Lipomas are the most common type of soft tissue mesenchymal tumors. They are typically located subcutaneously and consist of mature fatty tissue. When they occur under the enclosing fascia, they are called deep-seated lipomas. Infrequently, lipomas can arise inside the muscle and are called intramuscular lipomas. Intramuscular lipomas have been commonly investigated and categorized in the same group as other deep-seated and superficial lipomatous lesions. Their clinical, histological and imaging characteristics may resemble well-differentiated liposarcomas, further adding to the difficulties in the differential diagnosis. This article summarizes the available literature and describes the typical epidemiological, pathological and clinical features of intramuscular lipomas, as well as delineating their treatment and prognosis.

Abstract Objectives. To present a step by step approach for the diagnosis of adrenal incidentaloma (AI). Method. An extensive review of the literature was conducted, searching the Pub-Med and Google Scholar using the Mesh terms; Adrenal; Incidentaloma; Adrenal tumours; Radiology; Diagnosis. We also did a cross-referencing search of the literature. Comments on the new European guidelines are presented. Results. The majority of the tumours are non-functioning benign adenomas. The most important radiological characteristic of an adrenal incidentaloma is the radiation attenuation coefficient. Wash out percentage and the imaging characteristics of the tumour may help in diagnosis. Conclusion. Density less than 10 HU is in most cases characteristic of a lipid rich benign adenoma. More than 10 HU or/and history of malignancy raise the possibility for cancer. 1 mg dexamethasone test and plasma metanephrines should be done in all patients. If there is history of hypokalemia and/or resistant hypertension we test the plasma aldosterone to plasma renin ratio (ARR). Newer studies have shown that tumours even nonfunctioning and less than 4 cm may increase the metabolic risks so we may consider surgery at an earlier stage.

✓Although many arachnoid cysts are discovered incidentally and require no intervention, a small subset has been known to rupture. Note that rupture can occur either spontaneously or in association with trauma. Based on a review of the literature on ruptured arachnoid cysts, it appears that patients with middle fossa cysts are more likely to experience symptomatic traumatic rupture than those with cysts in other locations. Middle fossa cysts are more commonly associated with hemispheric subdural collections and hematomas than are any other cysts. The authors report on two representative cases illustrating the distinct presentation, imaging characteristics, and management of these cysts.

✓ A case of primary embryonal-cell carcinoma of the parietal lobe is reported. The unusually chronic presentation of such a malignant tumor is described. The atypical computerized tomography and magnetic resonance imaging characteristics of this lesion are presented. Review of the literature yielded no previous reports of a lobar embryonal-cell carcinoma. The rarity of intracranial germ-cell tumors presenting off the midline is discussed.

Background: Subgaleal hematoma (SGH) is generally documented within the neonatal period and is rarely reported as a result of trauma or hair braiding in children. While rare, complications of SGH can result in ophthalmoplegia, proptosis, visual deficit, and corneal ulceration secondary to hematoma extension into the orbit. Although conservative treatment is preferential, expanding SGH should be aspirated to reduce complications associated with further expansion. Case Description: A 12-year-old African-American female with no recent history of trauma presented with a chief complaint of headache along with a 2-day history of enlarging 2–3 cm ballotable bilateral frontal mass. Hematological workup was negative. The patient’s family confirmed a long history of hair braiding. The patient was initially prescribed a period of observation but returned 1-week later with enlarging SGH, necessitating surgical aspiration. Conclusion: SGH is rare past the neonatal period, but can be found in pediatric and adolescent patients secondary to trauma or hair pulling. Standard workup includes evaluation of the patient’s hematological profile for bleeding or coagulation deficits, as well as evaluation for child abuse. Although most cases of SGH resolve spontaneously over the course of several weeks, close follow-up is recommended. The authors present a case of a 12-year-old female presenting with enlarging subgaleal hemorrhages who underwent surgical aspiration and drainage without recurrence. A literature review was also conducted with 32 pediatric cases identified, 20 of which were related to hair pulling, combing, or braiding. We review the clinical course, imaging characteristics, surgical management, as well as a review of the literature involving subgaleal hemorrhage in pediatric patients and hair pulling.

Primary angiosarcoma of the breast is a rare tumor, with approximately 170 cases reported in the literature (1-3, 10, 11, 15). Reports on the imaging characteristics of these tumors have been occasional until a recent review by Liberman et al. (11). Diagnostic imaging of the masses include mammographic and ultrasound examinations (5): the imaging characteristics of the tumor can be nonspecific and sometimes heterogeneous (11). Only recently was one case evaluated with magnetic resonance imaging (11). We present the mammographic and sonographic features of a case of primary angiosarcoma of the breast with an inflammatory appearance.

The authors report the treatment of a rare type of dural arteriovenous fistula of the paracavernous venous plexus. These fistulas can mimic carotid-cavernous fistulas in both imaging characteristics and clinical presentation, but the anatomical differences require differences in management. The authors describe an integrated open surgical and direct endovascular embolization approach and review of the literature pertaining to the anatomy of and treatment options for paracavernous fistulas.
