare

Dentigerous cysts are characterised by the formation of cysts containing dental material with a variable level of development. They are the result of a distinct embryological phenomenon. Usually, they are of significant clinical relevance in horses, especially in tandem with ectopic tooth. Contrarily, supernumerary teeth or typical polyodontias usually have limited impact. In this case report, we describe the occurrence of a supernumerary first premolar (Triadan 105). Dissimilar to known scientific literature however was the formation of a cystic structure around the supernumerary tooth. Surgical removal of the dentigerous cyst is discussed, as are the possible causes for the formation of the cystic structure. Based on this case report, we suspect that the formation of a cystic structure may not be limited to atypical polyodontias, as they may also occur in supernumerary teeth.

A Case of Torsion in an Otherwise-Normal Ovary with a Giant Hematosalpinx Larger than Enlarged Ovary: Utilization of Diagnostic Laparoscopy for the Accurate Diagnosis

We report a case of torsion in an otherwise-normal ovary with a giant hematosalpinx. A 23-year-old woman presented with complaints of abdominal pain and nausea. At initial visit, there was few abnormal findings of imaging tests, and we made a diagnosis of ovarian hemorrhage. Three days later, she came back with increased symptoms, and we detected the mass of a complex solid cystic structure with a unilocular cyst much larger than solid component. A diagnostic laparoscopy was performed immediately, and we could make a diagnosis of torsion in an otherwise-normal ovary with a giant hematosalpinx. We performed a salpingectomy and could preserve her ovary. This is the first case of torsion in an otherwise-normal ovary with a giant hematosalpinx which enlarged to a greater extent than the ovary.

L’Ambulatorio protetto: visitare ai tempi del Covid-19

A 3-months baby comes to our emergency department for an abdominal mass of elastic consistency that suddenly appeared for a week and grown exponentially in the last few days. Blood examinations identify a septic state of the child, and the emergency CT recognizes the abdominal mass’s cystic structure. The surgical removal and the histological analysis will confirm the diagnosis of Infected Common Macrocystic Lymphatic Malformation. This case allows us to remember to pediatricians the main features of Cystic Lymphatic Malformations that should always be considered during the differential diagnosis of abdominal masses of sudden onset in an infant.

P706 LMCA and LAD coronary ectasia in an asymptomatic young patient reassessment with multimodality imaging after 17 years

A 25 years old male patient was referred to an advanced center because of 2/6-degree systolo-diastolic murmur heard at meso-cardiac area during his pre-military routine examination. ECG revealed T wave inversions at standard D1 to D3 and precordial V1 to V4 leads, treadmill was non-diagnostic for ischemia. In his transthoracic echocardiogram, measurement of heart chambers and wall thicknesses were within normal range with normal wall motion of the left ventricle, EF was 55%. 2D and color-Doppler echocardiography revealed a cystic structure with venous flow in it at the right ventricular apex, and created a suspicion of a fistula. Myocardial perfusion scintigraphy showed ischemia at the apical sections of the septal wall. He underwent coronary angiography, LMCA and proximal LAD were ectatic, LAD ectasia was in consistent with the first septal branch, circumflex (Cx) and right coronary artery (RCA) angiograms were normal. LAD flow was examined and no fistula was detected. Right and left ventriculography revealed normal ventricular functions, oxygen saturations were 70.9% in pulmonary artery, 70.4% in right ventricle, 72.9% in right atrium, and 97.4% in the aorta. Pulmonary capillary wedge pressure was 10 mmHg, pulmonary artery pressure 10/26/5 mmHg, right ventricular pressure 13/6 mmHg, left ventricular pressure 120/0/8 mmHg. Further investigations for etiology and congenital malformations were planned and the patient was discharged with oral anticoagulant therapy. The patient had no contact with the outpatient clinic for 17 years. At the 17th year of the diagnosis he was called and reevaluated. He was still asymptomatic and oscultation findings were the same. Transthoracic 2D and 3D and color-Doppler echocardiography revealed the same cystic structure at the right ventricular apex, but this time with no-flow. Coronary CT angiography was performed, LMCA was ectatic and the diameter was 8.1 mm, proximal LAD was ectatic and the diameter was 6 mm, ectasia was in continuous with the first septal branch. The ectatic septal branch was at the apical level of the right ventricle, appearing like a cystic structure with a diameter of 2.8 cm, and the lack of contrast enhancement was thougt to be in consistent with thrombus formation. Cx and RCA artery calibrations were found to be normal. In order to confirm the diagnosis of thrombus formation, MR angiography was performed. Perfusion MRI showed no evidence of thrombus in the ectatic septal branch. Abstract P706 Figure.

Mucus Retention Cyst of the Soft Palate in a Dog

ABSTRACT A 10 yr old 6.6 kg (14.5 lb) castrated male Chihuahua was referred to the Alta Vista Animal Hospital for evaluation of a mass of the soft palate. The cystic structure was bluntly dissected from the soft palate submucosal tissue, and the dog recovered from surgery and anesthesia without complication. Histopathology revealed salivary tissue with a large multiloculated cyst lined by a single layer of cystic and dilated cuboidal epithelium. Follow up 7 mo after surgery revealed complete resolution of clinical signs with no evidence of local recurrence. To the authors' knowledge, this is the first confirmed report of a mucus retention cyst in a dog.

Urachal Cyst in a Bitch

Background: The urachus is a tubular structure continuous with the urinary bladder and the allantois in foetal mammals. It serves as a communication between these two structures. At birth, it loses its function and undergoes atrophy by fibrous proliferation within the lumen. When this atrophy process fails at some point, congenital anomalies of the urachus occur. These anomalies are rare in animals, and to our knowledge, the urachal cyst has not yet been described in dogs. The present work is unique in that it reports a case of this congenital defect in a dog. Our aim is to increase awareness and to discuss the clinical presentation, the imaging techniques used, and the final diagnosis of this anomaly.Case: A bitch Pit Bull, 3-year-old, was presented for veterinary assistance to investigate recurrent pseudopregnancy and an irregular estrous cycle. The animal presented in good bodily condition, and the white blood count and clinical biochemistry were normal. At ultrasound, 2 tubular structures, filled by an echogenic fluid mimicking uterine topography, were found extending through the umbilical and hypogastric regions. No alterations in structure, echogenicity or echotexture of the other organs were observed, including the ovaries and uterus. On exploratory laparotomy, a cystic structure was found, with 2 segments: the larger one was on the left side, attached to the apex of the bladder by its caudal portion; the other was on the right side, attached to the spleen by its cranial portion and to the apex of the bladder by its caudal portion in connection with the left segment. The ovaries, uterus and uterine horns showed no macroscopic alterations. The structure was removed, and after analysis (macroscopic morphology, wall histopathology and biochemistry of the contained fluid), it was determined to be a urachal cyst. The animal recovered uneventfully.Discussion: Ultrasound is an important tool for the evaluation of reproductive cycle physiology and its pathologies. At first, the owner’s complaint justified a fairly straightforward evaluation and clinical management of pseudopregnancy in a very healthy animal based on the history and clinical and complementary exams. However, ultrasound examination revealed two tubular structures filled with echogenic fluid in the lower abdomen. This made the case more complex, as these were interpreted as uterine horns by three different veterinarians, leading to the possibility of pyometra. The management of this condition must be cautious, since the animal's condition could rapidly deteriorate, necessitating an exploratory laparotomy. Based on the clinical presentation, macroscopic anatomy, fluid biochemistry and histological evaluations, the diagnosis of urachal cyst was proposed. Congenital anomalies occur when the urachus fails to obliterate. Four types can be found: patent urachus, urachal sinus, urachal diverticulum and urachal cyst. The urachal cyst occurs when the urachus encompasses a cyst-like structure that is closed to the umbilicus and the bladder lumen. The urachus becomes a cystic structure since its epithelium is still intact, active and accumulating fluid, like the one analysed in this report. Most urachal cysts in humans remain asymptomatic, but when infected, they can cause focal or diffuse peritonitis and an acute abdomen. Although rare, urachal cysts can develop malignant transformation. The combination of nonspecific symptoms and the infrequent occurrence of this anomaly make its diagnosis a difficult challenge. It is commonly an incidental finding like the case reported here. Therefore, diagnostic imaging techniques, especially ultrasound, are essential for the diagnosis. To our knowledge, this is the first case report of a urachal cyst in a dog. This rare anomaly of the urachus was an incidental finding in the investigation of the reproductive problems of a female dog.

Congenital Myoepithelial Carcinoma of Soft Tissue Associated With Cystic Myoepithelioma

Myoepithelial neoplasms of soft tissue represent a heterogeneous group of lesions, encompassing both benign entities as myoepithelioma (ME) and highly aggressive tumors as myoepithelial carcinoma (MEC). We describe a case of pediatric soft tissue MEC with peculiar features that may lead to misdiagnosis: congenital onset and presence of a benign component with predominant cystic structure. Few cases of congenital MEC have been reported, but the coexistence of MEC with ME is even more rare, accounting for less than 1% of myoepithelial tumors. Moreover, an extensive cystic appearance had never been described in either ME or MEC of soft tissue. Despite several predictors of poor prognosis, the patient has been showing a favorable clinical course since the administration of ICpE (ifosfamide, cisplatin, and etoposide) chemotherapy. This report provides valuable information in the differential diagnosis of cystic congenital tumors and supports a possible efficacy of adjuvant combined treatment for patients with localized disease after surgery.

Neurenteric Cyst Presenting with Bleeding Per Rectum

Neurenteric cyst in the thoracic cavity may produce a myriad of clinical features. We report a 7-month-old girl who presented with significant bleeding per rectum. On imaging, a mediastinal cystic structure with air-fluid levels was evident with cervico-thoracic vertebral anomalies. The cyst was excised and histopathology showed intestinal mucosal lining with heterotopic pancreatic tissue confirming the diagnosis of neurenteric cyst.
