Mailleux et al. [52] presented two patients with degenerative spondylolisthesis of the lumbar spine causing canal stenosis not apparent on supine MRI examination due to reduction of the listhesis in that position. The patients showed an unusually large area of hypersignal at the facets on T2-weighted images. The authors concluded that their observation should raise the suspicion of spondylolisthesis in the standing position and an underestimation of the stenosis in the supine position. These results seem to encourage the use of axial loaded MRI in patients with suspected instability as well. Epidural Lipomatosis
The skin and subcutaneous tissues

Multiplicity Patients often have many lipomas, or have had others excised in the past. Multiple contiguous lipomas cause enlargement and distortion of the subcutaneous tissues. This condition is called lipomatosis. It usually occurs in the buttocks and sometimes in the neck.

Symptomatic spinal EL is a rare entity that can manifest with variable clinical presentation, thus necessitating an individualized treatment approach. Treatment can be divided into conservative management and surgical intervention for refractory cases. Conservative treatment entails close clinical follow up with radiographic surveillance, symptomatic relief, and reversal of underlying conditions that may be associated with lipomatosis, such as endogenous or exogenous corticosteroid excess or weight loss in obesity [1, 2, 5, 8–13]. Surgical intervention is preferred when initial conservative measures fail to provide symptomatic relief, documented syrinx progression, or if the patient demonstrates progressive neurologic decline. Ishikawa et al. retrospectively evaluated symptomatic spinal epidural lipomatosis in seven patients and concluded that the number of involved vertebral levels and obesity were strongly correlated with neurologic symptoms [8]. Kellett et al. analyzed nine patients who presented with symptomatic spinal EL and neurologic deficits. All patients underwent laminectomy and resection of extradural fat at the compressed levels and experienced symptom improvement or resolution [4].

Interatrial septum thickness in the general population is about 6 mm and usually it increases to about 7 mm in aged population [35]. Interatrial septum hypertrophy (IASH) and lipomatosis have been defined when thickness is >8 mm and >15 mm, respectively. IASH is common in elderly people and is related with arterial hypertension and smoke but not with vascular disease. Lipomatosis of interatrial septum is a benign tumoral processcharacterized by fat accumulation in the interatrial septum [36]. Both conditions may have a deep impact on transcatheter closure because in case of both PFO and ASD, a stiff device such as those of the Amplatzer family should be contraindicated, due to the inability of such a device to stretch the waist zone of more than 7–8 mm.

A 42-year-old Thai man developed painless slow progressive masses of both lower eyelids for 3 years following neck swelling. He had a history of hypertension and previously treated for pulmonary tuberculosis. He also had a history of excessive alcohol consumption, 750 cc per day for 10 years. Physical examination showed marked swelling with soft consistency of both lower eyelids (Figure 1a,b). He had neck swelling secondary to fat infiltration, typical of “Madelung’s collar”. Best visual acuities were 20/30 of the right eye and 20/40 of the left eye. Color vision testing using Ishihara plates was normal in both eyes. Hertel exophthalmometry revealed axial proptosis of 21 mm bilaterally. Extraocular movements were full. Laboratory testing showed an elevated fasting blood sugar of 259 mg/dl (normal 70–110 mg/dl), abnormal liver enzyme (SGOT 112 U/L (normal < 50 U/L)), hypercholesterolemia (cholesterol 264 mg/dl (normal 150–200 mg/dl)), and thyroid function tests were unremarkable. CT scan showed excessive symmetrical non-encapsulated fat deposition in the orbital fat extending into the lower eyelids (Figure 2 a,b). In addition, there was fat deposition in the salivary glands, subcutaneous tissue along the neck and under the sternocleidomastoid muscles and supraclavicular areas. Debulking of the inferior pre and postseptal orbital fat was performed via subciliary incisions on both lower lids. Histopathology demonstrated mature adipose tissue interspersed with thin fibrous septae. The proptosis values remained unchanged postoperatively. He developed recurrent lipomatosis of both lower eyelids 1 year after surgery.
