RESUMO

Vascular cystic adventitious degeneration (CAD) is a rare disease of unclear etiology that affects mainly the popliteal artery (up to 85-90% of cases). Clinical manifestations are similar to aneurysm of the popliteal artery. CAD occurs mainly in males of the 4th and 5th decades of life (range 10-77 years). These patients usually have no risk factors of cardiovascular diseases. Unilateral symptoms prevail. We report a review and a 46-year-old patient with CAD of the popliteal artery.

RESUMO

La tortícolis es un signo clínico definido por la inclinación lateral del cuello y rotación de la cabeza, que puede ser fija o flexible y acompañarse o no de dolor cervical. Aparece en trastornos de diferente complejidad. Ante un caso de tortícolis, es preciso realizar una historia clínica cuidadosa y un examen físico completo, y, en caso de ser persistente, solicitar pruebas de imagen.Se hace referencia a una causa de tortícolis no descrita en la literatura. Se trata de una tumoración quística compresiva en la fosa craneal posterior, quiste de la bolsa de Blake, en una lactante pequeña diagnosticada mediante ecografía en la consulta de Pediatría de Atención Primaria. Tras el diagnóstico, se remitió al centro hospitalario de referencia, donde se intervino de urgencia por Neurocirugía Pediátrica, mediante fenestración de la tumoración por ventriculostomía endoscópica y derivación ventrículo-peritoneal. Actualmente, se encuentra asintomática y sin secuelas.


Torticollis is a clinical sign defined by the lateral inclination of the neck and rotation of the head, which can be fixed or flexible and accompanied or not by cervical pain. It appears in disorders of different complexity. In a case of torticollis it is necessary to carry out a careful medical history and a complete physical examination and, if persistent, request imaging tests.Reference is made to a cause of torticollis not described in the literature. This is a compressive cystic tumor in the posterior cranial fossa, Blake's pouch cyst, in a small infant diagnosed by ultrasound in the Primary Care Pediatrics office. After diagnosis, she was referred to the referral hospital, where emergency intervention was performed by pediatric neurosurgery, by fenestration of the tumor by endoscopic ventriculostomy and ventriculo-peritoneal shunt. She is currently asymptomatic and without sequelae.

RESUMO

In this article we report a series of cases with a cystic appearance clinically which were diagnosed as surprising entities histologically. The aim of presenting these cases is to demonstrate the importance of always sending clinically-appearing 'cysts' to pathology, because even the most experienced clinicians can be fooled by these lesions.

RESUMO

In mares, endometrial cysts are associated with endometriosis and can cause maternal recognition failure or compromise and delay pregnancy diagnoses. Historical treatments were invasive and had adverse effects on the endometrium. Hysteroscopically guided laser therapy is easy and effective for endometrial cysts resection, with no deleterious effects for the endometrium. A 110 cm long and 1.0 cm wide endoscope is sterilely introduced in the uterus through the open cervix of an estrous mare after vulvar cleaning. The uterus is slowly infused with less than 1 L of physiologic solution and the laser fiber is inserted in the biopsy canal of the endoscope. Cysts are then cauterized with the 980 nm diode laser with a contact fiber set at 20‒2 5W in continuous mode. Each cyst is punctured until complete voiding of the cyst and shrinking of the cyst wall around the fiber. Uterine lavages with sterile saline solution are performed directly after the surgery and for one or two days as non-inflammatory fluid can be observed. This procedure is easy and quickly performed, with no obvious deleterious effects. Cysts resection makes ultrasound pregnancy diagnosis easier and, in some cases, could restore proper embryo migration in the uterine horns between day 6.5 and 17. However, this treatment does not improve the underlying histological lesions related to endometriosis. These considerations should be clearly expressed to the breeder before this procedure.

RESUMO

BACKGROUND: Megalencephalic leukoencephalopathy with subcortical cysts (MLC), or Van der Knaap disease, is a rare spongiform leukodystrophy that is characterized by macrocephaly, progressive motor dysfunction, and mild mental retardation. It is very rare for mental illness such as psychotic disorders, affective disorders and anxiety disorders to occur in MLC. CASE PRESENTATION: A 17-year-old boy was admitted to our hospital after he developed symptoms of depressive state with catatonia after being diagnosed as having MLC with confirmed MLC1 mutation. His catatonic symptoms were improved with administration of olanzapine and sertraline and he was discharged after 4 months. Several months later, he became hypomanic. He was diagnosed with bipolar II disorder. Mood swings were controlled with the administration of carbamazepine. CONCLUSIONS: This case is the first report of bipolar disorder during the clinical course of MLC. This case indicate the possibility that MLC influences the development of bipolar disorder in MLC, however, further studies involving more patients are required to clarify this.

RESUMO

RATIONALE: Tailgut cyst (TGC) is a rare congenital disease that originates from residues of the tail intestine during the embryonic period. Most TGCs are benign lesions and the malignant transition is very rare. PATIENT CONCERNS: A 50-year-old woman attended our department complaining of defecation difficulty for more than 2 months. She reported irregular defecation with a small amount of liquid stool, 3 to 4 times per day. DIAGNOSIS: Biochemical analysis showed high levels of carcinoembryonic antigen (79.89 ng/mL; normal, 0-3 ng/mL) and carbohydrate antigen 199 (57.60 U/mL; normal, 0-35 U/mL). Abdominal computer tomography and magnetic resonance imaging showed a large cystic mass with enhanced signals. Post-surgical histopathology indicated that the mass was a TGC with adenocarcinoma transition. INTERVENTIONS: The cyst was completely resected. Symptomatic treatment was further performed, and the patient recovered well. LESSONS: We reported a rare case of a large TGC with adenocarcinoma transition. CT, MRI, and histopathology are important to diagnose TGC. Complete surgical resection is the first choice to treat TGC.

RESUMO

INTRODUCTION: Intestinal duplications are rare malformations and hail sites are the most common. Today, the diagnosis is made in antenatal because of the performances of antenatal ultrasound. OBSERVATION: This was a 15-month-old male infant received for constant crying, vomiting and increased abdominal volume that had been evolving for two weeks. An abdominal ultrasound was performed and objectified an intraperitoneal cyst formation of 30 x 27 mm, surrounded by a stratified wall and contiguous to a digestive loop. Surgery was performed and confirmed the existence of non-communicating ileal duplication. CONCLUSION: Intestinal duplication is a rare malformation. Ultrasound is often sufficient for diagnosis based on the presence of a characteristic double-walled cystic mass.

RESUMO

CASE: A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver. CONCLUSION: Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.

RESUMO

Primary malignant fibrous histiocytoma, now classified as pleomorphic undifferentiated sarcoma, is the most common soft-tissue sarcoma in adult life. Primary splenic pleomorphic undifferentiated sarcoma is extremely rare and aggressive, and is associated with a poor prognosis; only 14 cases of splenic pleomorphic undifferentiated sarcoma have been documented in the English literature. We discuss a case of a 56-year-old woman with iron-deficiency anaemia, early satiety and left upper-quadrant pain, who was preoperatively diagnosed with a large splenic cyst following thorough investigation. This was excised in an elective procedure. Unfortunately, histology confirmed splenic pleomorphic undifferentiated sarcoma. Following a review and summary of the literature, we discuss key differentials between splenic cysts and splenic pleomorphic undifferentiated sarcoma. This case highlights that iron-deficiency anaemia is unusual in splenic cysts and more sinister causes must be considered.

RESUMO

Adventitial cystic disease (ACD) is a rare condition in which a mucinous cyst forms within the adventitia, usually in arteries but rarely in veins. A 79-year-old patient presented with stomachache and nausea. Computerized tomography showed pelvic cysts on either side of the pelvis. The right tumor was 120×100 mm, and the left tumor was 45×35 mm. Our diagnosis was bilateral ovarian tumors and we performed laparoscopic tumor resection. In the abdominal cavity, we saw that the left ovary was swollen by about 3-4 cm and the right ovary was normal size. There was a mucous cyst located in the right retroperitoneal cavity that adhered around and bordered the right external iliac vein and the right obturator nerve. We peeled the adhesion away carefully and resected the tumor but the operation caused temporary obturator nerve paralysis. From pathological examination, we diagnosed the right retroperitoneal cyst to be venous ACD originating from the right external iliac vein. We found that venous ACD can grow as large as a pelvic tumor and is difficult to distinguish from an ovarian tumor, which is why we chose laparoscopic surgery. In this case, we performed the operation laparoscopically and no sequelae or recurrent tumor appeared during a 1-year follow-up. However, graft replacement is sometimes necessary for ACD, thus venous ACD should be considered a differential diagnosis and a surgical strategy should be developed when pelvic tumors are observed.
