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.

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.

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.

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.

Pediatric myositis ossificans circumscripta following traumatic hip dislocation: A case report.

Myositis ossificans is non-neoplastic heterotopic bone forms in skeletal muscle. We recognize 3 subtypes: fibrodysplasia ossificans progressiva, myositis ossificans with no history of trauma (nontraumatic or pseudomalignant), and circumscribed or traumatic myositis ossificans. Traumatic myositis ossificans circumscripta has not, as far as we are aware, been previously documented as a complication of traumatic hip dislocation. We present the radiological findings of a 10-year-old girl with Thevenards syndrome, whose traumatic hip dislocation was complicated by circumstantial myositis ossificans. X-rays and computed tomography scan enabled us to diagnose by the presence of mature bone in the periphery of the lesion with a smooth contour and well separated from the bone. The treatment of dislocation and complication was nonoperatively.

Omental infarction found incidentally during metastatic workup: A report of 2 cases.

Omental infarction is an uncommon cause of acute abdominal pain that can occur in different several locations. We report 2 cases of omental infarction diagnosed at computed tomography (CT) scan performed as part of routine oncological surveillance, one right-sided and the other left sided. This paper illustrates the range of CT scan findings and highlights the important clinical implications of this radiological diagnosis.

Male breast myofibroblastoma: Imaging features and ultrasound-guided core biopsy diagnosis.

Mammary myofibroblastoma is a rare mesenchymal neoplasm that typically presents in older men and women. Less commonly, these benign tumors may also occur in soft tissues located outside of the breast, in which case they are referred to as mammary-type myofibroblastomas. The histologic composition of this benign spindle cell tumor can be markedly varied. We present one such case of myofibroblastoma of the male breast, describing its sonographic appearance and its diagnosis using ultrasound-guided core biopsy.

Laparoscopic Management of an Inflammatory Pseudotumor Mimicking a Locally Advanced Renal Carcinoma: A Diagnostic Pitfall.

Inflammatory pseudotumors of the kidney are an infrequent entity. More frequently described in the lung, the genitourinary tract location is rare. Commonly described in the bladder, the kidney damage remains exceptional. Herein, we report the case of 60 years old man with a history of flank pain, initially diagnosed with a locally advanced left renal carcinoma invading the left colon. Then, after performing a laparoscopic radical nephrectomy, the histopathological diagnosis of inflammatory pseudotumor of the left kidney has been made.
