Imperforate hymen causing hematocolpos, hematometra and acute urinary retention in an adolescent girl.

Abdominal pain is a common occurrence in the adolescent demographic, encompassing a wide range of differential diagnoses. The etiology of abdominal pain can be categorized into gastrointestinal, urologic, and gynecologic causes. In the female pediatric population, acute urinary retention is an uncommon but noteworthy source of abdominal pain, typically resulting from an obstructive process. Hence, it is imperative to perform a comprehensive physical examination prior to deciding on the management approach. We present the case of a 11-year-old girl who visited the emergency department due to suprapubic discomfort and acute urinary retention. The patient had no significant medical or surgical history, and her neurological examinations were normal. Urinary catheterization drained 500 mL of urine. Abdominal ultrasonography revealed a hematocolpos compressing the urinary bladder. Further gynecologic history indicated that the patient had not yet experienced menarche. Consequently, a cruciate incision was performed, which resolved her urinary retention. This article aims to emphasize that although rare, imperforate hymen should be considered as a potential cause of acute urinary retention during adolescence. If an adolescent presents with abdominal pain and voiding difficulties, it is crucial to obtain a detailed gynecological history and conduct a thorough physical examination of the genital introitus.

Yolk sac tumor of the liver in an infant: A case report.

Yolk sac tumors can occur in various extragonadal sites, including the hepatobiliary tract, and are often associated with elevated serum alpha-fetoprotein. We report the case of a 14-month-old male infant presenting with abdominal pain and distension. Ultrasound and computed tomography scans of the abdomen revealed contiguous hepatic masses with lobulated contours, containing areas of necrosis. The patient underwent surgical resection, and histological studies confirmed the diagnosis of a yolk sac tumor. The occurrence of a yolk sac tumor in the liver is extremely rare. Ultrasound and cross-sectional imaging can be highly effective in diagnosing these tumors when combined with biopsy procedures to confirm the diagnosis. Although rare, yolk sac tumors of the liver should be considered a differential diagnosis for hepatic masses.

Hypertrophic olivary degeneration secondary to a Guillain Mollaret triangle cavernoma: Two case report.

Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration. It is caused by a damage at the Guillain-Mollaret triangle (GMT), which is defined by three anatomical structures: the dentate nucleus, the red nucleus, and the inferior olivary nucleus (ION). Clinically, it may be revealed by palatal myoclonus. On MRI, it appears as a unilateral or bilateral enlargement of the inferior olivary nucleus which shows a high signal intensity on T2-weighted images, with sometimes a cerebellar atrophy. Here we report 2 cases of healthy patients which present hemorrhagic brainstem cavernomas, complicated later by the development of palatal myoclonus and cerebellar ataxia, with MRI features corresponding to an (HOD) secondary to a (GMT) cavernoma. The purpose is to explain the mechanism of (HOD) subsequent to lesion in (GMT), and to describe magnetic resonance imaging features.

Endothelial cyst of the adrenal gland: A rare case report.

Adrenal gland cysts are rare and uncommon manifestations. Mostly asymptomatic, discovered incidentally during radiological studies or at autopsy, or without characteristic symptoms. The spectrum of these entities may include benign cysts or malignant cystic neoplasms. They are classified into four types: pseudocysts, endothelial cysts, epithelial cysts, and parasitic cysts. Though pseudocysts are reported to be the most frequently clinically recognized adrenal cysts in surgical series, endothelial cysts are more frequent in autopsy series. Even with advanced imaging modalities, it is still difficult to differentiate a benign adrenal neoplasm from a malignant one. As a result, getting a definitive diagnosis and starting treatment is challenging. In both symptomatic and asymptomatic cases with a large diameter or increasing sizes during follow-up, or with any abnormality of adrenal hormones, surgery is the treatment of choice in symptomatic. Herein, we present a 47-year-old female with a nonfunctional left adrenal endothelial cyst, who was incidentally found during a computerized tomography scan. The patient presented with left-sided nephritic colic due to renal lithiasis. The objective of this paper is to recall the clinical characteristics and to specify the diagnostic contribution of imaging as well as the therapeutic modalities of this entity.

Antenatal imaging diagnosis of thoraco-omphalopagus conjoined twins.

Conjoined twins occur in an estimated one in every 200,000 live births. The etiology remains largely speculative, with genetic and environmental factors being considered. The thoraco-omphalopagus type accounts for approximately 40% of cases, making it a focal point for clinical and radiological research. Radiological imaging plays a pivotal role in delineating anatomical details, offering insights into the feasibility of surgical interventions and informing parental counselling regarding prognosis and management options. We present a case of thoracoomphalogus conjoined twins diagnosed during the third trimester of pregnancy in a 19-year-old woman. The detailed radiological assessment using ultra-sound and MRI provided crucial information on organ sharing and vascular anatomy, which is critical for management strategies. This case underscores the critical role of prenatal imaging in detecting complex congenital anomalies, facilitating informed decision-making by healthcare providers and families.

Voluminous cervical polyp delivered: a case report.

Cervical polyps are common gynecological findings, typically small and benign. However, larger polyps can mimic malignant neoplasms and pose diagnostic challenges. We present a case of a 40-year-old woman with a large cervical polyp, highlighting the critical role of radiological imaging in diagnosis and management. The lesion was successfully resected, with histological examination confirming a benign nature. This case underscores the necessity for careful evaluation of large cervical polyps to ensure accurate diagnosis and treatment.

Giant breast lipoma: A case report.

INTRODUCTION: Lipoma is the most common benign tumor of adipose tissue. Giant lipoma of the breast is defined as lesions larger than 10 cm and weighing more than 1000 g. A breast lipoma rapidly enlarging and fast growing; can be managed as a malignant tumor. It is crucial to make a correct diagnosis to prevent an overtreatment. CASE PRESENTATION: A 48-year-old patient presented with a painless, huge rapidly growing tumor in her right breast. Physical examination and imaging studies was suggestive of benign lipomatous breast tumor: A breast lipoma, a fibroadenolipoma or adenolipoma, an angiolipoma, or a breast fatty hamartoma. The patient underwent surgical excision of the mass, and histological examination confirmed the diagnosis of a giant breast lipoma. DISCUSSION: Giant breast lipoma is a rare benign tumor that develops in the breast tissue. They can mimic various breast conditions, even neoplastic conditions. Giant breast lipomas are often treated with surgical excision to avoid recurrence. CONCLUSION: Giant breast lipoma rapidly growing can pose a diagnostic challenge due to its resemblance to various benign or malignant pathologies. Unnecessary invasive investigations can be avoided with better understanding and improved imaging-based diagnosis of giant breast lipoma.

Demons-Meigs syndrome caused by a giant ovarian fibroma: A case report.

Demons-Meigs syndrome is a very rare entity. It combines a benign ovarian "fibroma-like" tumor with ascites and hydrothorax. The notion of benignancy is the key point. CA-125 levels are most of the time normal, but high levels can be observed in rare cases which makes it difficult to have a diagnostic. We present here the case of a 43-year-old female patient who presented with abdominopelvic pain. Imaging discovered a 30 cm large intraabdominal mass with ascites and bilateral pleural effusion. Surgical resection of the tumor was performed, and pathology identified an ovarian fibroma. No postintervention complications were observed, with resorption of the ascites and hydrothorax.

Progressive ataxia and palatal tremor (PAPT) with hypertrophic olivary degeneration (HOD): A case report.

Palatal tremor has been subdivided into essential (EPT) and symptomatic palatal tremor (SPT). Progressive ataxia and palatal tremor syndrome (PAPT) is a subgroup of symptomatic palatal tremor (SPT). It can be divided into familial and sporadic forms. Sporadic PAPT is characterized by progressive cerebellar degeneration. The cause of sporadic PAPT remains uncertain. MRI examination found an enlarged appearance of the olivary nuclei with increased signal intensity on T2 and FLAIR images. Here we report a case of a mid-adult-onset man which presents a worsening cerebellar progressive ataxia with palatal tremor, in whom imaging reveals abnormalities of the olivary nuclei with tardive cerebellar atrophy which has been diagnosed as a sporadic PAPT.

An unexpected complication: Air embolism during contrast-enhanced computed tomography.

Air embolism is often an iatrogenic complication that may occur in venous or arterial circulation depending on the port of entry. We present a case of a 40-year-old female who had a venous air embolism in the pulmonary artery as a consequence of the injection of a contrast agent. She experienced dyspnea and chest pain following a contrast-enhanced chest computed tomography imaging. She was successfully treated and discharged from our hospital. Early detection of this clinical condition is essential to prevent morbidity and mortality.
