Spontaneous atraumatic rupture of the urinary bladder following alcohol intoxication: A rare case report.

Key Clinical Message: Consideration of spontaneous urinary bladder rupture in the differential diagnosis of acute abdominal pain for alcohol-abusing patients is crucial for ensuring timely surgical intervention and preventing life-threatening complications due to its high associated morbidity and mortality. Abstract: Spontaneous rupture of the urinary bladder (SRUB) is a rare but critical urological emergency, typically associated with malignancy, neurogenic dysfunction, or previous radiation therapy. Here, we present a unique case of SRUB in a 65-year-old chronic alcoholic male who presented with acute lower abdominal pain following heavy alcohol consumption. Initial evaluations revealed leukocytosis, elevated serum creatinine levels, and ultrasound findings suggestive of bladder rupture. Computed tomography confirmed the diagnosis, indicating an intraperitoneal rupture with associated hematoma. Immediate surgical repair was performed, leading to a successful outcome. This case underscores the importance of considering SRUB in patients with acute abdominal pain, especially in the context of alcohol intoxication, and highlights the diagnostic and therapeutic challenges associated with this condition. Early recognition and intervention are crucial to prevent life-threatening complications associated with urinary bladder rupture.

Repair of an Isolated Sternal Head Tear of the Myotendinous Junction of the Pectoralis Major Using Knotless Suture Anchors: Case Report and Literature Review.

Although considered a relatively uncommon sports injury, publications on pectoralis major (PM) injuries have increased in the last couple of decades. Knowledge of the complex anatomy of the PM muscle is important in diagnosing, understanding the complexity of the injury, and determining the suitable modality of management of these injuries. Despite the increase in publications, there is no consensus on the superiority of any proposed surgical management. We present a case of a recreational body builder who presented to our clinics with a rare pattern of isolated musculotendinous junction of the lower fibers of the PM muscle and proposed a new technique of surgical management of such injuries using knotless suture anchors and running locked suture pattern in different directions. We then conducted a comprehensive review of literature of these injuries and presented a review on the pathophysiology, the various patterns of these injuries, and the available described modalities of surgical management. Understanding the complex anatomy of the PM, the various pattens of injury, and the aid of an MRI read by an expert musculoskeletal radiologist is crucial before managing these injuries. We believe that acute surgical repair of musculotendinous junction injuries using running Krackow/Brunnell locked configuration and the use of knotless suture and anchors will provide adequate and practicable surgical repair of these injuries.

Hollow Screw Placement Combined with Percutaneous Vertebroplasty Serves as a Valuable Three-Column Intensive Treatment for Patients with Kummell's Disease and Pedicle Rupture.

Purpose: To introduce the surgical methods and clinical results of percutaneous vertebroplasty (PVP) combined with hollow screw placement as a treatment for patients with Kummell's disease and pedicle rupture. Methods: From January 2020 to January 2023, a total of 10 patients with Kummell's disease and pedicle rupture confirmed via imaging underwent three-column intensive therapy using hollow screws combined with PVP. There were two males and eight females with an average age 75.7±6.11 years old. The time of operation, bone cement injection amount, bone cement leakage during operation were recorded. X-ray and CT were reexamined after operation. The improvement in quality of life was assessed using the Oswestry Disability Index (ODI), and the improvement in low back pain was assessed using the visual analogue scale (VAS). Results: Hollow screw placement combined with PVP was successfully performed in all patients. The average operation time was 39.2±5.1 min, and the average volume of bone cement injected was 5.85±0.83mL. No leakage of bone cement into spinal canal occurred.The mean preoperative ODI score was 75.70±4.39, but this decreased significantly postoperatively(P<0.05), being 37.70±6.95 at 1 day and 26.40±4.90, 23.70±4.87, 21.70±5.46, and 20.50±4.21 at 1, 3, 6, and 12 months after the operation, respectively. The mean VAS pain score before the operation was 8.35±0.63, but the symptoms of back pain were significantly relieved after operation(P<0.05). The mean VAS scores 1 day and 1, 3, 6, and 12 months after the operation were 3.45±0.47, 2.55±0.60, 1.89±0.48, 1.50±0.27, and 1.12±0.20, respectively. Conclusion: Hollow screw placement combined with percutaneous vertebroplasty serves as a valuable three-column intensive treatment for patients with Kummell's disease and pedicle rupture. This procedure has the advantages of minimal trauma, less pain and quick recovery. The strong anchoring of bone cement and hollow screws provides stable and firm healing conditions for vertebral and pedicle fractures.

Calyceal Rupture Secondary to Nephrolithiasis: A Case Report Emphasizing Early Diagnosis and Management.

Calyceal rupture, defined as the extravasation of urine from the renal calyces into the perinephric or paranephric spaces, typically results from increased intrapelvic pressure due to urinary tract obstruction. This condition can lead to the formation of a perinephric urinoma and severe complications, such as infection, abscess formation, and impaired renal function. Timely diagnosis and management are crucial to prevent these adverse outcomes. Calyceal rupture often results from urolithiasis, with other causes including strictures, tumors, and congenital abnormalities. The rupture occurs when intrapelvic pressure exceeds the tensile strength of the calyceal walls, leading to urine leakage and potential inflammation or sepsis. Calyceal ruptures are quite rare, with their exact incidence not well-documented due to the infrequency of the condition and potential underreporting. Although relatively uncommon, the condition is more prevalent in individuals with recurrent nephrolithiasis and other predisposing factors. Timely recognition and intervention, guided by imaging studies such as non-contrast CT scans, are essential. Conservative management with medical therapy is effective in many cases, but surgical intervention may be necessary for larger stones or complications. This report presents the case of a 36-year-old female with calyceal rupture secondary to nephrolithiasis, presenting with severe flank pain. Upon initial presentation, the patient underwent a thorough workup, including imaging studies, appropriate medical management, and continuous monitoring. She was stabilized, her pain was effectively managed, and she was discharged with a scheduled outpatient follow-up. This case highlights the importance of early diagnosis, comprehensive management, and vigilant monitoring in preventing complications and promoting favorable outcomes.

Imaging findings in suspected penile fracture: alternative diagnoses and surgical correlation.

OBJECTIVES: The primary objective is to compare the imaging and surgical findings in a cohort of patients with suspected penile fracture (PF). METHODS: Retrospective cohort study of all patients with suspected PF over an 11-year period at a tertiary referral andrology centre. All dedicated presurgical imaging with ultrasound (US) and MRI was analysed and correlated with intraoperative findings; alternative diagnoses were recorded. RESULTS: 193 patients were included. 104 (54%) had alternative diagnoses to PF including dorsal vein rupture and haematoma. 99 (51%) underwent surgical exploration of which 89 (46%) had PF.US correctly confirmed the presence and marked site of fracture in 92% of cases. MRI was primarily used as a problem-solving tool (13 cases) and demonstrated a more extensive injury than US (12 cases). The reported size of tunical defect on imaging was a median of 7 mm (IQR 4-10) significantly smaller than on exploration, (median 20 mm, IQR 10-30) p < 0.0001. CONCLUSION: US has a high positive predictive value in the confirmation of penile fracture. MRI improves the detection and characterising the extent of injury. Imaging marking informs surgical incision but defect size is under appreciated on all imaging modalities. ADVANCES IN KNOWLEDGE: Penile imaging has a high positive predictive value to not only confirm the diagnosis of PF but to stage the extent of injury and mark the skin, which impacts the surgical technique. Alternative diagnoses to fracture are common and imaging could prevent unnecessary surgical exploration.

Sensitivity of the Unruptured Intracranial Aneurysm Treatment Score (UIATS) to detect aneurysms at high-risk of rupture: Retrospective analysis in a cohort of 346 patients with a proven subarachnoid hemorrhage.

INTRODUCTION: The aim of this study was to assess the capability of the Unruptured Intracranial Aneurysm Treatment Score (UIATS) to discriminate unruptured intracranial aneurysms (UIAs) at high risk for subarachnoid hemorrhage (aSAH). MATERIAL AND METHOD: During the period from January 2012 to December 2022, we included all consecutive adult patients admitted to our institution for an aSAH caused by the rupture of a saccular IA. The patient-related, aneurysm-related and treatment-related risk factors considered by UIATS were retrieved from medical records. After UIATS calculation for all ruptured IAs in the cohort, patients were categorized as "true positives (TP)" if UIATS would have (appropriately) oriented the management toward treatment, whereas patients for whom the UIATS would have (inappropriately) recommended observation were categorized as "false negatives (FN)". Patients for whom UIATS was inconclusive were categorized as "undetermined (UND)". Sensitivity of the UIATS (Se UIATS) was calculated by using the following formula: TP/(TP + FN). RESULTS: A total of 346 patients (253 women, 73%; mean age = 56 ± 1.45 years) were incorporated into the final analysis. There were 140 T P (40%), 79 F N (23%) and 127 UND (37%), leading to a Se UIATS of 63.9% (CI 58.3-69.5). Cumulatively, the UIATS failed to provide an appropriate recommendation in 60% of the entire cohort. CONCLUSION: By retrospectively applying the UIATS in a cohort of ruptured IAs, our study emphasizes how vulnerable the UIATS can be. Even if the UIATS suggests conservative management, clinicians should inform patients that there is still a small risk of rupture.

Characteristics of a Pure Acute Subdural Hematoma Caused by Intracranial Aneurysm Rupture: A Case Report and Review of Literature.

Pure acute subdural hematomas (ASDHs) due to ruptured aneurysms without subarachnoid or intracerebral hemorrhage are rare. We report the case of a 26-year-old female who presented with a pure ASDH caused by a ruptured distal anterior cerebral artery (ACA). The patient complained of sudden headache and vomiting and was transferred to our hospital. On the ambulance journey to the hospital, her consciousness level decreased suddenly just after experiencing additional pain in the head. At admission, the consciousness level was 4 points on the Glasgow coma scale with bilateral pupil dilatation. Computed tomography (CT) and CT angiography showed a left ASDH without subarachnoid hemorrhage (SAH) and a distal ACA aneurysm. Emergent hematoma evacuation was performed, but SAH and the bleeding point were not observed. Therefore, coil embolization for the distal ACA aneurysm was performed after an emergent operation. During embolization, intraoperative rupture was observed. The contrast media was seen up to the convexity subdural space along the falx. Extravasation ceased after intraaneurysmal coil embolization. Consequently, the rupture of the distal ACA aneurysm was diagnosed as the cause of the pure ASDH. The patient received additional coil embolization due to recanalization of the aneurysm without rebleeding 44 days after admission and was transferred to a rehabilitation hospital 55 days after admission to our hospital with a score of 4 on the modified ranking scale. From the reviews of 56 patients from 32 studies, including our case, we determine that an ACA aneurysm could show the distant hematomas located far from the site of a ruptured aneurysm compared with a ruptured aneurysm located in the internal carotid and middle cerebral arteries. Distant hematoma location could also lead to delayed diagnosis of aneurysms and lead to rebleeding and poor outcomes. Aneurysm rupture diagnoses should receive special attention, especially for ACA aneurysms, as the hematoma may be located far from the rupture site.

Ultra-early neurological deterioration following a brain arteriovenous malformation rupture.

Purpose: This study aims to explore the impact of ultra-early neurological deterioration (U-END) on the outcome (mortality and poor neurological status) following a brain arteriovenous malformation (BAVM) rupture and identify determinants of U-END. Methods: Patients with BAVM ruptures admitted to a single tertiary care center were retrospectively reviewed. U-END was defined as a worsening by two or more points on the Glasgow Coma Scale (GCS). U-END was tested as a potential predictor of in-hospital mortality and poor outcomes. Univariate and multivariate analyses were performed to identify determinants of U-END. Patients with U-END were also matched and compared with BAVM rupture controls presenting with a GCS close or equal to either their initial or their lowest GCS. Results: A total of 248 patients with BAVM ruptures met the inclusion criteria, with 39 (15.7%) patients presenting with U-END. U-END was not associated with and was not an independent predictor of in-hospital mortality (12.8 vs. 10.5% in the rest of the study population; p = 0.67) or poor outcomes (39.5 vs. 36.9%; p = 0.77). The only independent determinants of U-END were hydrocephalus (OR 2.6 [95%CI, 1.1-6.4]; p = 0.03) and intraventricular hemorrhage (IVH; OR 3.5 [95%CI, 1.1-11.7]; p = 0.04). When compared to the initial GCS control group, U-END patients more often presented with IVH (89.5 vs. 64.1%; p = 0.009) and hydrocephalus (73 vs. 38.5%; p = 0.003). When compared to the lowest GCS control group, U-END patients had lower early S100B serum levels (0.35 ± 0.37 vs. 0.83 ± 1; p = 0.009) and a lower rate of poor outcome (39.5 vs. 64.9%; p = 0.03). Conclusion: Ultra-early neurological deterioration in ruptured BAVMs did not result in increased mortality or poor outcomes and was most often related to IVH and hydrocephalus.

Arachnoid Cysts in Athletes with Sports-Related Concussion: A Case Series and Literature Review.

BACKGROUND: Arachnoid cysts (AC) are associated with a risk of rupture or haemorrhage following head impact and pose a potential predisposing factor for significant complications of sport-related concussion. Despite a recognised association between ACs and intracranial haemorrhage/cyst rupture, the risk profile of participating in contact sports with AC is not well defined. We report a retrospective case series of players presenting to the Birmingham Sports Concussion Clinic between 2017 and 2023 and underwent MRI head, with a comprehensive review of the prior literature. RESULTS: 432 athletes underwent MRI of which 11 were identified to have AC (middle fossa n = 8; posterior fossa n = 2, intraventricular n = 1). Average maximal diameter was 4.1 ± 1.2 cm. 64% had a protracted recovery (≥ 3 months). 9% experienced an AC specific complication (cyst rupture, complete neurological recovery, maximal diameter 6.5 cm, Galassi II, 4 previous concussions). 91% of patients (mean maximal diameter 3.9 ± 1.0 cm) experienced no complications despite multiple previous accumulated sports-related concussions (mean 3.3, range 1-9). Case studies from the literature are summarised (n = 63), with 98% reporting complications, none of which resulted in adverse or unfavourable neurological outcomes. Across prospective and retrospective cohort studies, 1.5% had a structural injury, and (where outcome was reported) all had a favourable outcome. CONCLUSIONS: AC is an incidental finding in athletes, with the majority in our cohort having sustained serial concussions without AC complication. The single complication within this cohort occurred in the largest AC, and AC size is proposed as a tentative factor associated with increased risk of contact sports participation. Complications of AC appear to be a rare occurrence. This case series and review has not identified evidence to suggest that participation in sports with AC is of significant risk, though individualised assessment and discussion of the potential risks of contact sports participation should be offered.

A Case of Spontaneous Regression of Adult Multi-system Langerhans Cell Histiocytosis Presenting as Liver Tumor Rupture.

Adult multisystem Langerhans cell histiocytosis (MS-LCH) is rare and has a poor prognosis. A 67-year-old man with MS-LCH presented with a hepatic tumor rupture and multiple masses in the lungs, liver, and pancreas. Despite the initial aggressive disease course and involvement of organs at risk, the patient experienced spontaneous regression and lesion disappearance following smoking cessation without chemotherapy. A literature review revealed a distinct subset of MS-LCH that can be managed by smoking cessation and careful observation through follow-up imaging. This suggests that careful observation through follow-up imaging may be a reasonable alternative to chemotherapy in select adult cases of MS-LCH.

Differential culprit plaque morphology in acute coronary syndrome: a comparison between very young patients (≤35 years) and older counterparts using optical coherence tomography.

Aims: Underlying mechanisms responsible for acute coronary syndrome (ACS) in young patients compared with older counterparts are yet to be explored with optical coherence tomography (OCT). This study aims to explore underlying mechanisms of ACS in ≤35- (very young) and >35-year-old (older counterparts) ACS patients using OCT. Methods and results: This was a prospective, single-centre, investigational study. Patients were divided into groups according to age (≤35 and >35 years) and further subdivided according to the underlying mechanism i.e. plaque rupture (PR) and plaque erosion (PE). A total of 93 patients were analysed. Thin-cap fibroatheroma (TCFA) was significantly higher among older counterparts than very young patients for both PR (80.0% vs. 31.8%, P = 0.002) and PE (66.7% vs. 6.3%, P < 0.001) groups. Microchannels were also significantly more prevalent among older than very young patients for both PR (65.0% vs. 18.2%, P = 0.004) and PE groups (55.6% vs.12.5%, P = 0.013). Macrophages were significantly higher in older than very young patients for both PR (25.0% vs. 0%, P = 0.018) and PE (44.4% vs. 0%, P = 0.003) groups. In contrast, fibrous cap thickness was greater in very young than older patients for both PR (105.71 ± 48.02 vs. 58.00 ± 15.76 µm, P < 0.001) and PE (126.67 ± 48.22 vs. 54.38 ± 24.21 µm, P < 0.001) groups. Intimal thickness was greater in older than very young patients for both PR (728.00 ± 313.92 vs. 342.27 ± 142.02 µm, P < 0.001) and PE (672.78 ± 334.57 vs. 295.00 ± 99.60 µm, P < 0.001) groups. Conclusion: Frequency of TCFA, microchannels, macrophages, and intimal thickness was significantly higher in older ACS patients compared with very young patients. However, fibrous cap thickness was significantly greater in very young ACS patients compared with older patients.

A case of spontaneous bladder rupture successfully conservatively treated with transurethral debridement and hyperbaric oxygen therapy.

Introduction: Spontaneous bladder rupture is a potentially life-threatening condition. Its treatment often requires invasive strategies, mainly surgical closure, or cystectomy. We present a case where we successfully treated bladder rupture employing a less invasive technique of transurethral debridement and hyperbaric oxygen therapy. Case presentation: A woman in her 80s presenting with lower abdominal pain was suspected of vesicoenteric fistula. Subsequent investigations confirmed bladder rupture to the abdominal wall, which eventually developed into a vesicocutaneous fistula. To minimize the invasiveness of treatment, a combined strategy of transurethral debridement of the fistula, and hyperbaric oxygen therapy was taken, resulting in successful outcome. Conclusion: Our approach was unique for its tolerability in comparison to conventional surgical approaches taken towards this condition.

Ruptured triple hormone-secreting adrenal cortical carcinoma with hyperaldosteronism, hypercortisolism, and elevated normetanephrine: a case report.

We report a case of a ruptured triple hormone-secreting adrenal mass with hyperaldosteronism, hypercortisolism, and elevated normetanephrine levels, diagnosed as adrenal cortical carcinoma (ACC) by histology. A 53-year-old male patient who initially presented with abdominal pain was referred to our hospital for angiocoagulation of an adrenal mass rupture. Abdominal computed tomography revealed a heterogeneous 19×11×15 cm right adrenal mass with invasion into the right lobe of the liver, inferior vena cava, retrocaval lymph nodes, and aortocaval lymph nodes. Angiocoagulation was performed. Laboratory evaluation revealed excess cortisol via a positive 1-mg overnight dexamethasone suppression test, primary hyperaldosteronism via a positive saline infusion test, and plasma normetanephrine levels three times higher than normal. An adrenal mass biopsy was performed for pathological confirmation to commence palliative chemotherapy because surgical management was not deemed appropriate considering the extent of the tumor. Pathological examination revealed stage T4N1M1 ACC. The patient started the first cycle of adjuvant mitotane therapy along with adjuvant treatment with doxorubicin, cisplatin, and etoposide, and was discharged. Clinical cases of dual cortisol- and aldosterone-secreting ACCs or ACCs presenting as pheochromocytomas have occasionally been reported; however, both are rare. Moreover, to the best of our knowledge, a triple hormone-secreting ACC has not yet been reported. Here, we report a rare case and its management. This case report underscores the necessity of performing comprehensive clinical and biochemical hormone evaluations in patients with adrenal masses because ACC can present with multiple hormone elevations.

Comparison of Histological Chorioamnionitis in Pre-Term Delivery with and without Pre-Term Rupture of Membrane.

Background: Histological chorioamnionitis (HCA) is a histologic response to intra-uterine inflammation that is usually confirmed by pathology examination after pre-term delivery and characterized by acute granulocyte infiltration into the fetal-maternal or fetal tissues. This study aimed to compare the HCA in pre-term delivery with and without pre-term rupture of membrane for assessment of its role on early neonatal outcomes and fetal heart rate patterns. Materials and Methods: This case-control study was conducted on placenta, chorionamnion, and cord of 100 cases with and without pre-term rupture of membrane between 28 0/7 and 36 6/7 weeks delivered between March 2018 and February 2021. The kind of delivery, gestational age, neonatal intensive care unit admission, a 5 min Apgar score <7, and fetal heart rate patterns in two groups with and without HCA were assessed. Results: The odds ratio (OR) for HCA was adjusted for fetal heart rate patterns, gestational age, and delivery mode (vaginal delivery or cesarean section). Vaginal delivery, gestational age, neonatal intensive care unit admission, and a 5 min Apgar score <7 were associated with HCA [OR: 2.4, 95% confidence interval (CI): 1.2-9.5, P < 0.05; OR: 0.8, 95% CI: 0.5-1.1, P < 0.05; OR: 1.1, 95% CI: 0.6-2.1, P < 0.05; and OR: 0.9, 95% CI: 0.7-1.3, P < 0.05), respectively. However, there were no specific fetal heart rate patterns associated with HCA. Conclusion: Placental histology examination in pre-term infants with low Apgar scores may be useful to investigate the association between neonatal complications in pre-term delivery and asymptomatic chorioamnionitis.

Fatal Hemoperitoneum Secondary to a Spontaneous Splenic Vein Rupture.

Spontaneous hemoperitoneum is rare and is often labeled as idiopathic because the source of bleeding is never found. We report the case of a 35-year-old male who died of a splenic vein rupture. The decedent was a chronic alcoholic with a reported history of cirrhosis and medication noncompliance. Internal examination revealed pale visceral organs, marked hemoperitoneum, a fibrotic/nodular liver, esophageal varices, and a ruptured splenic vein. Pertinent microscopic findings include liver parenchyma with bridging fibrous septa, nodules of regenerating hepatocytes, and the presence of Mallory-Denk bodies. The immediate cause of death was determined to be splenic vein rupture with the underlying cause of death being chronic alcoholism. This case is reported to emphasize the importance of correlating past medical history with thorough vascular dissection in cases of spontaneous hemoperitoneum. In a patient with fatal hemoperitoneum and risk factors for splenic vein pathology (ie, cirrhosis, portal vein hypertension), a high suspicion should be kept for splenic vein rupture.

Fetal Urinary Ascites From Bladder Rupture: A Rare Complication of Posterior Urethral Valve.

Prenatal ultrasonography (USG) plays a crucial role in diagnosing fetal urinary tract anomalies and distinguishing between lower urinary tract obstructive (LUTO) and neurological causes (seen with spinal dysraphism, myelomeningocele, meningocele, and sacral agenesis) of urinary bladder distension. Fetal urinary ascites, a rare but severe complication, can result from bladder rupture associated with obstructive uropathy such as posterior urethral valves (PUV). This case study presents a rare instance of fetal urinary ascites due to PUV detected during prenatal ultrasonography at 20 weeks of gestation (WOG). By highlighting this uncommon but clinically significant condition, we aim to enhance the understanding and management of similar cases in clinical practice.

Spontaneous Rupture of a Non-scarring Gravid Uterus: A Late and Haphazard Diagnosis in the Postpartum Period.

This paper reports the case of a spontaneous rupture of a non-scarring gravid uterus seen four days after vaginal delivery and provides an update on this rare pathology, which can be functionally and vitally life-threatening. Uterine rupture of a healthy gravid uterus can occur as a result of structural abnormalities of the uterine tissue framework or uterine parietal fragility due to pathological phenomena such as septic states. On admission, the clinical picture is generally that of an acute abdomen with a hypogastric origin, with or without hemodynamic instability and an altered general condition, depending on the presence of an underlying advanced uterine infection. Medical imaging, mainly ultrasound and CT scan with iodine contrast, enables visualization of the uterine breach and a precise assessment of the damage. Surgery is the treatment of choice for repairing the breach and ensuring hemostasis. This case study sheds light on this pathology, familiarizing us with its clinical and radiological picture, as well as its post-treatment prognosis.
