3. Delayed Incisional Hernia Following Minimally Invasive Trans-Psoas Lumbar Spine Surgery: Report of a Rare Complication and Management (PubMed)

Delayed Incisional Hernia Following Minimally Invasive Trans-Psoas Lumbar Spine Surgery: Report of a Rare Complication and Management Lateral lumbar interbody fusion (LLIF) has proved to be a safe tool in the armamentarium of spine surgeons for a variety of lumbar disorders. However, it has some complications related to specific approaches. Incisional hernia following abdominal surgery and anterior spinal surgery is commonly described; however, it is extremely rare following LLIF, with only 1 (...) closure of the deep obliques is often disappointing. The treating surgeon should be aware of this complication and aggressively surveil for the warning signs, and patients should be counseled about this potential complication.

4. Unusual Locations of Pancreatic Pseudocysts in Lumbar Triangle, Psoas Muscle and Intercostal Space, and Obturator Externus (PubMed)

Unusual Locations of Pancreatic Pseudocysts in Lumbar Triangle, Psoas Muscle and Intercostal Space, and Obturator Externus Pancreatic pseudocyst develops as a complication of both acute and chronic pancreatitis. Although the common location of pseudocyst is lesser sac, extension of pseudocyst can occur into mesentery, retroperitoneum, inguinal region, scrotum, liver, spleen, mediastinum, pleura, and lung. Extension of pseudocyst into psoas muscle and lumbar triangle is extremely rare (...) . The development of pseudocyst in lumbar triangle is radiologically equivalent and further extension of Grey Turner's sign seen clinically in acute pancreatitis. This extension occurs due to the destructive nature of pancreatic enzymes. The lumbar triangle is the site of anatomic weakness in the lateral abdominal wall in the lumbar region. We report the case of a 35-year-old alcoholic male patient who presented with abdominal pain followed by distension and swelling in the right lumbar region for 1 week

5. The adrenal psoas sign: surgical outcomes following a simple technique to maximize removal of extracortical adrenal tissue during bilateral laparoscopic adrenalectomy. (PubMed)

The adrenal psoas sign: surgical outcomes following a simple technique to maximize removal of extracortical adrenal tissue during bilateral laparoscopic adrenalectomy. Bilateral laparoscopic adrenalectomy (BLA) is an effective therapy for the management of persistent hypercortisolism in patients after failed transphenoidal pituitary tumor resection for Cushing's disease. Extracortical adrenal tissue has been identified as a source of persistent hypercortisolism and, if not resected along (...) with both adrenal glands, may lead to treatment failure. We report a reliable and reproducible technique called the "psoas sign" for BLA in patients with Cushing's disease which reduces the likelihood of retained extra-adrenal cortical rests and may reduce intraoperative complications.A 16-year retrospective review of all consecutive patients who underwent transabdominal BLA at a single tertiary care center was performed. All patients underwent BLA utilizing the psoas sign technique and all procedures

6. Bilateral Femoral Neuropathy Following Psoas Muscle Hematomas Caused by Enoxaparin Therapy (PubMed)

Bilateral Femoral Neuropathy Following Psoas Muscle Hematomas Caused by Enoxaparin Therapy BACKGROUND Femoral neuropathy as a result of retroperitoneal hemorrhage most commonly occurs following pelvic and lower extremity trauma, but has been described to develop as a less frequent complication of anticoagulation. CASE REPORT We present the case of a 64-year-old white woman who was being treated for pulmonary embolism and deep venous thrombosis with enoxaparin. In the course of her treatment (...) , she was noted to be hypotensive, with a sudden drop in hematocrit. She had been previously ambulatory, but noted an inability to move her bilateral lower extremities. A diagnosis of bilateral femoral neuropathy as a result of psoas hematomas caused by enoxaparin was made. Anticoagulation was discontinued and she was treated conservatively, with an excellent outcome. At the time of discharge to a rehabilitation center, she had regained most of the motor strength in her lower extremities

9. Correlation of CT signs with lymphatic metastasis and pathology of neuroblastoma in children (PubMed)

Correlation of CT signs with lymphatic metastasis and pathology of neuroblastoma in children Correlation between computed tomography (CT) signs, lymphatic metastasis and pathological features of neuroblastoma (NB) in children was investigated. A total of 374 child patients diagnosed with NB via CT scan and pathological section in Department of Pediatric of Xuzhou Children's Hospital from March 2011 to January 2017 were collected, and their clinical data were retrospectively analyzed. According (...) to CT signs, NB calcification and invasion to surrounding tissues were evaluated, and the tumor site, tumor size, lymphatic metastasis, pathological types and clinical prognosis were analyzed. In plain CT scan, 160 cases showed clear tumor mass, and 214 cases showed blurred mass; 78 cases of tumors were uniform in density, and 296 cases were not uniform in density. Besides, there were 351 cases of calcification in mass. There were 106 cases of axial rotation of kidney, 53 cases of enlargement

10. Clinical signs of retroperitoneal abscess from colonic perforation: Two case reports and literature review. (PubMed)

Clinical signs of retroperitoneal abscess from colonic perforation: Two case reports and literature review. Retroperitoneal colonic perforation is a rare cause of retroperitoneal abscess. It presents, more frequently in frail elderly patients, with heterogeneous signs and symptoms which hamper the clinical diagnosis. Subcutaneous emphysema with pneumomediastinum and iliopsoas muscle abscess are unusual signs. Colonic retroperitoneal perforation may be consequent to diverticulitis or locally (...) advanced colon cancer. Due to the anatomy of the retroperitoneal space and different physiopathology, diverticular perforation may present with air and pus collection; on the other hand perforated colon cancer may cause groin mass and psoas abscess. We reported 2 cases of colonic retroperitoneal perforation from diverticulitis and locally advanced colon cancer, respectively. Aim of this report is to improve differential diagnosis based on clinical signs.A 71-year-old man presented with pain in his left

11. The psoas sign, hepatic angle, normal patients, and everyday practice (PubMed)

The psoas sign, hepatic angle, normal patients, and everyday practice While extensive previous references in the literature leave little doubt that disease in the posterior pararenal space can obliterate the psoas margin either in its entirety or in part, little work has been done to evaluate the frequency of when the psoas cannot be visualized in normal individuals. The data presented here indicate that as the right psoas can be expected to be absent in normal patients from 16 to 43 (...) % of the time, therefore one cannot ;lean' heavily on it as a clinical tool. On the other hand, absence of the left psoas margin on a single film in the proper clinical setting may be sufficient to draw one's attention to the retroperitoneal space, more particularly the posterior pararenal space, as a possible site of abnormality. However, ancillary radiographic signs such as mass displacement, gas, calcium, or abnormal depositions of fat, should be carefully sought. Preservation of either or both psoas

12. A sign on CT that predicts a hazardous ureteral anomaly (PubMed)

A sign on CT that predicts a hazardous ureteral anomaly An aberrant course of the distal ureter can pose a risk of ureteral injury during surgery for inguinal hernia repair and other groin operations. In a recent case series of inguinoscrotal hernation of the ureter, we found that each affected ureter was markedly anterior to the psoas muscle at its mid-point on abdominal CT. We hypothesized that this abnormality in the abdominal course of the ureter would predict the potentially hazardous (...) aberrant course of the distal ureter.We reviewed all evaluable CT urograms performed at St. Louis University Hospital from June 2012 to July 2013 and measured the ureteral course at several anatomically fixed points.93% (50/54) of ureters deviated by less than 1cm from the psoas muscle in their mid-course (at the level of the L4 vertebra). Reasons for anterior deviation of the ureter in this study included morbid obesity with prominent retroperitoneal fat, congenital renal abnormality, and post
